It was a day without hope: March 11, 2011. The 8.9 magnitude earthquake set off a devastating tsunami that washed away coastal cities in Northeastern Japan. Thousands of homes were destroyed. Roads were impassable, transportation destroyed or shut down, and power remained down for weeks in the cold temperatures of early spring. All around were scenes of desperation, as stranded survivors cried for help, buried alive under the rubble of what remained of their cities, communities, and homes. Things couldn’t get much worse when the damage to the Fukushima Daiichi nuclear reactor was discovered, making it impossible to return home. Over three hundred thousand were left homeless and over eighteen thousand people died.
March 11, 2011 was a day without hope for me, as well. Like many around the world, I couldn’t believe that yet another massive earthquake and tsunami of such magnitude—like the Southeast Asian tsunami of 2004—had wrought so much destruction and devastation. Yet on this same day, I attended the funeral for my husband who had died suddenly on March 2, 2011. I felt as if I was buried by the rubble of grief over his lost life and the life we shared together for nearly twenty years.
Even those unacquainted with the biblical narrative have likely heard the familiar story of the raising of Lazarus from the dead. It is one of the critical events in John’s Gospel for it is the last miracle Jesus performs prior to his entry into Jerusalem and his crucifixion.(1) As readers of this story, we have the privilege of knowing the triumphant ending, but for Mary, Martha, and all who loved Lazarus, his death and burial must have also felt like a day without hope. Mary and Martha had sent word to Jesus informing him of their brother’s illness. Surely he would rush to their aid and save their ailing brother. Lord, he whom you love is ill.
But rather than rushing to their side, or simply speaking the words of healing as he had done for others, Jesus delays going to them. The Gospel reads: Now Jesus loved Martha and her sister and Lazarus, so when he heard that he was ill, he stayed two days longer in the place where he was. Jesus delays going to them and this sets up one of the difficult tensions in this passage. Jesus loves this family, and yet his delay means Lazarus will die, and worse, his delay will prompt the grief, heartache, and misunderstanding that must have arisen by his absence.
When Jesus does arrive, Lazarus has been dead for four days. Jewish belief taught that after three days the soul would leave the body and corruption would set in. So for those who mourned Lazarus, there was no hope of resuscitation or of saving him now. The fourth day was truly a day without hope. And yet this is the day Jesus shows up.
The story of the raising of Lazarus is prefaced by a statement of its purpose: This illness does not lead to death; rather it is for God’s glory, so that the Son of God may be glorified through it. In stating that he will be glorified, Jesus is not declaring that now that he has arrived to save the day, he will be admired and praised as the hero of the story. Rather, the raising of Lazarus will speed his own death. From that day on the religious leaders counseled together how they might put him to death. The glory of the resurrection would first be the horror and despair of Good Friday and Holy Saturday.
The passion of Jesus bleeds through the surface of the story. Jesus was “deeply moved in spirit and troubled,” and he wept. The crowd who saw him weeping said, “See how he loved him!” Yet they couldn’t possibly understand all that was going on. Jesus knows that calling Lazarus out of the tomb means that he must enter it himself. The narrative makes that fact abundantly clear. The belief in Jesus as a result of this miracle prompts the religious leaders to plot his death. But for Jesus there is no other way because only in this act can he be the resurrection and the life for the world.
Yet, Martha, Mary, and Lazarus are not simply props for a spiritual story. They are real people trapped in death and grief, who do not yet know the end of the story. Jesus will bring life, but he does so as one who ministers among the suffering. Although the readers of this story were not there, Jesus holds them in mind too. Have you believed because you have seen me? Blessed are those who have not seen and yet believe.
For some women affected by the tsunami of March 11, 2011, a social enterprise is helping them to remove the grave clothes. Nozomi, which means ‘hope’ in Japanese, is the name of an initiative bringing sustainable income, community, and hope to the women in Northeastern Japan. One third of the women involved are single mothers and grandmothers; most of these women lost their livelihood, a family member, and/or their home when the tsunami crashed into their world in 2011. With broken pieces of pottery left in the wake of the tsunami, they are now creating jewelry. Broken shards are transformed into beautiful treasures. Their lives, too, are filled with renewed dignity and hope following the devastation of the tsunami.
The raising of Lazarus is our human story. We who dwell in days without hope can be brought to life. Jesus stands at the edge of every tomb, shouting “Come forth!” He calls forth life and liberation from all of our hopeless fourth days. He calls forth life in the midst of certain and confirmed death. We can substitute our own name for that of Lazarus, hear the call of Jesus, and walk into the light of day. In the entombed, hopeless reality of life’s darkness and suffering, we can hear an untimely voice. And it is a voice that calls us by name.

Different forms of fluctuations of the terrestrial gravity field are observed by gravity experiments. For example, atmospheric pressure fluctuations generate a gravity-noise foreground in measurements with super-conducting gravimeters. Gravity changes caused by high-magnitude earthquakes have been detected with the satellite gravity experiment GRACE, and we expect high-frequency terrestrial gravity fluctuations produced by ambient seismic fields to limit the sensitivity of ground-based gravitational-wave (GW) detectors. Accordingly, terrestrial gravity fluctuations are considered noise and signal depending on the experiment. Here, we will focus on ground-based gravimetry. This field is rapidly progressing through the development of GW detectors. The technology is pushed to its current limits in the advanced generation of the LIGO and Virgo detectors, targeting gravity strain sensitivities better than 10−23 Hz−1/2 above a few tens of a Hz. Alternative designs for GW detectors evolving from traditional gravity gradiometers such as torsion bars, atom interferometers, and superconducting gradiometers are currently being developed to extend the detection band to frequencies below 1 Hz. The goal of this article is to provide the analytical framework to describe terrestrial gravity perturbations in these experiments. Models of terrestrial gravity perturbations related to seismic fields, atmospheric disturbances, and vibrating, rotating or moving objects, are derived and analyzed. The models are then used to evaluate passive and active gravity noise mitigation strategies in GW detectors, or alternatively, to describe their potential use in geophysics. The article reviews the current state of the field, and also presents new analyses especially with respect to the impact of seismic scattering on gravity perturbations, active gravity noise cancellation, and time-domain models of gravity perturbations from atmospheric and seismic point sources. Our understanding of terrestrial gravity fluctuations will have great impact on the future development of GW detectors and high-precision gravimetry in general, and many open questions need to be answered still as emphasized in this article.

Introduction
In the coming years, we will see a transition in the field of high-precision gravimetry from observations of slow lasting changes of the gravity field to the experimental study of fast gravity fluctuations. The latter will be realized by the advanced generation of the US-based LIGO [1] and Europe-based Virgo [7] gravitational-wave (GW) detectors. Their goal is to directly observe for the first time GWs that are produced by astrophysical sources such as inspiraling and merging neutron-star or black-hole binaries. Feasibility of the laser-interferometric detector concept has been demonstrated successfully with the first generation of detectors, which, in addition to the initial LIGO and Virgo detectors, also includes the GEO600 [119] and TAMA300 [161] detectors, and several prototypes around the world. The impact of these projects onto the field is two-fold. First of all, the direct detection of GWs will be a milestone in science opening a new window to our universe, and marking the beginning of a new era in observational astronomy. Second, several groups around the world have already started to adapt the technology to novel interferometer concepts [60, 155], with potential applications not only in GW science, but also geophysics. The basic measurement scheme is always the same: the relative displacement of test masses is monitored by using ultra-stable lasers. Progress in this field is strongly dependent on how well the motion of the test masses can be shielded from the environment. Test masses are placed in vacuum and are either freely falling (e.g., atom clouds [137]), or suspended and seismically isolated (e.g., high-quality glass or crystal mirrors as used in all of the detectors listed above). The best seismic isolations realized so far are effective above a few Hz, which limits the frequency range of detectable gravity fluctuations. Nonetheless, low-frequency concepts are continuously improving, and it is conceivable that future detectors will be sufficiently sensitive to detect GWs well below a Hz [88].
Terrestrial gravity perturbations were identified as a potential noise source already in the first concept laid out for a laser-interferometric GW detector [171]. Today, this form of noise is known as “terrestrial gravitational noise”, “Newtonian noise”, or “gravity-gradient noise”. It has never been observed in GW detectors, but it is predicted to limit the sensitivity of the advanced GW detectors at low frequencies. The most important source of gravity noise comes from fluctuating seismic fields [151]. Gravity perturbations from atmospheric disturbances such as pressure and temperature fluctuations can become significant at lower frequencies [51]. Anthropogenic sources of gravity perturbations are easier to avoid, but could also be relevant at lower frequencies [163]. Today, we only have one example of a direct observation of gravity fluctuations, i.e., from pressure fluctuations of the atmosphere in high-precision gravimeters [128]. Therefore, almost our entire understanding of gravity fluctuations is based on models. Nonetheless, potential sensitivity limits of future large-scale GW detectors need to be identified and characterized well in advance, and so there is a need to continuously improve our understanding of terrestrial gravity noise. Based on our current understanding, the preferred option is to construct future GW detectors underground to avoid the most dominant Newtonian-noise contributions. This choice was made for the next-generation Japanese GW detector KAGRA, which is currently being constructed underground at the Kamioka site [17], and also as part of a design study for the Einstein Telescope in Europe [140, 139]. While the benefit from underground construction with respect to gravity noise is expected to be substantial in GW detectors sensitive above a few Hz [27], it can be argued that it is less effective at lower frequencies [88].
Alternative mitigation strategies includes coherent noise cancellation [42]. The idea is to monitor the sources of gravity perturbations using auxiliary sensors such as microphones and seismometers, and to use their data to generate a coherent prediction of gravity noise. This technique is successfully applied in gravimeters to reduce the foreground of atmospheric gravity noise using collocated pressure sensors [128]. It is also noteworthy that the models of the atmospheric gravity noise are consistent with observations. This should give us some confidence at least that coherent Newtonian-noise cancellation can also be achieved in GW detectors. It is evident though that a model-based prediction of the performance of coherent noise cancellation schemes is prone to systematic errors as long as the properties of the sources are not fully understood. Ongoing experiments at the Sanford Underground Research Facility with the goal to characterize seismic fields in three dimensions are expected to deliver first data from an underground seismometer array in 2015 (see [89] for results from an initial stage of the experiment). While most people would argue that constructing GW detectors underground is always advantageous, it is still necessary to estimate how much is gained and whether the science case strongly profits from it. This is a complicated problem that needs to be answered as part of a site selection process.
More recently, high-precision gravity strainmeters have been considered as monitors of geophysical signals [83]. Analytical models have been calculated, which allow us to predict gravity transients from seismic sources such as earthquakes. It was suggested to implement gravity strainmeters in existing earthquake-early warning systems to increase warning times. It is also conceivable that an alternative method to estimate source parameters using gravity signals will improve our understanding of seismic sources. Potential applications must still be investigated in greater detail, but the study already demonstrates that the idea to use GW technology to realize new geophysical sensors seems feasible. As explained in [49], gravitational forces start to dominate the dynamics of seismic phenomena below about 1 mHz (which coincides approximately with a similar transition in atmospheric dynamics where gravity waves start to dominate over other forms of oscillations [164]). Seismic isolation would be ineffective below 1 mHz since the gravitational acceleration of a test mass produced by seismic displacement becomes comparable to the seismic acceleration itself. Therefore, we claim that 10 mHz is about the lowest frequency at which ground-based gravity strainmeters will ever be able to detect GWs, and consequently, modelling terrestrial gravity perturbations in these detectors can focus on frequencies above 10 mHz.
This article is divided into six main sections. Section 2 serves as an introduction to gravity measurements focussing on the response mechanisms and basic properties of gravity sensors. Section 3 describes models of gravity perturbations from ambient seismic fields. The results can be used to estimate noise spectra at the surface and underground. A subsection is devoted to the problem of noise estimation in low-frequency GW detectors, which differs from high-frequency estimates mostly in that gravity perturbations are strongly correlated between different test masses. In the low-frequency regime, the gravity noise is best described as gravity-gradient noise. Section 4 is devoted to time domain models of transient gravity perturbations from seismic point sources. The formalism is applied to point forces and shear dislocations. The latter allows us to estimate gravity perturbations from earthquakes. Atmospheric models of gravity perturbations are presented in Section 5. This includes gravity perturbations from atmospheric temperature fields, infrasound fields, shock waves, and acoustic noise from turbulence. The solution for shock waves is calculated in time domain using the methods of Section 4. A theoretical framework to calculate gravity perturbations from objects is given in Section 6. Since many different types of objects can be potential sources of gravity perturbations, the discussion focusses on the development of a general method instead of summarizing all of the calculations that have been done in the past. Finally, Section 7 discusses possible passive and active noise mitigation strategies. Due to the complexity of the problem, most of the section is devoted to active noise cancellation providing the required analysis tools and showing limitations of this technique. Site selection is the main topic under passive mitigation, and is discussed in the context of reducing environmental noise and criteria relevant to active noise cancellation. Each of these sections ends with a summary and a discussion of open problems. While this article is meant to be a review of the current state of the field, it also presents new analyses especially with respect to the impact of seismic scattering on gravity perturbations (Sections 3.3.2 and 3.3.3), active gravity noise cancellation (Section 7.1.3), and timedomain models of gravity perturbations from atmospheric and seismic point sources (Sections 4.1, 4.5, and 5.3).
Even though evident to experts, it is worth emphasizing that all calculations carried out in this article have a common starting point, namely Newton’s universal law of gravitation. It states that the attractive gravitational force equation M1 between two point masses m1, m2 is given by
equation M21
where G = 6.672 × 10−11 N m2/kg2 is the gravitational constant. Eq. (1) gives rise to many complex phenomena on Earth such as inner-core oscillations [156], atmospheric gravity waves [157], ocean waves [94, 177], and co-seismic gravity changes [122]. Due to its importance, we will honor the eponym by referring to gravity noise as Newtonian noise in the following. It is thereby clarified that the gravity noise models considered in this article are non-relativistic, and propagation effects of gravity changes are neglected. While there could be interesting scenarios where this approximation is not fully justified (e.g., whenever a gravity perturbation can be sensed by several sensors and differences in arrival times can be resolved), it certainly holds in any of the problems discussed in this article. We now invite the reader to enjoy the rest of the article, and hope that it proves to be useful.

Gravity Measurements
In this section, we describe the relevant mechanisms by which a gravity sensor can couple to gravity perturbations, and give an overview of the most widely used measurement schemes: the (relative) gravimeter [53, 181], the gravity gradiometer [125], and the gravity strainmeter. The last category includes the large-scale GW detectors Virgo [6], LIGO [91], GEO600 [119], KAGRA [17], and a new generation of torsion-bar antennas currently under development [13]. Also atom interferometers can potentially be used as gravity strainmeters in the future [62]. Strictly speaking, none of the sensors only responds to a single field quantity (such as changes in gravity acceleration or gravity strain), but there is always a dominant response mechanism in each case, which justifies to give the sensor a specific name. A clear distinction between gravity gradiometers and gravity strainmeters has never been made to our knowledge. Therefore the sections on these two measurement principles will introduce a definition, and it is by no means the only possible one. Later on in this article, we almost exclusively discuss gravity models relevant to gravity strainmeters since the focus lies on gravity fluctuations above 10 mHz. Today, the sensitivity near 10 mHz of gravimeters towards gravity fluctuations is still competitive to or exceeds the sensitivity of gravity strainmeters, but this is likely going to change in the future so that we can expect strainmeters to become the technology of choice for gravity observations above 10 mHz [88]. The following sections provide further details on this statement. Space-borne gravity experiments such as GRACE [167] will not be included in this overview. The measurement principle of GRACE is similar to that of gravity strainmeters, but only very slow changes of Earth gravity field can be observed, and for this reason it is beyond the scope of this article.
The different response mechanisms to terrestrial gravity perturbations are summarized in Section 2.1. While we will identify the tidal forces acting on the test masses as dominant coupling mechanism, other couplings may well be relevant depending on the experiment. The Shapiro time delay will be discussed as the only relativistic effect. Higher-order relativistic effects are neglected. All other coupling mechanisms can be calculated using Newtonian theory including tidal forces, coupling in static non-uniform gravity fields, and coupling through ground displacement induced by gravity fluctuations. In Sections 2.2 to 2.4, the different measurement schemes are explained including a brief summary of the sensitivity limitations (choosing one of a few possible experimental realizations in each case). As mentioned before, we will mostly develop gravity models relevant to gravity strainmeters in the remainder of the article. Therefore, the detailed discussion of alternative gravimetry concepts mostly serves to highlight important differences between these concepts, and to develop a deeper understanding of the instruments and their role in gravity measurements.
Gravity response mechanisms
Gravity acceleration and tidal forces We will start with the simplest mechanism of all, the acceleration of a test mass in the gravity field. Instruments that measure the acceleration are called gravimeters. A test mass inside a gravimeter can be freely falling such as atom clouds [181] or, as suggested as possible future development, even macroscopic objects [72]. Typically though, test masses are supported mechanically or magnetically constraining motion in some of its degrees of freedom. A test mass suspended from strings responds to changes in the horizontal gravity acceleration. A test mass attached at the end of a cantilever with horizontal equilibrium position responds to changes in vertical gravity acceleration. The support fulfills two purposes. First, it counteracts the static gravitational force in a way that the test mass can respond to changes in the gravity field along a chosen degree of freedom. Second, it isolates the test mass from vibrations. Response to signals and isolation performance depend on frequency. If the support is modelled as a linear, harmonic oscillator, then the test mass response to gravity changes extends over all frequencies, but the response is strongly suppressed below the oscillators resonance frequency. The response function between the gravity perturbation δg(ω) and induced test mass acceleration δa(ω) assumes the form
equation M32
where we have introduced a viscous damping parameter γ, and ω0 is the resonance frequency. Well below resonance, the response is proportional to ω2, while it is constant well above resonance. Above resonance, the supported test mass responds like a freely falling mass, at least with respect to “soft” directions of the support. The test-mass response to vibrations δα(ω) of the support is given by
equation M43
This applies for example to horizontal vibrations of the suspension points of strings that hold a test mass, or to vertical vibrations of the clamps of a horizontal cantilever with attached test mass. Well above resonance, vibrations are suppressed by ω−2, while no vibration isolation is provided below resonance. The situation is somewhat more complicated in realistic models of the support especially due to internal modes of the mechanical system (see for example [76]), or due to coupling of degrees of freedom [121]. Large mechanical support structures can feature internal resonances at relatively low frequencies, which can interfere to some extent with the desired performance of the mechanical support [173]. While Eqs. (2) and (3) summarize the properties of isolation and response relevant for this paper, details of the readout method can fundamentally impact an instrument’s response to gravity fluctuations and its susceptibility to seismic noise, as explained in Sections 2.2 to 2.4.
Next, we discuss the response to tidal forces. In Newtonian theory, tidal forces cause a relative acceleration δg12(ω) between two freely falling test masses according to
equation M54
where equation M6 is the Fourier amplitude of the gravity potential. The last equation holds if the distance r12 between the test masses is sufficiently small, which also depends on the frequency. The term equation M7 is called gravity-gradient tensor. In Newtonian approximation, the second time integral of this tensor corresponds to gravity strain equation M8, which is discussed in more detail in Section 2.4. Its trace needs to vanish in empty space since the gravity potential fulfills the Poisson equation. Tidal forces produce the dominant signals in gravity gradiometers and gravity strainmeters, which measure the differential acceleration or associated relative displacement between two test masses (see Sections 2.3 and 2.4). If the test masses used for a tidal measurement are supported, then typically the supports are designed to be as similar as possible, so that the response in Eq. (2) holds for both test masses approximately with the same parameter values for the resonance frequencies (and to a lesser extent also for the damping). For the purpose of response calibration, it is less important to know the parameter values exactly if the signal is meant to be observed well above the resonance frequency where the response is approximately equal to 1 independent of the resonance frequency and damping (here, “well above” resonance also depends on the damping parameter, and in realistic models, the signal frequency also needs to be “well below” internal resonances of the mechanical support).
Shapiro time delay Another possible gravity response is through the Shapiro time delay [19]. This effect is not universally present in all gravity sensors, and depends on the readout mechanism. Today, the best sensitivities are achieved by reflecting laser beams from test masses in interferometric configurations. If the test mass is displaced by gravity fluctuations, then it imprints a phase shift onto the reflected laser, which can be observed in laser interferometers, or using phasemeters. We will give further details on this in Section 2.4. In Newtonian gravity, the acceleration of test masses is the only predicted response to gravity fluctuations. However, from general relativity we know that gravity also affects the propagation of light. The leading-order term is the Shapiro time delay, which produces a phase shift of the laser beam with respect to a laser propagating in flat space. It can be calculated from the weak-field spacetime metric (see chapter 18 in [124]):
equation M95
Here, c is the speed of light, ds is the so-called line element of a path in spacetime, and equation M10. Additionally, for this metric to hold, motion of particles in the source of the gravity potential responsible for changes of the gravity potential need to be much slower than the speed of light, and also stresses inside the source must be much smaller than its mass energy density. All conditions are fulfilled in the case of Earth gravity field. Light follows null geodesics with ds2 = 0. For the spacetime metric in Eq. (5), we can immediately write
equation M116
As we will find out, this equation can directly be used to calculate the time delay as an integral along a straight line in terms of the coordinates equation M12, but this is not immediately clear since light bends in a gravity field. So one may wonder if integration along the proper light path instead of a straight line yields additional significant corrections. The so-called geodesic equation must be used to calculate the path. It is a set of four differential equations, one for each coordinate t, equation M13 in terms of a parameter λ. The weak-field geodesic equation is obtained from the metric in Eq. (5):
equation M147
where we have made use of Eq. (6) and the slow-motion condition equation M15. The coordinates equation M16 are to be understood as functions of λ. Since the deviation of a straight path is due to a weak gravity potential, we can solve these equations by perturbation theory introducing expansions equation M17 and t = t(0) +t(1) + …. The superscript indicates the order in ψ/c2. The unperturbed path has the simple parametrization
equation M188
We have chosen integration constants such that unperturbed time t(0) and parameter λ can be used interchangeably (apart from a shift by t0). Inserting these expressions into the right-hand side of Eq. (7), we obtain
equation M199
As we can see, up to linear order in equation M20, the deviation equation M21 is in orthogonal direction to the unperturbed path equation M22, which means that the deviation can be neglected in the calculation of the time delay. After some transformations, it is possible to derive Eq. (6) from Eq. (9), and this time we find explicitly that the right-hand-side of the equation only depends on the unperturbed coordinates1. In other words, we can integrate the time delay along a straight line as defined in Eq. (8), and so the total phase integrated over a travel distance L is given by
equation M2310
In static gravity fields, the phase shift doubles if the light is sent back since not only the direction of integration changes, but also the sign of the expression substituted for dt/dλ.
Gravity induced ground motion As we will learn in Section 3, seismic fields produce gravity perturbations either through density fluctuations of the ground, or by displacing interfaces between two materials of different density. It is also well-known in seismology that seismic fields can be affected significantly by self-gravity. Self-gravity means that the gravity perturbation produced by a seismic field acts back on the seismic field. The effect is most significant at low frequency where gravity induced acceleration competes against acceleration from elastic forces. In seismology, low-frequency seismic fields are best described in terms of Earth’s normal modes [55]. Normal modes exist as toroidal modes and spheroidal modes. Spheroidal modes are influenced by self-gravity, toroidal modes are not. For example, predictions of frequencies and shapes of spheroidal modes based on Earth models such as PREM (Preliminary Reference Earth Model) [68] are inaccurate if self-gravity effects are excluded. What this practically means is that in addition to displacement amplitudes, gravity becomes a dynamical variable in the elastodynamic equations that determine the normal-mode properties. Therefore, seismic displacement and gravity perturbation cannot be separated in normal-mode formalism (although self-gravity can be neglected in calculations of spheroidal modes at sufficiently high frequency).
In certain situations, it is necessary or at least more intuitive to separate gravity from seismic fields. An exotic example is Earth’s response to GWs [67, 49, 47, 30, 48]. Another example is the seismic response to gravity perturbations produced by strong seismic events at large distance to the source as described in Section 4. It is more challenging to analyze this scenario using normal-mode formalism. The sum over all normal modes excited by the seismic event (each of which describing a global displacement field) must lead to destructive interference of seismic displacement at large distances (where seismic waves have not yet arrived), but not of the gravity amplitudes since gravity is immediately perturbed everywhere. It can be easier to first calculate the gravity perturbation from the seismic perturbation, and then to calculate the response of the seismic field to the gravity perturbation at larger distance. This method will be adopted in this section. Gravity fields will be represented as arbitrary force or tidal fields (detailed models are presented in later sections), and we simply calculate the response of the seismic field. Normal-mode formalism can be avoided only at sufficiently high frequencies where the curvature of Earth does not significantly influence the response (i.e., well above 10 mHz). In this section, we will model the ground as homogeneous half space, but also more complex geologies can in principle be assumed.
Gravity can be introduced in two ways into the elastodynamic equations, as a conservative force −∇ψ [146, 169], or as tidal strain The latter method was described first by Dyson to calculate Earth’s response to GWs [67]. The approach also works for Newtonian gravity, with the difference that the tidal field produced by a GW is necessarily a quadrupole field with only two degrees of freedom (polarizations), while tidal fields produced by terrestrial sources are less constrained. Certainly, GWs can only be fully described in the framework of general relativity, which means that their representation as a Newtonian tidal field cannot be used to explain all possible observations [124]. Nonetheless, important here is that Dyson’s method can be extended to Newtonian tidal fields. Without gravity, the elastodynamic equations for small seismic displacement can be written as
equation M2411
where equation M25 is the seismic displacement field, and equation M26 is the stress tensor [9]. In the absence of other forces, the stress is determined by the seismic field. In the case of a homogeneous and isotropic medium, the stress tensor for small seismic displacement can be written as
equation M2712
The quantity equation M28 is known as seismic strain tensor, and λ, μ are the Lamé constants (see Section 3.1). Its trace is equal to the divergence of the displacement field. Dyson introduced the tidal field from first principles using Lagrangian mechanics, but we can follow a simpler approach. Eq. (12) means that a stress field builds up in response to a seismic strain field, and the divergence of the stress field acts as a force producing seismic displacement. The same happens in response to a tidal field, which we represent as gravity strain equation M29. A strain field changes the distance between two freely falling test masses separated by equation M30 by equation M312. For sufficiently small distances L, the strain field can be substituted by the second time integral of the gravity-gradient tensor equation M32. If the masses are not freely falling, then the strain field acts as an additional force. The corresponding contribution to the material’s stress tensor can be written
equation M3313
Since we assume that the gravity field is produced by a distant source, the local contribution to gravity perturbations is neglected, which means that the gravity potential obeys the Laplace equation, equation M34. Calculating the divergence of the stress tensor according to Eq. (11), we find that the gravity term vanishes! This means that a homogeneous and isotropic medium does not respond to gravity strain fields. However, we have to be more careful here. Our goal is to calculate the response of a half-space to gravity strain. Even if the half-space is homogeneous, the Lamé constants change discontinuously across the surface. Hence, at the surface, the divergence of the stress tensor reads
equation M3514
In other words, tidal fields produce a force onto an elastic medium via gradients in the shear modulus (second Lamé constant). The gradient of the shear modulus can be written in terms of a Dirac delta function, equation M36, for a flat surface at z = 0 with unit normal vector equation M37. The response to gravity strain fields is obtained applying the boundary condition of vanishing surface traction, equation M38:
equation M3915
Once the seismic strain field is calculated, it can be used to obtain the seismic stress, which determines the displacement field equation M40 according to Eq. (11). In this way, one can for example calculate that a seismometer or gravimeter can observe GWs by monitoring surface displacement as was first calculated by Dyson [67].
Coupling in non-uniform, static gravity fields If the gravity field is static, but non-uniform, then displacement equation M41 of the test mass in this field due to a non-gravitational fluctuating force is associated with a changing gravity acceleration according to
equation M4216
We introduce a characteristic length λ, over which gravity acceleration varies significantly. Hence, we can rewrite the last equation in terms of the associated test-mass displacement ζ
equation M4317
where we have neglected directional dependence and numerical factors. The acceleration change from motion in static, inhomogeneous fields is generally more significant at low frequencies. Let us consider the specific case of a suspended test mass. It responds to fluctuations in horizontal gravity acceleration. The test mass follows the motion of the suspension point in vertical direction (i.e., no seismic isolation), while seismic noise in horizontal direction is suppressed according to Eq. (3). Accordingly, it is possible that the unsuppressed vertical (z-axis) seismic noise ξz(t) coupling into the horizontal (x-axis) motion of the test mass through the term ∂xgz = ∂zgx dominates over the gravity response term in Eq. (2). Due to additional coupling mechanisms between vertical and horizontal motion in real seismic-isolation systems, test masses especially in GW detectors are also isolated in vertical direction, but without achieving the same noise suppression as in horizontal direction. For example, the requirements on vertical test-mass displacement for Advanced LIGO are a factor 1000 less stringent than on the horizontal displacement [22]. Requirements can be set on the vertical isolation by estimating the coupling of vertical motion into horizontal motion, which needs to take the gravity-gradient coupling of Eq. (16) into account. Although, because of the frequency dependence, gravity-gradient effects are more significant in low-frequency detectors, such as the space-borne GW detector LISA [154].
Next, we calculate an estimate of gravity gradients in the vicinity of test masses in large-scale GW detectors, and see if the gravity-gradient coupling matters compared to mechanical vertical-to-horizontal coupling.
One contribution to gravity gradients will come from the vacuum chamber surrounding the test mass. We approximate the shape of the chamber as a hollow cylinder with open ends (open ends just to simplify the calculation). In our calculation, the test mass can be offset from the cylinder axis and be located at any distance to the cylinder ends (we refer to this coordinate as height). The gravity field can be expressed in terms of elliptic integrals, but the explicit solution is not of concern here. Instead, let us take a look at the results in Figure Figure1.1. Gravity gradients ∂zgx vanish if the test mass is located on the symmetry axis or at height L/2. There are also two additional ∂zgx = 0 contour lines starting at the symmetry axis at heights ∼ 0.24 and ∼0.76. Let us assume that the test mass is at height 0.3L, a distance 0.05L from the cylinder axis, the total mass of the cylinder is M = 5000 kg, and the cylinder height is L = 4 m. In this case, the gravity-gradient induced vertical-to-horizontal coupling factor at 20 Hz is
equation M4418
This means that gravity-gradient induced coupling is extremely weak, and lies well below estimates of mechanical coupling (of order 0.001 in Advanced LIGO3). Even though the vacuum chamber was modelled with a very simple shape, and additional asymmetries in the mass distribution around the test mass may increase gravity gradients, it still seems very unlikely that the coupling would be significant. As mentioned before, one certainly needs to pay more attention when calculating the coupling at lower frequencies. The best procedure is of course to have a 3D model of the near test-mass infrastructure available and to use it for a precise calculation of the gravity-gradient field.

The axes correspond to the distance of the test mass from the symmetry axis of the cylinder, and its height above one of the cylinders ends. The plot on the right is simply a zoom of the left plot into the intermediate heights.
Gravimeters
Gravimeters are instruments that measure the displacement of a test mass with respect to a non-inertial reference rigidly connected to the ground. The test mass is typically supported mechanically or magnetically (atom-interferometric gravimeters are an exception), which means that the test-mass response to gravity is altered with respect to a freely falling test mass. We will use Eq. (2) as a simplified response model. There are various possibilities to measure the displacement of a test mass. The most widespread displacement sensors are based on capacitive readout, as for example used in superconducting gravimeters (see Figure Figure22 and [96]). Sensitive displacement measurements are in principle also possible with optical readout systems; a method that is (necessarily) implemented in atom-interferometric gravimeters [137], and prototype seismometers [34] (we will explain the distinction between seismometers and gravimeters below). As will become clear in Section 2.4, optical readout is better suited for displacement measurements over long baselines, as required for the most sensitive gravity strain measurements, while the capacitive readout should be designed with the smallest possible distance between the test mass and the non-inertial reference [104].

Let us take a closer look at the basic measurement scheme of a superconducting gravimeter shown in Figure Figure2.2. The central part is formed by a spherical superconducting shell that is levitated by superconducting coils. Superconductivity provides stability of the measurement, and also avoids some forms of noise (see [96] for details). In this gravimeter design, the lower coil is responsible mostly to balance the mean gravitational force acting on the sphere, while the upper coil modifies the magnetic gradient such that a certain “spring constant” of the magnetic levitation is realized. In other words, the current in the upper coil determines the resonance frequency in Eq. (2).
Capacitor plates are distributed around the sphere. Whenever a force acts on the sphere, the small signal produced in the capacitive readout is used to immediately cancel this force by a feedback coil. In this way, the sphere is kept at a constant location with respect to the external frame. This illustrates a common concept in all gravimeters. The displacement sensors can only respond to relative displacement between a test mass and a surrounding structure. If small gravity fluctuations are to be measured, then it is not sufficient to realize low-noise readout systems, but also vibrations of the surrounding structure forming the reference frame must be as small as possible. In general, as we will further explore in the coming sections, gravity fluctuations are increasingly dominant with decreasing frequency. At about 1 mHz, gravity acceleration associated with fluctuating seismic fields become comparable to seismic acceleration, and also atmospheric gravity noise starts to be significant [53]. At higher frequencies, seismic acceleration is much stronger than typical gravity fluctuations, which means that the gravimeter effectively operates as a seismometer. In summary, at sufficiently low frequencies, the gravimeter senses gravity accelerations of the test mass with respect to a relatively quiet reference, while at higher frequencies, the gravimeter senses seismic accelerations of the reference with respect to a test mass subject to relatively small gravity fluctuations. In superconducting gravimeters, the third important contribution to the response is caused by vertical motion ξ(t) of a levitated sphere against a static gravity gradient (see Section 2.1.4). As explained above, feedback control suppresses relative motion between sphere and gravimeter frame, which causes the sphere to move as if attached to the frame or ground. In the presence of a static gravity gradient ∂zgz, the motion of the sphere against this gradient leads to a change in gravity, which alters the feedback force (and therefore the recorded signal). The full contribution from gravitational, δa(t), and seismic, equation M45, accelerations can therefore be written
equation M4619
It is easy to verify, using Eqs. (2) and (3), that the relative amplitude of gravity and seismic fluctuations from the first two terms is independent of the test-mass support. Therefore, vertical seismic displacement of the reference frame must be considered fundamental noise of gravimeters and can only be avoided by choosing a quiet measurement site. Obviously, Eq. (19) is based on a simplified support model. One of the important design goals of the mechanical support is to minimize additional noise due to non-linearities and cross-coupling. As is explained further in Section 2.3, it is also not possible to suppress seismic noise in gravimeters by subtracting the disturbance using data from a collocated seismometer. Doing so inevitably turns the gravimeter into a gravity gradiometer.
Gravimeters target signals that typically lie well below 1 mHz. Mechanical or magnetic supports of test masses have resonance frequencies at best slightly below 10 mHz along horizontal directions, and typically above 0.1 Hz in the vertical direction [23, 174]4. Well below resonance frequency, the response function can be approximated as equation M47. At first, it may look as if the gravimeter should not be sensitive to very low-frequency fluctuations since the response becomes very weak. However, the strength of gravity fluctuations also strongly increases with decreasing frequency, which compensates the small response. It is clear though that if the resonance frequency was sufficiently high, then the response would become so weak that the gravity signal would not stand out above other instrumental noise anymore. The test-mass support would be too stiff. The sensitivity of the gravimeter depends on the resonance frequency of the support and the intrinsic instrumental noise. With respect to seismic noise, the stiffness of the support has no influence as explained before (the test mass can also fall freely as in atom interferometers).
For superconducting gravimeters of the Global Geodynamics Project (GGP) [52], the median spectra are shown in Figure Figure3.3. Between 0.1 mHz and 1 mHz, atmospheric gravity perturbations typically dominate, while instrumental noise is the largest contribution between 1 mHz and 5 mHz [96]. The smallest signal amplitudes that have been measured by integrating long-duration signals is about 10−12 m/s2. A detailed study of noise in superconducting gravimeters over a larger frequency range can be found in [145]. Note that in some cases, it is not fit to categorize seismic and gravity fluctuations as noise and signal. For example, Earth’s spherical normal modes coherently excite seismic and gravity fluctuations, and the individual contributions in Eq. (19) have to be understood only to accurately translate data into normal-mode amplitudes [55].

Gravity gradiometers
It is not the purpose of this section to give a complete overview of the different gradiometer designs. Gradiometers find many practical applications, for example in navigation and resource exploration, often with the goal to measure static or slowly changing gravity gradients, which do not concern us here. For example, we will not discuss rotating gradiometers, and instead focus on gradiometers consisting of stationary test masses. While the former are ideally suited to measure static or slowly changing gravity gradients with high precision especially under noisy conditions, the latter design has advantages when measuring weak tidal fluctuations. In the following, we only refer to the stationary design. A gravity gradiometer measures the relative acceleration between two test masses each responding to fluctuations of the gravity field [102, 125]. The test masses have to be located close to each other so that the approximation in Eq. (4) holds. The proximity of the test masses is used here as the defining property of gradiometers. They are therefore a special type of gravity strainmeter (see Section 2.4), which denotes any type of instrument that measures relative gravitational acceleration (including the even more general concept of measuring space-time strain).
Gravity gradiometers can be realized in two versions. First, one can read out the position of two test masses with respect to the same rigid, non-inertial reference. The two channels, each of which can be considered a gravimeter, are subsequently subtracted. This scheme is for example realized in dual-sphere designs of superconducting gravity gradiometers [90] or in atom-interferometric gravity gradiometers [159].
It is schematically shown in Figure Figure4.4. Let us first consider the dual-sphere design of a superconducting gradiometer. If the reference is perfectly stiff, and if we assume as before that there are no cross-couplings between degrees of freedom and the response is linear, then the subtraction of the two gravity channels cancels all of the seismic noise, leaving only the instrumental noise and the differential gravity signal given by the second line of Eq. (4). Even in real setups, the reduction of seismic noise can be many orders of magnitude since the two spheres are close to each other, and the two readouts pick up (almost) the same seismic noise [125]. This does not mean though that gradiometers are necessarily more sensitive instruments to monitor gravity fields. A large part of the gravity signal (the common-mode part) is subtracted together with the seismic noise, and the challenge is now passed from finding a seismically quiet site to developing an instrument with lowest possible intrinsic noise.

Figure 4
Basic scheme of a gravity gradiometer for measurements along the vertical direction. Two test masses are supported by horizontal cantilevers (superconducting magnets, …). Acceleration of both test masses is measured against the same non-inertial reference frame, which is connected to the ground. Each measurement constitutes one gravimeter. Subtraction of the two channels yields a gravity gradiometer.
The atom-interferometric gradiometer differs in some important details from the superconducting gradiometer. The test masses are realized by ultracold atom clouds, which are (nearly) freely falling provided that magnetic shielding of the atoms is sufficient, and interaction between atoms can be neglected. Interactions of a pair of atom clouds with a laser beam constitute the basic gravity gradiometer scheme. Even though the test masses are freely falling, the readout is not generally immune to seismic noise [80, 18]. The laser beam interacting with the atom clouds originates from a source subject to seismic disturbances, and interacts with optics that require seismic isolation. Schemes have been proposed that could lead to a large reduction of seismic noise [178, 77], but their effectiveness has not been tested in experiments yet. Since the differential position (or tidal) measurement is performed using a laser beam, the natural application of atom-interferometer technology is as gravity strainmeter (as explained before, laser beams are favorable for differential position measurements over long baselines). Nonetheless, the technology is currently insufficiently developed to realize large-baseline experiments, and we can therefore focus on its application in gradiometry. Let us take a closer look at the response of atom-interferometric gradiometers to seismic noise. In atom-interferometric detectors (excluding the new schemes proposed in [178, 77]), one can show that seismic acceleration δα(ω) of the optics or laser source limits the sensitivity of a tidal measurement according to
equation M4820
where L is the separation of the two atom clouds, and is the speed of light. It should be emphasized that the seismic noise remains, even if all optics and the laser source are all linked to the same infinitely stiff frame. In addition to this noise term, other coupling mechanisms may play a role, which can however be suppressed by engineering efforts. The noise-reduction factor ωL/c needs to be compared with the common-mode suppression of seismic noise in superconducting gravity gradiometers, which depends on the stiffness of the instrument frame, and on contamination from cross coupling of degrees-of-freedom. While the seismic noise in Eq. (20) is a fundamental noise contribution in (conventional) atom-interferometric gradiometers, the noise suppression in superconducting gradiometers depends more strongly on the engineering effort (at least, we venture to claim that common-mode suppression achieved in current instrument designs is well below what is fundamentally possible).
To conclude this section, we discuss in more detail the connection between gravity gradiometers and seismically (actively or passively) isolated gravimeters. As we have explained in Section 2.2, the sensitivity limitation of gravimeters by seismic noise is independent of the mechanical support of the test mass (assuming an ideal, linear support). The main purpose of the mechanical support is to maximize the response of the test mass to gravity fluctuations, and thereby increase the signal with respect to instrumental noise other than seismic noise. Here we will explain that even a seismic isolation of the gravimeter cannot overcome this noise limitation, at least not without fundamentally changing its response to gravity fluctuations. Let us first consider the case of a passively seismically isolated gravimeter. For example, we can imagine that the gravimeter is suspended from the tip of a strong horizontal cantilever. The system can be modelled as two oscillators in a chain, with a light test mass m supported by a heavy mass M representing the gravimeter (reference) frame, which is itself supported from a point rigidly connected to Earth. The two supports are modelled as harmonic oscillators. As before, we neglect cross coupling between degrees of freedom. Linearizing the response of the gravimeter frame and test mass for small accelerations, and further neglecting terms proportional to m/M, one finds the gravimeter response to gravity fluctuations:
equation M4921
Here, ω1, γ1 are the resonance frequency and damping of the gravimeter support, while ω2, γ2 are the resonance frequency and damping of the test-mass support. The response and isolation functions R(·), S(·) are defined in Eqs. (2) and (3). Remember that Eq. (21) is obtained as a differential measurement of test-mass acceleration versus acceleration of the reference frame. Therefore, δg1(ω) denotes the gravity fluctuation at the center-of-mass of the gravimeter frame, and δg2(ω) at the test mass. An infinitely stiff gravimeter suspension, ω1 → ∞, yields R(ω; ω1, γ1) = 0, and the response turns into the form of the non-isolated gravimeter. The seismic isolation is determined by
equation M5022
We can summarize the last two equations as follows. At frequencies well above ω1, the seismically isolated gravimeter responds like a gravity gradiometer, and seismic noise is strongly suppressed. The deviation from the pure gradiometer response ∼ δg2(ω) − δg1(ω) is determined by the same function S(ω; ω1, γ1) that describes the seismic isolation. In other words, if the gravity gradient was negligible, then we ended up with the conventional gravimeter response, with signals suppressed by the seismic isolation function. Well below ω1, the seismically isolated gravimeter responds like a conventional gravimeter without seismic-noise reduction. If the centers of the masses m (test mass) and M (reference frame) coincide, and therefore δg1(ω) = δg2(ω), then the response is again like a conventional gravimeter, but this time suppressed by the isolation function S(ω; ω1, γ1).
Let us compare the passively isolated gravimeter with an actively isolated gravimeter. In active isolation, the idea is to place the gravimeter on a stiff platform whose orientation can be controlled by actuators. Without actuation, the platform simply follows local surface motion. There are two ways to realize an active isolation. One way is to place a seismometer next to the platform onto the ground, and use its data to subtract ground motion from the platform. The actuators cancel the seismic forces. This scheme is called feed-forward noise cancellation. Feed-forward cancellation of gravity noise is discussed at length in Section 7.1, which provides details on its implementation and limitations. The second possibility is to place the seismometer together with the gravimeter onto the platform, and to suppress seismic noise in a feedback configuration [4, 2]. In the following, we discuss the feed-forward technique as an example since it is easier to analyze (for example, feedback control can be unstable [4]). As before, we focus on gravity and seismic fluctuations. The seismometer’s intrinsic noise plays an important role in active isolation limiting its performance, but we are only interested in the modification of the gravimeter’s response. Since there is no fundamental difference in how a seismometer and a gravimeter respond to seismic and gravity fluctuations, we know from Section 2.2 that the seismometer output is proportional to δg1(ω) − δα(ω), i.e., using a single test mass for acceleration measurements, seismic and gravity perturbations contribute in the same way. A transfer function needs to be multiplied to the acceleration signals, which accounts for the mechanical support and possibly also electronic circuits involved in the seismometer readout. To cancel the seismic noise of the platform that carries the gravimeter, the effect of all transfer functions needs to be reversed by a matched feed-forward filter. The output of the filter is then equal to δg1(ω) − δα(ω) and is added to the motion of the platform using actuators cancelling the seismic noise and adding the seismometer’s gravity signal. In this case, the seismometer’s gravity signal takes the place of the seismic noise in Eq. (3). The complete gravity response of the actively isolated gravimeter then reads
equation M5123
The response is identical to a gravity gradiometer, where ω2, γ2 are the resonance frequency and damping of the gravimeter’s test-mass support. In reality, instrumental noise of the seismometer will limit the isolation performance and introduce additional noise into Eq. (23). Nonetheless, Eqs. (21) and (23) show that any form of seismic isolation turns a gravimeter into a gravity gradiometer at frequencies where seismic isolation is effective. For the passive seismic isolation, this means that the gravimeter responds like a gradiometer at frequencies well above the resonance frequency ω1 of the gravimeter support, while it behaves like a conventional gravimeter below ω1. From these results it is clear that the design of seismic isolations and the gravity response can in general not be treated independently. As we will see in Section 2.4 though, tidal measurements can profit strongly from seismic isolation especially when common-mode suppression of seismic noise like in gradiometers is insufficient or completely absent.
Gravity strainmeters
Gravity strain is an unusual concept in gravimetry that stems from our modern understanding of gravity in the framework of general relativity. From an observational point of view, it is not much different from elastic strain. Fluctuating gravity strain causes a change in distance between two freely falling test masses, while seismic or elastic strain causes a change in distance between two test masses bolted to an elastic medium. It should be emphasized though that we cannot always use this analogy to understand observations of gravity strain [106]. Fundamentally, gravity strain corresponds to a perturbation of the metric that determines the geometrical properties of spacetime [124]. We will briefly discuss GWs, before returning to a Newtonian description of gravity strain.
Gravitational waves are weak perturbations of spacetime propagating at the speed of light. Freely falling test masses change their distance in the field of a GW. When the length of the GW is much larger than the separation between the test masses, it is possible to interpret this change as if caused by a Newtonian force. We call this the long-wavelength regime. Since we are interested in the low-frequency response of gravity strainmeters throughout this article (i.e., frequencies well below 100 Hz), this condition is always fulfilled for Earth-bound experiments. The effect of a gravity-strain field equation M52 on a pair of test masses can then be represented as an equivalent Newtonian tidal field
equation M5324
Here, equation M54 is the relative acceleration between two freely falling test masses, L is the distance between them, and equation M55 is the unit vector pointing from one to the other test mass, and equation M56 its transpose. As can be seen, the gravity-strain field is represented by a 3 × 3 tensor. It contains the space-components of a 4-dimensional metric perturbation of spacetime, and determines all properties of GWs5. Note that the strain amplitude h in Eq. (24) needs to be multiplied by 2 to obtain the corresponding amplitude of the metric perturbation (e.g., the GW amplitude). Throughout this article, we define gravity strain as h = ΔL/L, while the effect of a GW with amplitude aGW on the separation of two test mass is determined by aGW = 2ΔL/L.
The strain field of a GW takes the form of a quadrupole oscillation with two possible polarizations commonly denoted × (cross)-polarization and +(plus)-polarization. The arrows in Figure Figure55 indicate the lines of the equivalent tidal field of Eq. (24).

Consequently, to (directly) observe GWs, one can follow two possible schemes: (1) the conventional method, which is a measurement of the relative displacement of suspended test masses typically carried out along two perpendicular baselines (arms); and (2) measurement of the relative rotation between two suspended bars. Figure Figure66 illustrates the two cases. In either case, the response of a gravity strainmeter is obtained by projecting the gravity strain tensor onto a combination of two unit vectors, equation M57 and equation M58, that characterize the orientation of the detector, such as the directions of two bars in a rotational gravity strain meter, or of two arms of a conventional gravity strain meter. This requires us to define two different gravity strain projections. The projection for the rotational strain measurement is given by
equation M5925
where the subscript × indicates that the detector responds to the ×-polarization assuming that the x, y-axes (see Figure Figure5)5) are oriented along two perpendicular bars. The vectors equation M60 and equation M61 are rotated counter-clockwise by 90° with respect to equation M62 and equation M63. In the case of perpendicular bars equation M64 and equation M65. The corresponding projection for the conventional gravity strain meter reads
equation M6626
The subscript + indicates that the detector responds to the +-polarization provided that the x, y-axes are oriented along two perpendicular baselines (arms) of the detector. The two schemes are shown in Figure Figure6.6. The most sensitive GW detectors are based on the conventional method, and distance between test masses is measured by means of laser interferometry. The LIGO and Virgo detectors have achieved strain sensitivities of better than 10−22 Hz−1/2 between about 50 Hz and 1000 Hz in past science runs and are currently being commissioned in their advanced configurations [91, 7]. The rotational scheme is realized in torsion-bar antennas, which are considered as possible technology for sub-Hz GW detection [155, 69]. However, with achieved strain sensitivity of about 10−8 Hz−1/2 near 0.1 Hz, the torsion-bar detectors are far from the sensitivity we expect to be necessary for GW detection [88].

Let us now return to the discussion of the previous sections on the role of seismic isolation and its impact on gravity response. Gravity strainmeters profit from seismic isolation more than gravimeters or gravity gradiometers. We have shown in Section 2.2 that seismically isolated gravimeters are effectively gravity gradiometers. So in this case, seismic isolation changes the response of the instrument in a fundamental way, and it does not make sense to talk of seismically isolated gravimeters. Seismic isolation could in principle be beneficial for gravity gradiometers (i.e., the acceleration of two test masses is measured with respect to a common rigid, seismically isolated reference frame), but the common-mode rejection of seismic noise (and gravity signals) due to the differential readout is typically so high that other instrumental noise becomes dominant. So it is possible that some gradiometers would profit from seismic isolation, but it is not generally true. Let us now consider the case of a gravity strainmeter. As explained in Section 2.3, we distinguish gradiometers and strainmeters by the distance of their test masses. For example, the distance of the LIGO or Virgo test masses is 4 km and 3 km respectively. Seismic noise and terrestrial gravity fluctuations are insignificantly correlated between the two test masses within the detectors’ most sensitive frequency band (above 10 Hz). Therefore, the approximation in Eq. (4) does not apply. Certainly, the distinction between gravity gradiometers and strainmeters remains somewhat arbitrary since at any frequency the approximation in Eq. (4) can hold for one type of gravity fluctuation, while it does not hold for another. Let us adopt a more practical definition at this point. Whenever the design of the instrument places the test masses as distant as possible from each other given current technology, then we call such an instrument strainmeter. In the following, we will discuss seismic isolation and gravity response for three strainmeter designs, the laser-interferometric, atom-interferometric, and superconducting strainmeters. It should be emphasized that the atom-interferometric and superconducting concepts are still in the beginning of their development and have not been realized yet with scientifically interesting sensitivities.
Laser-interferometric strainmeters The most sensitive gravity strainmeters, namely the large-scale GW detectors, use laser interferometry to read out the relative displacement between mirror pairs forming the test masses. Each test mass in these detectors is suspended from a seismically isolated platform, with the suspension itself providing additional seismic isolation. Section 2.1.1 introduced a simplified response and isolation model based on a harmonic oscillator characterized by a resonance frequency ω0 and viscous damping γ6. In a multi-stage isolation and suspension system as realized in GW detectors (see for example [37, 121]), coupling between multiple oscillators cannot be neglected, and is fundamental to the seismic isolation performance, but the basic features can still be explained with the simplified isolation and response model of Eqs. (2) and (3). The signal output of the interferometer is proportional to the relative displacement between test masses. Since seismic noise is approximately uncorrelated between two distant test masses, the differential measurement itself cannot reject seismic noise as in gravity gradiometers. Without seismic isolation, the dominant signal would be seismic strain, i.e., the distance change between test masses due to elastic deformation of the ground, with a value of about 10−15 Hz−1/2 at 50 Hz (assuming kilometer-scale arm lengths). At the same time, without seismically isolated test masses, the gravity signal can only come from the ground response to gravity fluctuations as described in Section 2.1.3, and from the Shapiro time delay as described in Section 2.1.2.

Kathmandu (/ˌkætmænˈduː/;[2] Nepali: काठमाडौँ, Nepali pronunciation: [ˈkaʈʰmaɳɖu]) is the capital and largest city of Nepal, with a population of around 1 million. Also known as the city of temples, the city stands at an elevation of approximately 1,400 metres (4,600 feet) above sea level in the bowl-shaped Kathmandu valley in central Nepal. The valley was historically called the "Nepal Mandala" and has been the home of the Newar people, a cosmopolitan urban civilization in the Himalayan foothills. The city was the royal capital of the Kingdom of Nepal and hosts palaces, mansions and gardens of the Nepalese aristocracy. It has been home to the headquarters of the South Asian Association for Regional Cooperation (SAARC) since 1985. Today, it is the seat of government of the Nepalese republic, established in 2008, and is part of the Bagmati Province.
Kathmandu is and has been for many years the centre of Nepal's history, art, culture, and economy. It has a multi-ethnic population within a Hindu and Buddhist majority. Religious and cultural festivities form a major part of the lives of people residing in Kathmandu. Tourism is an important part of the economy in the city. In 2013, Kathmandu was ranked third among the top ten upcoming travel destinations in the world by TripAdvisor, and ranked first in Asia. The city is considered the gateway to the Nepalese Himalayas and is home to several world heritage sites: the Durbar Square, Swayambhunath, Boudhanath and Pashupatinath. Kathmandu valley is growing at 4 percentange per year according to the World Bank in 2010, making it one of the fastest-growing metropolitan areas in South Asia, and the first region in Nepal to face the unprecedented challenges of rapid urbanization and modernization at a metropolitan scale.
Historic areas of Kathmandu were severely damaged by a 7.8 magnitude earthquake in April 2015. Some of the buildings have been restored while some remain in the process of reconstruction.
Etymology
The indigenous Newari term for Kathmandu valley is Yen. The Nepali name Kathmandu comes from Kasthamandap, which stood in the Durbar Square. In Sanskrit, Kāṣṭha (Sanskrit: काष्ठ) means "Wood" and Maṇḍapa (Sanskrit: मण्डप) means "Pavilion". This public pavilion, also known as Maru Satta in Newari, was rebuilt in 1596 by Biseth in the period of King Laxmi Narsingh Malla. The three-storey structure was made entirely of wood and used no iron nails nor supports. According to legends, all the timber used to build the pagoda was obtained from a single tree.[4] The structure collapsed during a major earthquake in April 2015.
The colophons of ancient manuscripts, dated as late as the 20th century, refer to Kathmandu as Kāṣṭhamaṇḍap Mahānagar in Nepal Mandala. Mahānagar means "great city". The city is called Kāṣṭhamaṇḍap in a vow that Buddhist priests still recite to this day. Thus, Kathmandu is also known as Kāṣṭhamaṇḍap. During medieval times, the city was sometimes called Kāntipur (Sanskrit: कान्तिपुर). This name is derived from two Sanskrit words – Kānti and Pur. Kānti is a word that stands for "beauty" and is mostly associated with light and Pur means place, thus giving it the meaning, "City of light".
Among the indigenous Newar people, Kathmandu is known as Yeṃ Deśa (Nepal Bhasa: येँ देश), and Patan and Bhaktapur are known as Yala Deśa (Nepal Bhasa: यल देश) and Khwopa Deśa (Nepal Bhasa: ख्वप देश) respectively.[5] "Yen" is the shorter form of Yambu (Nepal Bhasa: यम्बु), which originally referred to the northern half of Kathmandu. The older northern settlements were referred to as Yambi while the southern settlement was known as Yangala.[6][7]
The spelling "Katmandu" was often used in older English-language text. More recently, however, the spelling "Kathmandu" has become more common in English.
History
Archaeological excavations in parts of Kathmandu have found evidence of ancient civilizations. The oldest of these findings is a statue, found in Maligaon, that was dated at 185 AD.[9] The excavation of Dhando Chaitya uncovered a brick with an inscription in Brahmi script. Archaeologists believe it is two thousand years old.[9] Stone inscriptions are a ubiquitous element at heritage sites and are key sources for the history of Nepal.
The earliest Western reference to Kathmandu appears in an account of Jesuit Fathers the Portuguese Jesuit, Fr. Joao Cabral who passed through the Kathmandu Valley in the spring of 1628 [10]and was received graciously by the king of that time, probably King Lakshminarasimha Malla of Kathmandu on their way from Tibet to India,[11] and reported that they reached "Cadmendu", the capital of Nepal kingdom.[12]
Ancient history
The ancient history of Kathmandu is described in its traditional myths and legends. According to Swayambhu Purana, present-day Kathmandu was once a huge and deep lake named "Nagdaha", as it was full of snakes. The lake was cut drained by Bodhisatwa Manjushree with his sword, and the water was evacuated out from there. He then established a city called Manjupattan, and made Dharmakar the ruler of the valley land. After some time, a demon named Banasur closed the outlet, and the valley again turned into a lake. Then Lord Krishna came to Nepal, killed Banasur, and again drained out the water. He brought some Gopals along with him and made Bhuktaman the king of Nepal.[13][14][15]
Kotirudra Samhita of Shiva Purana, Chapter 11, Shloka 18 refers to the place as Nayapala city, which was famous for its Pashupati Shivalinga. The name Nepal probably originates from this city Nayapala.
Very few historical records exists of the period before medieval Licchavi rulers. According to Gopalraj Vansawali, a genealogy of Nepali monarchy, the rulers of Kathmandu Valley before the Licchavis were Gopalas, Mahispalas, Aabhirs, Kiratas, and Somavanshi.[15][16] The Kirata dynasty was established by Yalamber. During the Kirata era, a settlement called Yambu existed in the northern half of old Kathmandu. In some of the Sino-Tibetan languages, Kathmandu is still called Yambu. Another smaller settlement called Yengal was present in the southern half of old Kathmandu, near Manjupattan. During the reign of the seventh Kirata ruler, Jitedasti, Buddhist monks entered Kathmandu valley and established a forest monastery at Sankhu.

Licchavi era
The Licchavis from the Indo-Gangetic plain migrated north and defeated the Kiratas, establishing the Licchavi dynasty, circa 400 AD. During this era, following the genocide of Shakyas in Lumbini by Virudhaka, the survivors migrated north and entered the forest monastery lora masquerading as Koliyas. From Sankhu, they migrated to Yambu and Yengal (Lanjagwal and Manjupattan) and established the first permanent Buddhist monasteries of Kathmandu. This created the basis of Newar Buddhism, which is the only surviving Sanskrit-based Buddhist tradition in the world.[17] With their migration, Yambu was called Koligram and Yengal was called Dakshin Koligram[18] during most of the Licchavi era.[19]
Eventually, the Licchavi ruler Gunakamadeva merged Koligram and Dakshin Koligram, founding the city of Kathmandu.[19] The city was designed in the shape of Chandrahrasa, the sword of Manjushri. The city was surrounded by eight barracks guarded by Ajimas. One of these barracks is still in use at Bhadrakali (in front of Singha Durbar). The city served as an important transit point in the trade between India and Tibet, leading to tremendous growth in architecture. Descriptions of buildings such as Managriha, Kailaskut Bhawan, and Bhadradiwas Bhawan have been found in the surviving journals of travellers and monks who lived during this era. For example, the famous 7th-century Chinese traveller Xuanzang described Kailaskut Bhawan, the palace of the Licchavi king Amshuverma.[20] The trade route also led to cultural exchange as well. The artistry of the Newar people—the indigenous inhabitants of the Kathmandu Valley—became highly sought after during this era, both within the Valley and throughout the greater Himalayas. Newar artists travelled extensively throughout Asia, creating religious art for their neighbours. For example, Araniko led a group of his compatriot artists through Tibet and China. Bhrikuti, the princess of Nepal who married Tibetan monarch Songtsän Gampo, was instrumental in introducing Buddhism to Tibet.

Malla era
The Licchavi era was followed by the Malla era. Rulers from Tirhut, upon being attacked by Muslims, fled north to the Kathmandu valley. They intermarried with Nepali royalty, and this led to the Malla era. The early years of the Malla era were turbulent, with raids and attacks from Khas and Turk Muslims. There was also a devastating earthquake which claimed the lives of a third of Kathmandu's population, including the king Abhaya Malla. These disasters led to the destruction of most of the architecture of the Licchavi era (such as Mangriha and Kailashkut Bhawan), and the loss of literature collected in various monasteries within the city. Despite the initial hardships, Kathmandu rose to prominence again and, during most of the Malla era, dominated the trade between India and Tibet. Nepali currency became the standard currency in trans-Himalayan trade.
During the later part of the Malla era, Kathmandu Valley comprised four fortified cities: Kantipur, Lalitpur, Bhaktapur, and Kirtipur. These served as the capitals of the Malla confederation of Nepal. These states competed with each other in the arts, architecture, esthetics, and trade, resulting in tremendous development. The kings of this period directly influenced or involved themselves in the construction of public buildings, squares, and temples, as well as the development of waterspouts, the institutionalisation of trusts (called guthis), the codification of laws, the writing of dramas, and the performance of plays in city squares. Evidence of an influx of ideas from India, Tibet, China, Persia, and Europe among other places can be found in a stone inscription from the time of king Pratap Malla. Books have been found from this era that describe their tantric tradition (e.g. Tantrakhyan), medicine (e.g. Haramekhala), religion (e.g. Mooldevshashidev), law, morals, and history. Amarkosh, a Sanskrit-Nepal Bhasa dictionary from 1381 AD, was also found. Architecturally notable buildings from this era include Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, the former durbar of Kirtipur, Nyatapola, Kumbheshwar, the Krishna temple, and others.
Medieval era
The Gorkha Kingdom ended the Malla confederation after the Battle of Kathmandu in 1768. This marked the beginning of the modern era in Kathmandu. The Battle of Kirtipur was the start of the Gorkha conquest of the Kathmandu Valley. Kathmandu was adopted as the capital of the Gorkha empire, and the empire itself was dubbed Nepal. During the early part of this era, Kathmandu maintained its distinctive culture. Buildings with characteristic Nepali architecture, such as the nine-story tower of Basantapur, were built during this era. However, trade declined because of continual war with neighbouring nations. Bhimsen Thapa supported France against Great Britain; this led to the development of modern military structures, such as modern barracks in Kathmandu. The nine-storey tower Dharahara was originally built during this era.
Rana rule
Rana rule over Nepal started with the Kot Massacre of 1846, which occurred near Hanuman Dhoka Durbar. During this massacre, most of Nepal's high-ranking officials were massacred by Jung Bahadur Rana and his supporters. Another massacre, the Bhandarkhal Massacre, was also conducted by Kunwar and his supporters in Kathmandu. During the Rana regime, Kathmandu's alliance shifted from anti-British to pro-British; this led to the construction of the first buildings in the style of Western European architecture. The most well-known of these buildings include Singha Durbar, Garden of Dreams, Shital Niwas, and the old Narayanhiti palace. The first modern commercial road in the Kathmandu Valley, the New Road, was also built during this era. Trichandra College (the first college of Nepal), Durbar High School (the first modern school of Nepal), and Bir Hospital (the first hospital of Nepal) were built in Kathmandu during this era. Education was only accessible to the privileged class. Rana rule was marked by despotism, economic exploitation and religious persecution.
Geography
Kathmandu is in the northwestern part of the Kathmandu Valley to the north of the Bagmati river and covers an area of 50.7 km2 (19.6 sq mi). The average elevation is 1,400 metres (4,600 ft) above sea level.[23] The city is bounded by several other municipalities of the Kathmandu valley: south of the Bagmati by Lalitpur Metropolitan City (Patan), with which it forms one urban area surrounded by a ring road, to the southwest by Kirtipur and to the east by Madyapur Thimi. To the north the urban area extends into several municipalities; Nagarjun, Tarakeshwor, Tokha, Budhanilkantha, Gokarneshwor and Kageshwori Manohara. However, the urban agglomeration extends well beyond the neighbouring municipalities, e.g. to Bhaktapur, and nearly covers the entire Kathmandu valley.
Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumante Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,500–3,000 metres (4,900–9,800 ft), and have passes which provide access to and from Kathmandu and its valley.[24][25][26] An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.
The city of Kathmandu and the surrounding valley are in the Deciduous Monsoon Forest Zone (altitude range of 1,200–2,100 metres (3,900–6,900 ft)), one of five vegetation zones defined for Nepal. The dominant tree species in this zone are oak, elm, beech, maple and others, with coniferous trees at higher altitude.[27]

Kathmandu administration
Kathmandu and adjacent cities are composed of neighbourhoods, which are utilized quite extensively and more familiar among locals. However, administratively the city is divided into 32 wards, numbered from 1 to 32. Earlier, there were 35 wards which made it the metropolitan city with the largest number of the wards.[28]
Kathmandu agglomeration
There is no officially defined agglomeration of Kathmandu. The urban area of the Kathmandu valley is split among three different districts (second level of administrative divisions within a province), which extend very little beyond the valley fringe, except towards the southern ranges, which have a comparatively small population.[29] They have the three highest population densities in the country. These 3 districts are administered by 21 local level bodies; 2 metropolitan cities (Kathmandu and Lalitpur), 16 municipalities and 3 rural municipalities. Imperial conversion
Five major climatic regions are found in Nepal. Of these, Kathmandu Valley is in the Warm Temperate Zone (elevation ranging from 1,200 to 2,300 metres (3,900 to 7,500 ft)), where the climate is fairly temperate, atypical for the region. This zone is followed by the Cool Temperate Zone with elevation varying between 2,100 and 3,300 metres (6,900 and 10,800 ft). Under Köppen's climate classification, portions of the city with lower elevations have a humid subtropical climate (Cwa), while portions of the city with higher elevations generally have a subtropical highland climate (Cwb). In the Kathmandu Valley, which is representative of its valley's climate, the average summer temperature varies from 28 to 30 °C (82 to 86 °F). The average winter temperature is 10.1 °C (50.2 °F).
The city generally has a climate with warm days followed by cool nights and mornings. Unpredictable weather is expected, given that temperatures can drop to 1 °C (34 °F) or less during the winter. During a 2013 cold front, the winter temperatures of Kathmandu dropped to −4 °C (25 °F), and the lowest temperature was recorded on 10 January 2013, at −9.2 °C (15.4 °F). Rainfall is mostly monsoon-based (about 65% of the total concentrated during the monsoon months of June to September), and decreases substantially (100 to 200 cm (39 to 79 in)) from eastern Nepal to western Nepal. Rainfall has been recorded at about 1,400 millimetres (55.1 in) for the Kathmandu valley, and averages 1,407 millimetres (55.4 in) for the city of Kathmandu. On average humidity is 75%.[24][30][31] The chart below is based on data from the Nepal Bureau of Standards & Meteorology, Weather Meteorology for 2005. The chart provides minimum and maximum temperatures during each month. The annual amount of precipitation was 1,124 millimetres (44.3 in) for 2005, as per monthly data included in the table above.[31] The decade of 2000–2010 saw highly variable and unprecedented precipitation anomalies in Kathmandu. This was mostly due to the annual variation of the southwest monsoon.[citation needed] For example, 2001 recorded only 356 mm (14 in) of precipitation due to an extraordinarily weak monsoon season. In contrast, 2003 was the wettest year ever in Kathmandu, totaling over 2,900 mm (114 in) of precipitation due to an exceptionally strong monsoon season.
Air quality
Air pollution is a major issue in the Kathmandu Valley.[36][37][38] According to the 2016 World Health Organization's Ambient Air Pollution Database,[39] the annual average PM2.5 (particulate matter) concentration in 2013 was 49 μg/m3, which is 4.9 times higher than recommended by the World Health Organization.[40][41] Starting in early 2017, the Government of Nepal and the Embassy of the United States in Kathmandu have monitored and publicly share real-time air quality data. In Nepal and Kathmandu, the annual premature deaths due to air pollution reached 37,399 and 9,943 respectively, according to a Republica news report published on 23 November, 2019. This indicates, around a quarter of the total deaths due to air pollution in Nepal are in Kathmandu.
Government and public services
Kathmandu Municipal Corporation (KMC) is the chief nodal agency for the administration of Kathmandu. The Municipality of Kathmandu was upgraded to a metropolitan city in 1995.
Metropolitan Kathmandu is divided into five sectors: the Central Sector, the East Sector, the North Sector, the City Core and the West Sector. For civic administration, the city is further divided into 35 administrative wards. The Council administers the Metropolitan area of Kathmandu city through its 177 elected representatives and 20 nominated members. It holds biannual meetings to review, process and approve the annual budget and make major policy decisions.[24][44] The ward's profile documents for the 35 wards prepared by the Kathmandu Metropolitan Council is detailed and provides information for each ward on population, the structure and condition of houses, the type of roads, educational, health and financial institutions, entertainment facilities, parking space, security provisions, etc. It also includes lists of development projects completed, on-going and planned, along with informative data about the cultural heritage, festivals, historical sites and the local inhabitants. Ward 16 is the largest, with an area of 437.4 ha; ward 26 is the smallest, with an area of 4 ha.[45]
Kathmandu is the headquarters of the surrounding Kathmandu district. The city of Kathmandu forms this district along with 10 other municipalities, namely Budanilkantha, Chandragiri, Dakshinkali, Gokarneshwar, Kageshwari Manohara, Kirtipur, Nagarjun, Shankharapur, Tarakeshwar and Tokha.
Law and order
The Metropolitan Police is the main law enforcement agency in the city. It is headed by a commissioner of police. The Metropolitan Police is a division of the Nepal Police, and the administrative control lies with the Ministry of Home Affairs.

Fire service
The fire service, known as the Barun Yantra Karyalaya (Nepali: वारुण यन्त्र कार्यालय), opened its first station in Kathmandu in 1937 with a single-vehicle.[46] An iron tower was erected to monitor the city and watch for a fire. As a precautionary measure, firemen were sent to the areas which were designated as accident-prone areas.[46] In 1944, the fire service was extended to the neighbouring cities of Lalitpur and Bhaktapur. In 1966, a fire service was established in Kathmandu central airport.[46] In 1975, a West German government donation added seven fire engines to Kathmandu's fire service.[46] The fire service in the city is also overlooked by an international non-governmental organization, the Firefighters Volunteer Association of Nepal (FAN), which was established in 2000 with the purpose of raising public awareness about fire and improving safety.[46]
Electricity and water supply
Public baths, Kathmandu. 1979
Electricity in Kathmandu is regulated and distributed by the Nepal Electricity Authority (NEA). Water supply and sanitation facilities are provided by the Kathmandu Upatyaka Khanepani Limited (KUKL). There is a severe shortage of water for household purposes such as drinking, bathing, cooking and washing and irrigation. People have been using bottled mineral water, water from tank trucks and from the ancient dhunge dharas (Nepali: ढुङ्गे धारा) for all the purposes related to water. The city water shortage should be solved by the completion of the much plagued Melamchi Water Supply Project by the end of 2019.[47][48]
Waste management
Waste management may be through composting in municipal waste management units, and at houses with home composting units. Both systems are common and established in India and neighbouring countries.[49]
Demographics
Kathmandu's urban cosmopolitan character has made it the most populous city in Nepal, recording a population of 671,846 residents living in 235,387 households in the metropolitan area, according to the 2001 census.[50] According to the National Population Census of 2011, the total population of Kathmandu city was 975,543 with an annual growth rate of 6.12% with respect to the population figure of 2001. 70% of the total population residing in Kathmandu are aged between 15 and 59.
Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of 5,076.6 hectares (12,545 acres) has expanded to 8,214 hectares (20,300 acres) in 2001. With this new area, the population density which was 85 in 1991 remained 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.[51]
Currently based on various data Kathmandu population is 1,442,300 with population density of 29,166.835 per sq.km making it as 6th densely populated city in the world.
Ethnic groups
The largest ethnic groups residing in Kathmandu Metropolitan City consists of primarily various caste groups of the Newar community at 25%, Hill Janajati/Adivisis like Tamang, Kirat, Gurung, Magar, Sherpa, etc. making~20%, Khas Brahmin at 24%, Khas Chhetri at 20%, and 7% Terai groups including Madhesi castes and Terai Janajatis/Adivasis like Tharus.[52] More recently, other hill ethnic groups and caste groups from Terai have come to represent a substantial proportion of the city's population. The major languages are Nepali and Nepal Bhasa, while English is understood by many, particularly in the service industry. According to data from 2011, the major religions in Kathmandu city are Hinduism 81.3%, Buddhism 9%, Islam 4.4% and other 5.2%.[53]
The linguistic profile of Kathmandu underwent drastic changes during the Shah dynasty's rule because of its strong bias towards the Hindu culture. Sanskrit language therefore was preferred and people were encouraged to learn it even by attending Sanskrit learning centres in Terai. Sanskrit schools were specially set up in Kathmandu and in the Terai region to inculcate traditional Hindu culture and practices originated from Nepal.[54]
Architecture and cityscape
The ancient trade route between India and Tibet that passed through Kathmandu enabled a fusion of artistic and architectural traditions from other cultures to be amalgamated with local art and architecture.[56] The monuments of Kathmandu City have been influenced over the centuries by Hindu and Buddhist religious practices. The architectural treasure of the Kathmandu valley has been categorized under the well-known seven groups of heritage monuments and buildings. In 2006 UNESCO declared these seven groups of monuments as a World Heritage Site (WHS). The seven monuments zones cover an area of 189 hectares (470 acres), with the buffer zone extending to 2,394 hectares (5,920 acres). The Seven Monument Zones inscribed originally in 1979 and with a minor modification in 2006 are the Durbar squares of Hanuman Dhoka, Patan and Bhaktapur, the Hindu temples of Pashupatinath and Changunarayan, the Buddhist stupas of Swayambhunath and Boudhanath.[57][58]
Durbar Squares
Main articles: Kathmandu Durbar Square and Hanuman Dhoka
The literal meaning of Durbar Square is a "place of palaces." There are three preserved Durbar Squares in Kathmandu valley and one unpreserved in Kirtipur. The Durbar Square of Kathmandu is in the old city and has heritage buildings representing four kingdoms (Kantipur, Lalitpur, Bhaktapur, Kirtipur); the earliest being the Licchavi dynasty. The complex has 50 temples and is distributed in two quadrangles of the Durbar Square. The outer quadrangle has the Kasthamandap, Kumari Ghar, and Shiva-Parvati Temple; the inner quadrangle has the Hanuman Dhoka palace. The squares were severely damaged in the April 2015 earthquake.
Hanuman Dhoka is a complex of structures with the royal palace of the Malla kings and of the Shah dynasty. It is spread over five acres. The eastern wing, with ten courtyards, is the oldest part, dating to the mid-16th century. It was expanded by King Pratap Malla in the 17th century with many temples. The royal family lived in this palace until 1886 when they moved to Narayanhiti Palace. The stone inscription outside is in fifteen languages.
Kumari Ghar is a palace in the centre of the Kathmandu city, next to the Durbar square where a royal Kumari selected from several Kumaris resides. Kumari, or Kumari Devi, is the tradition of worshipping young pre-pubescent girls as manifestations of the divine female energy or devi in South Asian countries. In Nepal the selection process is very rigorous. Previously, during the time of the monarchy, the queen and the priests used to appoint the proposed Kumari with delicate process of astrological examination and physical examination of 32 'gunas'. The china (Nepali: चिना), an ancient Hindu astrological report, of the Kumari and the reigning king, was ought to be similar. The Kumari is believed to be a bodily incarnation of the goddess Taleju (the Nepali name for Durga) until she menstruates, after which it is believed that the goddess vacates her body. Serious illness or a major loss of blood from an injury also causes her to revert to common status. The current Kumari, Trishna Shakya, age three at the time of appointment, was installed in September 2017 succeeding Matina Shakya who was the first Kumari of Kathmandu after the end of the monarchy.[59]
Kasthamandap is a three-storeyed temple enshrining an image of Gorakhnath. It was built in the 16th century in pagoda style. The name of Kathmandu is a derivative of the word Kasthamandap. It was built under the reign of King Laxmi Narsingha Malla. Kasthamandap stands at the intersection of two ancient trade routes linking India and Tibet at Maru square. It was originally built as a rest house for travellers.

The Pashupatinath Temple (Nepali: पशुपतिनाथ मन्दिर) is a famous 5th century Hindu temple dedicated to Lord Shiva. Located on the banks of the Bagmati river, the Pashupatinath Temple is the oldest Hindu temple in Kathmandu.[60] It served as the seat of national deity, Lord Pashupatinath, until Nepal was secularized. However, a significant part of the temple was destroyed by Mughal invaders in the 14th century and little or nothing remains of the original 5th-century temple exterior. The temple as it stands today was built in the 19th century, although the image of the bull and the black four-headed image of Pashupati are at least 300 years old.[61] The temple is a UNESCO World Heritage Site.[61][62] Shivaratri, or the night of Lord Shiva, is the most important festival that takes place here, attracting thousands of devotees and sadhus.[citation needed]
Believers in Pashupatinath (mainly Hindus) are allowed to enter the temple premises, but non-Hindu visitors are allowed to view the temple only from the across the Bagmati River.[61] The priests who perform the services at this temple have been Brahmins from Karnataka in southern India since the time of Malla king Yaksha Malla.[63] This tradition is believed to have been started at the request of Adi Shankaracharya who sought to unify the states of Bharatam, a region in south Asia believed to be ruled by a mythological king Bharat, by encouraging cultural exchange. This procedure is followed in other temples around India, which were sanctified by Adi Shankaracharya.
The temple is built in the pagoda style of architecture, with cubic constructions and carved wooden rafters (tundal) on which they rest, and two-level roofs made of copper and gold.
Boudhanath
Boudhanath (Nepali: बौद्ध स्तुप; also written as Bouddhanath, Bodhnath, Baudhanath or the Khāsa Chaitya), is one of the holiest Buddhist sites in Nepal, along with the Swayambhunath. It is a very popular tourist site. Boudhanath is known as Khāsti by Newars and as Bauddha or Bodhnāth by speakers of Nepali.[64] About 11 km (7 mi) from the centre and northeastern outskirts of Kathmandu, the stupa's massive mandala makes it one of the largest spherical stupas in Nepal.[65] Boudhanath became a UNESCO World Heritage Site in 1979.
The base of the stupa has 108 small depictions of the Dhyani Buddha Amitabha. It is surrounded with a brick wall with 147 niches, each with four or five prayer wheels engraved with the mantra, om mani padme hum.[66] At the northern entrance where visitors must pass is a shrine dedicated to Ajima, the goddess of smallpox.[66] Every year the stupa attracts many Tibetan Buddhist pilgrims who perform full body prostrations in the inner lower enclosure, walk around the stupa with prayer wheels, chant, and pray.[66] Thousands of prayer flags are hoisted up from the top of the stupa downwards and dot the perimeter of the complex. The influx of many Tibetan refugees from China has seen the construction of over 50 Tibetan gompas (monasteries) around Boudhanath.
Swayambhu
Main article: Swayambhunath
Swayambhunath (Nepali: स्वयम्भू स्तूप) is a Buddhist stupa atop a hillock at the northwestern part of the city. This is among the oldest religious sites in Nepal. Although the site is considered Buddhist, it is revered by both Buddhists and Hindus. The stupa consists of a dome at the base; above the dome, there is a cubic structure with the eyes of Buddha looking in all four directions.[clarification needed] There are pentagonal toran above each of the four sides, with statues engraved on them. Behind and above the torana there are thirteen tiers. Above all the tiers, there is a small space above which lies a gajur.
Rani Pokhari
Main article: Ranipokhari
Ranipokhari (Nepali: रानी पोखरी, lit. 'Queen's Pond') is a historic artificial pond nestled in the heart of Kathmandu. It was built by king Pratap Malla in 1670 AD for his beloved queen after she lost her son and could not recover from her loss.[67] A large stone statue of an elephant in the south signifies the image of Pratap Malla and his two sons. Balgopaleshwor Temple stands still inside the temple above the pond. Rani Pokhari is opened once a year during the final day of Tihar i.e. Bhai Tika and Chhath festival. The world's largest Chhath takes place every year in Ranipokhari. The pond is one of Kathmandu's most famous landmarks and is known for its religious and aesthetic significance.

Arts
Stone carvings, called Chaityas, seen in street corners and courtyards
Kathmandu valley is described as "an enormous treasure house of art and sculptures", which are made of wood, stone, metal, and terracotta, and found in profusion in temples, shrines, stupas, gompas, chaityasm and palaces. The art objects are also seen in street corners, lanes, private courtyards and in open ground. Most art is in the form of icons of gods and goddesses. Kathmandu valley has had this art treasure for a very long time, but received worldwide recognition only after the country opened to the outside world in 1950.[54]
The religious art of Nepal and Kathmandu in particular consists of an iconic symbolism of the Mother Goddesses such as: Bhavani, Durga, Gaja-Lakshmi, Hariti-Sitala, Mahsishamardini, Saptamatrika (seven mother goddesses), and Sri-Lakshmi (wealth-goddess). From the 3rd century BCE, apart from the Hindu gods and goddesses, Buddhist monuments from the Ashokan period (it is said that Ashoka visited Nepal in 250 BC) have embellished Nepal in general and the valley in particular. These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.[68]
A broad typology has been ascribed to the decorative designs and carvings created by the people of Nepal. These artists have maintained a blend of Hinduism and Buddhism. The typology, based on the type of material used are: stone art, metal art, wood art, terracotta art, and painting.[69]
Museums
Kathmandu is home to a number of museums and art galleries, including the National Museum of Nepal and the Natural History Museum of Nepal. Nepal's art and architecture is an amalgamation of two ancient religions, Hinduism and Buddhism. These are amply reflected in the many temples, shrines, stupas, monasteries, and palaces in the seven well-defined Monument Zones of the Kathmandu valley are part of a UNESCO World Heritage Site. This amalgamation is also reflected in the planning and exhibitions in museums and art galleries throughout Kathmandu and its sister cities of Patan and Bhaktapur. The museums display unique artefacts and paintings from the 5th century CE to the present day, including archaeological exportation.[70]
Museums and art galleries in Kathmandu include:[70]
The National Museum
The Natural History Museum
Hanuman Dhoka Palace Complex
The Kaiser Library
The National Art Gallery
The NEF-ART (Nepal Fine Art) Gallery
The Nepal Art Council Gallery
Narayanhiti Palace Museum
The Taragaon Museum
National Museum of Nepal
The National Museum is in the western part of Kathmandu, near the Swayambhunath stupa in a historical building constructed in the early 19th century by General Bhimsen Thapa. It is the most important museum in the country, housing an extensive collection of weapons, art and antiquities of historic and cultural importance. The museum was established in 1928 as a collection house of war trophies and weapons, and the initial name of this museum was Chhauni Silkhana, meaning "the stone house of arms and ammunition". Given its focus, the museum contains many weapons, including locally made firearms used in wars, leather cannons from the 18th–19th century, and medieval and modern works in wood, bronze, stone and paintings.[71]
The Natural History Museum is in the southern foothills of Swayambhunath hill and has a sizeable collection of different species of animals, butterflies, and plants. The museum is noted for its display of species, from prehistoric shells to stuffed animals.[71]
The Tribhuvan Museum contains artifacts related to King Tribhuvan (1906–1955). It has a variety of pieces including his personal belongings, letters, and papers, memorabilia related to events he was involved in and a rare collection of photos and paintings of Royal family members. The Mahendra Museum is dedicated to the King Mahendra (1920–1972). Like the Tribhuvan Museum, it includes his personal belongings such as decorations, stamps, coins and personal notes and manuscripts, but it also has structural reconstructions of his cabinet room and office chamber. The Hanumandhoka Palace, a lavish medieval palace complex in the Durbar, contains three separate museums of historic importance. These museums include the Birendra museum, which contains items related to the second-last monarch, King Birendra.[71]
The enclosed compound of the Narayanhiti Palace Museum is in the north-central part of Kathmandu. "Narayanhiti" (Nepali: नारायणहिटी) comes from Narayana (Nepali: नारायण), a form of the Hindu god Lord Vishnu, and Hiti (Nepali: हिटी), meaning "water spout" (the temple of lord Vishnu is opposite to the palace, and the water spout is east of the main entrance to the precinct). The current palace building was built in 1970 in front of the old palace, built in 1915, in the form of a contemporary pagoda. It was built on the occasion of the marriage of the then crown prince and heir apparent to the throne, Birendra. The southern gate of the palace is at the crossing of Prithvipath and Durbar Marg roads. The palace area covers 30 hectares (74 acres) and is fully secured with gates on all sides.[72][73][74] This palace was the scene of the Nepali royal massacre. After the fall of the monarchy, it has been converted into a museum.
The Taragaon Museum presents the modern history of the Kathmandu valley.[75] It seeks to document 50 years of research and cultural heritage conservation of the Kathmandu Valley, documenting what artists, photographers, architects, and anthropologists from abroad had contributed in the second half of the 20th century. The actual structure of the museum showcases restoration and rehabilitation efforts to preserve the built heritage of Kathmandu. It was designed by Carl Pruscha (master-planner of the Kathmandu Valley)[76] in 1970 and constructed in 1971.[77] Restoration works began in 2010 to rehabilitate the Taragaon hostel into the Taragaon Museum. The design uses local brick along with modern architectural design elements, as well as the use of circle, triangles and squares.[76] The museum is within a short walk from the Boudhanath stupa, which itself can be seen from the museum tower.
Art galleries
A Buddhist statue display in Kathmandu
Kathmandu is a centre for art in Nepal, displaying the work of contemporary artists in the country and also collections of historical artists. Patan in particular is an ancient city noted for its fine arts and crafts. Art in Kathmandu is vibrant, demonstrating a fusion of traditionalism and modern art, derived from a great number of national, Asian, and global influences. Nepali art is commonly divided into two areas: the idealistic traditional painting known as Paubhas in Nepal and perhaps more commonly known as Thangkas in Tibet, closely linked to the country's religious history and on the other hand the contemporary western-style painting, including nature-based compositions or abstract artwork based on Tantric elements and social themes of which painters in Nepal are well noted for.[71] Internationally, the British-based charity, the Kathmandu Contemporary Art Centre is involved with promoting arts in Kathmandu.[78]
Kathmandu houses many notable art galleries. The NAFA Gallery, operated by the Arts and crafts Department of the Nepal Academy is housed in Sita Bhavan, a neo-classical old Rana palace.[71]
The Srijana Contemporary Art Gallery, inside the Bhrikutimandap Exhibition grounds, hosts the work of contemporary painters and sculptors, and regularly organizes exhibitions. It also runs morning and evening classes in the schools of art. Also of note is the Moti Azima Gallery, in a three-storied building in Bhimsenthan which contains an impressive collection of traditional utensils and handmade dolls and items typical of a medieval Newar house, giving an important insight into Nepali history. The J Art Gallery near the former royal palace in Durbarmarg displays the artwork of eminent, established Nepali painters. The Nepal Art Council Gallery, in the Babar Mahal, on the way to Tribhuvan International Airport contains artwork of both national and international artists and extensive halls regularly used for art exhibitions.[71]
Literature
The National Library of Nepal is located in Patan. It is the largest library in the country with more than 70,000 books in English, Nepali, Sanskrit, Hindi, and Nepal Bhasa. The library is in possession of rare scholarly books in Sanskrit and English dating from the 17th century AD. Kathmandu also contains the Kaiser Library, in the Kaiser Mahal on the ground floor of the Ministry of Education building. This collection of around 45,000 books is derived from a personal collection of Kaiser Shamsher Jang Bahadur Rana. It covers a wide range of subjects including history, law, art, religion, and philosophy, as well as a Sanskrit manual of Tantra, which is believed to be over 1,000 years old.[71] The 2015 earthquake caused severe damage to the Ministry of Education building, and the contents of the Kaiser Library have been temporarily relocated.
Asa Archives
The Asa Archives are also noteworthy. They specialize in medieval history and religious traditions of the Kathmandu valley. The archives, in Kulambhulu, have a collection of some 6,000 loose-leaf handwritten books and 1,000 palm-leaf manuscripts (mostly in Sanskrit or Nepal Bhasa) and a manuscript dated to 1464.[71]
Cinema and theatre
Kathmandu is home to Nepali cinema and theatres. The city contains several theatres, including the National Dance Theatre in Kanti Path, the Ganga Theatre, the Himalayan Theatre and the Aarohan Theater Group founded in 1982. The M. Art Theater is based in the city. The Gurukul School of Theatre organizes the Kathmandu International Theater Festival, attracting artists from all over the world.[79] A mini theatre has been opened at the Hanumandhoka Durbar Square, established by the Durbar Conservation and Promotion Committee.
Kathmandu has a number of cinemas (old single screen establishments and some new multiplexes) showing Nepali, Bollywood and Hollywood films. Some old establishments include Vishwajyoti Cinema Hall, Jai Nepal Hall, Kumari Cinema Hall, Gopi Krishna Cinema Hall and Guna Cinema Hall. Kathmandu also houses some international standard cinema theatres and multiplexes, such as QFX Cinemas, Cine De Chef, Fcube Cinemas, Q's Cinemas, Big Movies, BSR Movies and many more.
Music
Traditional Buddhist musical performance during Gunla
Kathmandu is the center of music and dance in Nepal, and these art forms are integral to understanding the city. Musical performances are organized in cultural venues. Music is a part of the traditional aspect of Kathmandu. Gunla is the traditional music festival according to Nepal Sambat. Newar music originated in Kathmandu. Furthermore, music from all over Nepal can be found in Kathmandu.
A number of hippies visited Kathmandu during the 1970s and introduced rock and roll, rock, and jazz to the city. Kathmandu is noted internationally for its jazz festival, popularly known as Jazzmandu. It is the only jazz festival in the Himalayan region and was established in March 2002. The festival attracts musicians from countries worldwide, such as Australia, Denmark, United States, Benin, and India.[80]
The city has been referenced in numerous songs, including works by Cat Stevens ('Katmandu', Mona Bone Jakon (1970)), Bob Seger ('Katmandu', Beautiful Loser (1975)), Rush ('A Passage to Bangkok', Pulling into Kathmandu; 2112, 1976), Krematorij ('Kathmandu', Three Springs (2000)), Fito Páez (Tráfico por Katmandú – "Traffic through Kathmandu") and Cavalcade ('Kathmandu Kid') 2019.
Cuisine
One of the typical Nepali meals Dal bhat in Kathmandu
The staple food of most people in Kathmandu is dal bhat. This consists of rice and lentil soup, generally served with vegetable curries, achar and sometimes Chutney. Momo, a type of Nepali version of Tibetan dumpling, has become prominent in Nepal with many street vendors and restaurants selling it. It is one of the most popular fast foods in Kathmandu. Various Nepali variants of momo including buff (i.e. buffalo) momo, chicken momo, and vegetarian momo are famous in Kathmandu.
Most of the cuisines found in Kathmandu are non-vegetarian. However, the practice of vegetarianism is not uncommon, and vegetarian cuisines can be found throughout the city. Consumption of beef is very uncommon and considered taboo in many places. Buff (meat of water buffalo) is very common. There is a strong tradition of buff consumption in Kathmandu, especially among Newars, which is not found in other parts of Nepal. Consumption of pork was considered taboo until a few decades ago. Due to the intermixing with Kirat cuisine from eastern Nepal, pork has found a place in Kathmandu dishes. A fringe population of devout Hindus and Muslims consider it taboo. The Muslims forbid eating buff as from Quran while Hindus eat all varieties except beef as they consider cow to be a goddess and symbol of purity. The chief lunch/snack for locals and visitors is mostly Momo or Chowmein.
Kathmandu had only one western-style restaurant in 1955.[81] A large number of restaurants in Kathmandu have since opened, catering Nepali cuisine, Tibetan cuisine, Chinese cuisine and Indian cuisine in particular. Many other restaurants have opened to accommodate locals, expatriates, and tourists. The growth of tourism in Kathmandu has led to culinary creativity and the development of hybrid foods to accommodate for tourists such as American chop suey, which is a sweet-and-sour sauce with crispy noodles with a fried egg commonly added on top and other westernized adaptations of traditional cuisine.[81] Continental cuisine can be found in selected places. International chain restaurants are rare, but some outlets of Pizza Hut and KFC have recently opened there. It also has several outlets of the international ice-cream chain Baskin-Robbins.[82]
Kathmandu has a larger proportion of tea drinkers than coffee drinkers. Tea is widely served but is extremely weak by western standards. It is richer and contains tea leaves boiled with milk, sugar, and spices. Alcohol is widely drunk, and there are numerous local variants of alcoholic beverages. Drinking and driving is illegal, and authorities have a zero-tolerance policy.[83] Ailaa and thwon (alcohol made from rice) are the alcoholic beverages of Kathmandu, found in all the local bhattis (alcohol serving eateries). Chhyaang, tongba (fermented millet or barley) and raksi are alcoholic beverages from other parts of Nepal which are found in Kathmandu. However, shops and bars in Kathmandu widely sell western and Nepali beers.

Festivals
Samyak, a Buddhist festival during which statues of Buddhas from the ancient monasteries are displayed together. Note the statue of Hanuman next to the Buddhas in the picture, a common example of religious harmony in Kathmandu.
Most of the fairs and festivals in Kathmandu originated in the Malla period or earlier. Traditionally, these festivals were celebrated by Newars. In recent years, these festivals have found wider participation from other Kathmanduites as well. As the capital of the Nepal, various national festivals are celebrated in Kathmandu. With mass migration to the city, the cultures of Khas from the west, Kirats from the east, Bon/Tibetan from the north, and Mithila from the south meet in the capital and mingle harmoniously. The festivities such as the Ghode (horse) Jatra, Indra Jatra, Dashain Durga Puja festivals, Shivratri and many more are observed by all Hindu and Buddhist communities of Kathmandu with devotional fervor and enthusiasm. Social regulation in the codes enacted incorporates Hindu traditions and ethics. These were followed by the Shah kings and previous kings, as devout Hindus and protectors of the Buddhist religion.

Cultural continuity has been maintained for centuries in the exclusive worship of goddesses and deities in Kathmandu and the rest of the country. These deities include the Ajima,[84] Taleju (or Tulja Bhavani or Taleju Bhawani)[85][86] and her other forms : Digu Taleju (or Degu Taleju)[87] and Kumari (the living goddess).[88] The artistic edifices have now become places of worship in the everyday life of the people, therefore a roster is maintained to observe annual festivals. There are 133 festivals held in the year.[89]
Some of the traditional festivals observed in Kathmandu, apart from those previously mentioned, are Bada Dashain, Tihar, Chhath, Maghe Sankranti, Nag Panchami, Janai Purnima, Pancha Dan, Teej/Rishi Panchami, Pahan Charhe, Jana Baha Dyah Jatra (White Machchhendranath Jatra), and Matatirtha Aunsi.[56]
Religions
Hinduism
Kathmandu valley as seen from Halchowk during Deepawali, 2013
Assumedly, together with the kingdom of Licchhavi (c. 400 to 750), Hinduism and the endogam social stratification of the caste was established in Kathmandu Valley. The Pashupatinath Temple, Changu Narayan Temple, and the Kasthamandap are of particular importance to Hindus. Other notable Hindu temples in Kathmandu and the surrounding valley include Bajrayogini Temple, Dakshinkali Temple, Guhyeshwari Temple, and the Shobha Bhagawati shrine.
The Bagmati river which flows through Kathmandu is considered a holy river both by Hindus and Buddhists, and many Hindu temples are on the banks of this river. The importance of the Bagmati also lies in the fact that Hindus are cremated on its banks, and Kirants are buried in the hills by its side. According to the Nepali Hindu tradition, the dead body must be dipped three times into the Bagmati before cremation. The chief mourner (usually the first son) who lights the funeral pyre must take a holy riverwater bath immediately after cremation. Many relatives who join the funeral procession also take bath in the Bagmati or sprinkle the holy water on their bodies at the end of cremation as the Bagmati is believed to purify people spiritually.
Buddhism
Buddhism was brought into Kathmandu with the arrival of Buddhist monks during the time of Buddha (c. 563 – 483 BCE[90]). They established a forest monastery in Sankhu. This monastery was renovated by Shakyas after they fled genocide from Virudhaka (r. 491–461 BCE).
During the Hindu Lichchavi era (c. 400 to 750), various monasteries and orders were created which successively led to the formation of Newar Buddhism, which is still practiced in the primary liturgical language of Hinduism, Sanskrit.
Legendary Princess Bhrikuti (7th-century) and artist Araniko (1245–1306 CE) from that tradition of Kathmandu valley played a significant role in spreading Buddhism in Tibet and China. There are over 108 traditional monasteries (Bahals and Baháʼís) in Kathmandu based on Newar Buddhism. Since the 1960s, the permanent Tibetan Buddhist population of Kathmandu has risen significantly so that there are now over fifty Tibetan Buddhist monasteries in the area. Also, with the modernization of Newar Buddhism, various Theravada Bihars have been established.
Islam
Jama Masjid, Ghantaghar
Muslims in Kathmandu pray to Allah on Friday (the day of Namaj) often going to the Jame Masjid in Ghantaghar, near Ratnapark.
Kirat Mundhum
Kirant Mundhum is one of the indigenous animistic practices of Nepal. It is practiced by the Kirat people. Some animistic aspects of Kirant beliefs, such as ancestor worship (worship of Ajima) are also found in Newars of Kirant origin. Ancient religious sites believed to be worshipped by ancient Kirats, such as Pashupatinath, Wanga Akash Bhairabh (Yalambar) and Ajima are now worshipped by people of all Dharmic religions in Kathmandu. Kirats who have migrated from other parts of Nepal to Kathmandu practice Mundhum in the city.[91]
Other religions
Sikhism is practiced primarily in Gurudwara at Kupundole. An earlier temple of Sikhism is also present in Kathmandu which is now defunct.
Jainism is practiced by a small community. A Jain temple is present in Gyaneshwar, where Jains practice their faith.
According to the records of the Spiritual Assembly of the Baháʼís of Nepal, there are approximately 300 followers of the Baháʼí Faith in Kathmandu valley. They have a national office in Shantinagar, Baneshwor. The Baháʼís also have classes for children at the National Centre and other localities in Kathmandu.
Islam is practiced in Kathmandu but Muslims are a minority, accounting for about 4.4% of the population of Nepal.[92]
It is said that in Kathmandu alone there are 170 Christian churches. Christian missionary hospitals, welfare organizations, and schools are also operating. Nepali citizens who served as soldiers in Indian and British armies, who had converted to Christianity while in service, on return to Nepal continue to practice their religion. They have contributed to the spread of Christianity and the building of churches in Nepal and in Kathmandu, in particular.[93][94]
Education
The oldest modern school in Nepal, the Durbar High School, and the oldest college, the Tri-Chandra College, are both in Kathmandu. The largest (according to number of students and colleges), the oldest and most distinguished university in Nepal the Tribhuvan University, located in Kirtipur. The second largest university, Kathmandu University (KU), is in Dhulikhel, Kavre on the outskirts of Kathmandu. It is the second oldest university in Nepal, established in November 1991.[95] Not surprisingly the best schools and colleges of Nepal are located in Kathmandu and its adjoining cities. Every year thousands of students from all over Nepal arrive at Kathmandu to get admission in the various schools and colleges. One of the key concerns of educationists and concerned citizens is the massive outflux of students from Nepal to outside Nepal for studies. Every year thousands of students apply for No Objection Certificates for studying abroad. Consultancy firms specializing in preparing students to go abroad can be found in all prominent locations. The reason for such an outflux range from perceived low quality of education, political instability, fewer opportunities in the job market, opportunities for earning while learning abroad and better job prospects with an international degree.
Healthcare
Healthcare in Kathmandu is the most developed in Nepal, and the city and surrounding valley is home to some of the best hospitals and clinics in the country. Bir Hospital is the oldest, established in July 1889 by Bir Shamsher Jang Bahadur Rana. Notable hospitals include Bir Hospital, Nepal Medical College and Teaching Hospital (Jorpati), Tribhuvan University Institute of Medicine (Teaching Hospital), Patan Hospital, Kathmandu Model Hospital, Scheer Memorial Hospital, Om Hospital, Norvic Hospital, Grande International Hospital, Nobel Hospital and many more.
The city is supported by specialist hospitals/clinics such as Shahid Shukraraj Tropical Hospital, Shahid Gangalal Foundation, Kathmandu Veterinary Hospital, Nepal Eye Hospital, Kanti Children's Hospital, Nepal International Clinic (Travel and Mountain Medicine Center), Neuro Center, Spinal Rehabilitation center and Bhaktapur Cancer Hospital. Most of the general hospitals are in the city center, although several clinics are elsewhere in Kathmandu district.
Tilganga Institute of Ophthalmology is an Ophthalmological hospital in Kathmandu. It pioneered the production of low cost intraocular lenses (IOLs), which are used in cataract surgery.[96] The team of Dr. Sanduk Ruit in Tilganga pioneered sutureless small-incision cataract surgery (SICS),[97][98] a technique which has been used to treat 4 million of the world's 20 million people with cataract blindness.
Medical colleges
Institute of Medicine, the central college of Tribhuvan University is the first medical college of Nepal and is in Maharajgunj, Kathmandu. It was established in 1972 and started to impart medical education from 1978. Other major institutions include Patan Academy of Health Sciences, Kathmandu Medical College, Nepal Medical College, KIST Medical College, Nepal Army Institute of Health Sciences, National Academy of Medical Sciences (NAMS) and Kathmandu University School of Medical Sciences (KUSMS), are also in or around Kathmandu.
Economy
The location and terrain of Kathmandu have played a significant role in the development of a stable economy which spans millennia. The city is in an ancient lake basin, with fertile soil and flat terrain. This geography helped form a society based on agriculture. This, combined with its location between India and China, helped establish Kathmandu as an important trading centre over the centuries. Kathmandu's trade is an ancient profession that flourished along an offshoot of the Silk Road which linked India and Tibet. From centuries past, Lhasa Newar merchants of Kathmandu have conducted trade across the Himalaya and contributed to spreading art styles and Buddhism across Central Asia.[100] Other traditional occupations are farming, metal casting, woodcarving, painting, weaving, and pottery.[101]
Kathmandu is the most important industrial and commercial centre in Nepal. The Nepal Stock Exchange, the head office of the national bank, the chamber of commerce, as well as head offices of national and international banks, telecommunication companies, the electricity authority, and various other national and international organizations are in Kathmandu. The major economic hubs are the New Road, Durbar Marg, Ason and Putalisadak.[101]
The economic output of the metropolitan area of around Rs. 550 billion approximately per year alone is worth more than one third of national GDP (nominal), while the per capita income of $2200 is approximately three times the national average.[102] Kathmandu exports handicrafts, artworks, garments, carpets, pashmina, paper; trade accounts for 21% of its revenues.[101][102] Manufacturing is also important and accounts for 19% of the revenue that Kathmandu generates. Garments and woolen carpets are the most notable manufactured products.[102] Other economic sectors in Kathmandu include agriculture (9%), education (6%), transport (6%), and hotels and restaurants (5%).[102] Kathmandu is famous for lokta paper and pashmina shawls.
Tourism
Tourism is considered another important industry in Nepal. This industry started around 1950, as the country's political makeup changed and ended the country's isolation from the rest of the world. In 1956, air transportation was established and the Tribhuvan Highway, between Kathmandu and Raxaul (at India's border), was started. Separate organizations were created in Kathmandu to promote this activity; some of these include the Tourism Development Board, the Department of Tourism and the Civil Aviation Department. Furthermore, Nepal became a member of several international tourist associations. Establishing diplomatic relations with other nations further accentuated this activity. The hotel industry, travel agencies, training of tourist guides, and targeted publicity campaigns are the chief reasons for the remarkable growth of this industry in Nepal, and in Kathmandu in particular.[103] Since then, tourism in Nepal has thrived. It is the country's most important industry.[104] Tourism is a major source of income for most of the people in the city, with several hundred thousand visitors annually. Hindu and Buddhist pilgrims from all over the world visit Kathmandu's religious sites such as Pashupatinath, Swayambhunath, Boudhanath, Changunarayan and Budhanilkantha. From a mere 6,179 tourists in 1961/62, the number increased to 491,504 in 1999/2000. In economic terms, the foreign exchange registered 3.8% of the GDP in 1995/96 but then started declining. Following the end of the Maoist insurgency, there was a significant rise in the number of tourist arrivals, with 509,956 tourists recorded in 2009. Since then, tourism has improved as the country transitioned into a republic. The high level of tourism is attributed to the natural grandeur of the Himalayas and the rich cultural heritage of the country.[103]
Hyatt Regency, Kathmandu
The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel that was coined to rhyme with Thamel.[105] Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveller's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Ason is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.
With the opening of the tourist industry after the change in the political scenario of Nepal in 1950, the hotel industry drastically improved.[106] Now Kathmandu boasts several luxuries such as the Hyatt Regency, Dwarika's, Hotel Yak & Yeti, The Everest Hotel, Hotel Radisson, Hotel De L'Annapurna, The Malla Hotel, Shangri-La Hotel (not operated by the Shangri-La Hotel Group) and Hotel Shanker. There are several four-star hotels such as Akama Hotel, Hotel Vaishali, Hotel Narayani, The Blue Star and Grand Hotel. The Garden Hotel, Hotel Ambassador, and Aloha Inn are among the three-star hotels in Kathmandu. Hotels like Hyatt Regency, De L'Annapurna, and Yak & Yeti are among the five-star hotels with casinos as well.
Transport
The total length of roads in Nepal is recorded to be 17,182 km (10,676 mi), as of 2003–04. This fairly large network has helped the economic development of the country, particularly in the fields of agriculture, horticulture, vegetable farming, industry and also tourism.[108] In view of the hilly terrain, transportation takes place in Kathmandu are mainly by road and air. Kathmandu is connected by the Tribhuvan Highway to the south connecting India, Prithvi Highway to the west and Araniko Highway to the north connecting China. The BP Highway connects Kathmandu to the eastern part of Nepal through Sindhuli.[109] The fast-track is under construction which will be the shortest route to connect Terai with the valley.
Sajha Yatayat provides regular bus services throughout Kathmandu and the surrounding valley. Other bus companies including micro-bus companies operate several unscheduled routes. Trolleybusses used to operate on the route between Tripureshwor and Suryabinayak on a 13-kilometer route.
Air
The main international airport serving Kathmandu valley is the Tribhuvan International Airport, about 6 kilometres (3.7 mi) from the city centre and is operated by the Civil Aviation Authority of Nepal.[111] It has two terminals, one domestic and one international. At present, it connects 30 cities around the globe in Europe, Asia and the Middle East such as Istanbul, Delhi, Mumbai, Bangalore, Kolkata, Singapore, Bangkok, Kuala Lumpur, Dhaka, Paro, Lhasa, Chengdu, Guangzhou and Hong Kong.[111] Since 2013, Turkish Airlines connects Istanbul to Kathmandu.[112] Oman Air also connects Muscat to Kathmandu since 2010.[113] Nepal Airlines started flying to Tokyo-Narita from March 2, 2020. Regionally, several Nepali airlines operate from the city, inc
8th magnitude comet in Camelopardalis. I took 20 exposures of 2 minutes at ISO 1600 with a 480/80mm f/6 scope.
The scope was aligned on the stars but in post-processing with PixInsight, this image is aligned on the comet with NO attempt to remove or blur out background stars. It shows the movement and colour of the background stars well,

Comet Leonard increased in brightness by more than 2 magnitudes and within a day faded and then faded further in the next day.
COBS (Comet OBSveration database) contributions indicates that C/2021 Leonard had a significant outburst just prior to its recovery in the evening sky on December 15/16 2021. The comet flared to mag 3.5 and then quickly subsided to mag 5 by December 18. These three images were captured with a Vixen VSD 100 mm telescope and a Nikon Z7II camera mounted on a Vixen SXP. About 2.5 minutes of images were acquired with subs and stacked with AstroPixelProcessor and finished with Photoshop. With clouds and haze in Tucson and Comet Leonard gaining altitude each day the differences shown are not normalized and are a qualitative product of the captures. On December 17 there was considerable haze that like reddened the coma shown.
The photos were converted to BW, stretched, and then a inverted to show the coma stretched greatly to show the faint coma. The outburst on Dec 15/16 ejected much coma material. This then appears to be observed as an extended coma trail 24 h later in the middle image on December 17, and without the continuing outburst on December 18th the coma is much smaller and compact in the faded comet.
An admittedly popular subject and the only "twist" here is that I captured this image from a light-polluted, near-city-center location -- a place where I attempt very little deep-sky photography. To try and work around the light pollution I used an extreme number of short exposures combined with a light-pollution filter (and the filter itself resulted in about a two-thirds stop loss in effective broadband exposure). Note that even with this short exposure I was beginning to see a little bit of sky fog in my images given the bright sky and my relatively "fast" telescope and camera.
Near to the very top center edge of this image is the distant spiral galaxy UGC 2838 (see image notes). It appears as a very tiny, flying-saucer-shaped disk with a reported magnitude of around 16 (perhaps 60,000 times fainter than the star Electra, the bright member of the Pleiades cluster that is nearest to the top center of this photo). Of course, this star appears brighter only because it is much, much closer to us than is the galaxy (the distance to the star may be "only" 400 light years, while the galaxy may be over 300 million light years away).

Kathmandu (/ˌkætmænˈduː/;[2] Nepali: काठमाडौँ, Nepali pronunciation: [ˈkaʈʰmaɳɖu]) is the capital and largest city of Nepal, with a population of around 1 million. Also known as the city of temples, the city stands at an elevation of approximately 1,400 metres (4,600 feet) above sea level in the bowl-shaped Kathmandu valley in central Nepal. The valley was historically called the "Nepal Mandala" and has been the home of the Newar people, a cosmopolitan urban civilization in the Himalayan foothills. The city was the royal capital of the Kingdom of Nepal and hosts palaces, mansions and gardens of the Nepalese aristocracy. It has been home to the headquarters of the South Asian Association for Regional Cooperation (SAARC) since 1985. Today, it is the seat of government of the Nepalese republic, established in 2008, and is part of the Bagmati Province.
Kathmandu is and has been for many years the centre of Nepal's history, art, culture, and economy. It has a multi-ethnic population within a Hindu and Buddhist majority. Religious and cultural festivities form a major part of the lives of people residing in Kathmandu. Tourism is an important part of the economy in the city. In 2013, Kathmandu was ranked third among the top ten upcoming travel destinations in the world by TripAdvisor, and ranked first in Asia. The city is considered the gateway to the Nepalese Himalayas and is home to several world heritage sites: the Durbar Square, Swayambhunath, Boudhanath and Pashupatinath. Kathmandu valley is growing at 4 percentange per year according to the World Bank in 2010, making it one of the fastest-growing metropolitan areas in South Asia, and the first region in Nepal to face the unprecedented challenges of rapid urbanization and modernization at a metropolitan scale.
Historic areas of Kathmandu were severely damaged by a 7.8 magnitude earthquake in April 2015. Some of the buildings have been restored while some remain in the process of reconstruction.
Etymology
The indigenous Newari term for Kathmandu valley is Yen. The Nepali name Kathmandu comes from Kasthamandap, which stood in the Durbar Square. In Sanskrit, Kāṣṭha (Sanskrit: काष्ठ) means "Wood" and Maṇḍapa (Sanskrit: मण्डप) means "Pavilion". This public pavilion, also known as Maru Satta in Newari, was rebuilt in 1596 by Biseth in the period of King Laxmi Narsingh Malla. The three-storey structure was made entirely of wood and used no iron nails nor supports. According to legends, all the timber used to build the pagoda was obtained from a single tree.[4] The structure collapsed during a major earthquake in April 2015.
The colophons of ancient manuscripts, dated as late as the 20th century, refer to Kathmandu as Kāṣṭhamaṇḍap Mahānagar in Nepal Mandala. Mahānagar means "great city". The city is called Kāṣṭhamaṇḍap in a vow that Buddhist priests still recite to this day. Thus, Kathmandu is also known as Kāṣṭhamaṇḍap. During medieval times, the city was sometimes called Kāntipur (Sanskrit: कान्तिपुर). This name is derived from two Sanskrit words – Kānti and Pur. Kānti is a word that stands for "beauty" and is mostly associated with light and Pur means place, thus giving it the meaning, "City of light".
Among the indigenous Newar people, Kathmandu is known as Yeṃ Deśa (Nepal Bhasa: येँ देश), and Patan and Bhaktapur are known as Yala Deśa (Nepal Bhasa: यल देश) and Khwopa Deśa (Nepal Bhasa: ख्वप देश) respectively.[5] "Yen" is the shorter form of Yambu (Nepal Bhasa: यम्बु), which originally referred to the northern half of Kathmandu. The older northern settlements were referred to as Yambi while the southern settlement was known as Yangala.[6][7]
The spelling "Katmandu" was often used in older English-language text. More recently, however, the spelling "Kathmandu" has become more common in English.
History
Archaeological excavations in parts of Kathmandu have found evidence of ancient civilizations. The oldest of these findings is a statue, found in Maligaon, that was dated at 185 AD.[9] The excavation of Dhando Chaitya uncovered a brick with an inscription in Brahmi script. Archaeologists believe it is two thousand years old.[9] Stone inscriptions are a ubiquitous element at heritage sites and are key sources for the history of Nepal.
The earliest Western reference to Kathmandu appears in an account of Jesuit Fathers the Portuguese Jesuit, Fr. Joao Cabral who passed through the Kathmandu Valley in the spring of 1628 [10]and was received graciously by the king of that time, probably King Lakshminarasimha Malla of Kathmandu on their way from Tibet to India,[11] and reported that they reached "Cadmendu", the capital of Nepal kingdom.[12]
Ancient history
The ancient history of Kathmandu is described in its traditional myths and legends. According to Swayambhu Purana, present-day Kathmandu was once a huge and deep lake named "Nagdaha", as it was full of snakes. The lake was cut drained by Bodhisatwa Manjushree with his sword, and the water was evacuated out from there. He then established a city called Manjupattan, and made Dharmakar the ruler of the valley land. After some time, a demon named Banasur closed the outlet, and the valley again turned into a lake. Then Lord Krishna came to Nepal, killed Banasur, and again drained out the water. He brought some Gopals along with him and made Bhuktaman the king of Nepal.[13][14][15]
Kotirudra Samhita of Shiva Purana, Chapter 11, Shloka 18 refers to the place as Nayapala city, which was famous for its Pashupati Shivalinga. The name Nepal probably originates from this city Nayapala.
Very few historical records exists of the period before medieval Licchavi rulers. According to Gopalraj Vansawali, a genealogy of Nepali monarchy, the rulers of Kathmandu Valley before the Licchavis were Gopalas, Mahispalas, Aabhirs, Kiratas, and Somavanshi.[15][16] The Kirata dynasty was established by Yalamber. During the Kirata era, a settlement called Yambu existed in the northern half of old Kathmandu. In some of the Sino-Tibetan languages, Kathmandu is still called Yambu. Another smaller settlement called Yengal was present in the southern half of old Kathmandu, near Manjupattan. During the reign of the seventh Kirata ruler, Jitedasti, Buddhist monks entered Kathmandu valley and established a forest monastery at Sankhu.

Licchavi era
The Licchavis from the Indo-Gangetic plain migrated north and defeated the Kiratas, establishing the Licchavi dynasty, circa 400 AD. During this era, following the genocide of Shakyas in Lumbini by Virudhaka, the survivors migrated north and entered the forest monastery lora masquerading as Koliyas. From Sankhu, they migrated to Yambu and Yengal (Lanjagwal and Manjupattan) and established the first permanent Buddhist monasteries of Kathmandu. This created the basis of Newar Buddhism, which is the only surviving Sanskrit-based Buddhist tradition in the world.[17] With their migration, Yambu was called Koligram and Yengal was called Dakshin Koligram[18] during most of the Licchavi era.[19]
Eventually, the Licchavi ruler Gunakamadeva merged Koligram and Dakshin Koligram, founding the city of Kathmandu.[19] The city was designed in the shape of Chandrahrasa, the sword of Manjushri. The city was surrounded by eight barracks guarded by Ajimas. One of these barracks is still in use at Bhadrakali (in front of Singha Durbar). The city served as an important transit point in the trade between India and Tibet, leading to tremendous growth in architecture. Descriptions of buildings such as Managriha, Kailaskut Bhawan, and Bhadradiwas Bhawan have been found in the surviving journals of travellers and monks who lived during this era. For example, the famous 7th-century Chinese traveller Xuanzang described Kailaskut Bhawan, the palace of the Licchavi king Amshuverma.[20] The trade route also led to cultural exchange as well. The artistry of the Newar people—the indigenous inhabitants of the Kathmandu Valley—became highly sought after during this era, both within the Valley and throughout the greater Himalayas. Newar artists travelled extensively throughout Asia, creating religious art for their neighbours. For example, Araniko led a group of his compatriot artists through Tibet and China. Bhrikuti, the princess of Nepal who married Tibetan monarch Songtsän Gampo, was instrumental in introducing Buddhism to Tibet.

Malla era
The Licchavi era was followed by the Malla era. Rulers from Tirhut, upon being attacked by Muslims, fled north to the Kathmandu valley. They intermarried with Nepali royalty, and this led to the Malla era. The early years of the Malla era were turbulent, with raids and attacks from Khas and Turk Muslims. There was also a devastating earthquake which claimed the lives of a third of Kathmandu's population, including the king Abhaya Malla. These disasters led to the destruction of most of the architecture of the Licchavi era (such as Mangriha and Kailashkut Bhawan), and the loss of literature collected in various monasteries within the city. Despite the initial hardships, Kathmandu rose to prominence again and, during most of the Malla era, dominated the trade between India and Tibet. Nepali currency became the standard currency in trans-Himalayan trade.
During the later part of the Malla era, Kathmandu Valley comprised four fortified cities: Kantipur, Lalitpur, Bhaktapur, and Kirtipur. These served as the capitals of the Malla confederation of Nepal. These states competed with each other in the arts, architecture, esthetics, and trade, resulting in tremendous development. The kings of this period directly influenced or involved themselves in the construction of public buildings, squares, and temples, as well as the development of waterspouts, the institutionalisation of trusts (called guthis), the codification of laws, the writing of dramas, and the performance of plays in city squares. Evidence of an influx of ideas from India, Tibet, China, Persia, and Europe among other places can be found in a stone inscription from the time of king Pratap Malla. Books have been found from this era that describe their tantric tradition (e.g. Tantrakhyan), medicine (e.g. Haramekhala), religion (e.g. Mooldevshashidev), law, morals, and history. Amarkosh, a Sanskrit-Nepal Bhasa dictionary from 1381 AD, was also found. Architecturally notable buildings from this era include Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, the former durbar of Kirtipur, Nyatapola, Kumbheshwar, the Krishna temple, and others.
Medieval era
The Gorkha Kingdom ended the Malla confederation after the Battle of Kathmandu in 1768. This marked the beginning of the modern era in Kathmandu. The Battle of Kirtipur was the start of the Gorkha conquest of the Kathmandu Valley. Kathmandu was adopted as the capital of the Gorkha empire, and the empire itself was dubbed Nepal. During the early part of this era, Kathmandu maintained its distinctive culture. Buildings with characteristic Nepali architecture, such as the nine-story tower of Basantapur, were built during this era. However, trade declined because of continual war with neighbouring nations. Bhimsen Thapa supported France against Great Britain; this led to the development of modern military structures, such as modern barracks in Kathmandu. The nine-storey tower Dharahara was originally built during this era.
Rana rule
Rana rule over Nepal started with the Kot Massacre of 1846, which occurred near Hanuman Dhoka Durbar. During this massacre, most of Nepal's high-ranking officials were massacred by Jung Bahadur Rana and his supporters. Another massacre, the Bhandarkhal Massacre, was also conducted by Kunwar and his supporters in Kathmandu. During the Rana regime, Kathmandu's alliance shifted from anti-British to pro-British; this led to the construction of the first buildings in the style of Western European architecture. The most well-known of these buildings include Singha Durbar, Garden of Dreams, Shital Niwas, and the old Narayanhiti palace. The first modern commercial road in the Kathmandu Valley, the New Road, was also built during this era. Trichandra College (the first college of Nepal), Durbar High School (the first modern school of Nepal), and Bir Hospital (the first hospital of Nepal) were built in Kathmandu during this era. Education was only accessible to the privileged class. Rana rule was marked by despotism, economic exploitation and religious persecution.
Geography
Kathmandu is in the northwestern part of the Kathmandu Valley to the north of the Bagmati river and covers an area of 50.7 km2 (19.6 sq mi). The average elevation is 1,400 metres (4,600 ft) above sea level.[23] The city is bounded by several other municipalities of the Kathmandu valley: south of the Bagmati by Lalitpur Metropolitan City (Patan), with which it forms one urban area surrounded by a ring road, to the southwest by Kirtipur and to the east by Madyapur Thimi. To the north the urban area extends into several municipalities; Nagarjun, Tarakeshwor, Tokha, Budhanilkantha, Gokarneshwor and Kageshwori Manohara. However, the urban agglomeration extends well beyond the neighbouring municipalities, e.g. to Bhaktapur, and nearly covers the entire Kathmandu valley.
Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumante Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,500–3,000 metres (4,900–9,800 ft), and have passes which provide access to and from Kathmandu and its valley.[24][25][26] An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.
The city of Kathmandu and the surrounding valley are in the Deciduous Monsoon Forest Zone (altitude range of 1,200–2,100 metres (3,900–6,900 ft)), one of five vegetation zones defined for Nepal. The dominant tree species in this zone are oak, elm, beech, maple and others, with coniferous trees at higher altitude.[27]

Kathmandu administration
Kathmandu and adjacent cities are composed of neighbourhoods, which are utilized quite extensively and more familiar among locals. However, administratively the city is divided into 32 wards, numbered from 1 to 32. Earlier, there were 35 wards which made it the metropolitan city with the largest number of the wards.[28]
Kathmandu agglomeration
There is no officially defined agglomeration of Kathmandu. The urban area of the Kathmandu valley is split among three different districts (second level of administrative divisions within a province), which extend very little beyond the valley fringe, except towards the southern ranges, which have a comparatively small population.[29] They have the three highest population densities in the country. These 3 districts are administered by 21 local level bodies; 2 metropolitan cities (Kathmandu and Lalitpur), 16 municipalities and 3 rural municipalities. Imperial conversion
Five major climatic regions are found in Nepal. Of these, Kathmandu Valley is in the Warm Temperate Zone (elevation ranging from 1,200 to 2,300 metres (3,900 to 7,500 ft)), where the climate is fairly temperate, atypical for the region. This zone is followed by the Cool Temperate Zone with elevation varying between 2,100 and 3,300 metres (6,900 and 10,800 ft). Under Köppen's climate classification, portions of the city with lower elevations have a humid subtropical climate (Cwa), while portions of the city with higher elevations generally have a subtropical highland climate (Cwb). In the Kathmandu Valley, which is representative of its valley's climate, the average summer temperature varies from 28 to 30 °C (82 to 86 °F). The average winter temperature is 10.1 °C (50.2 °F).
The city generally has a climate with warm days followed by cool nights and mornings. Unpredictable weather is expected, given that temperatures can drop to 1 °C (34 °F) or less during the winter. During a 2013 cold front, the winter temperatures of Kathmandu dropped to −4 °C (25 °F), and the lowest temperature was recorded on 10 January 2013, at −9.2 °C (15.4 °F). Rainfall is mostly monsoon-based (about 65% of the total concentrated during the monsoon months of June to September), and decreases substantially (100 to 200 cm (39 to 79 in)) from eastern Nepal to western Nepal. Rainfall has been recorded at about 1,400 millimetres (55.1 in) for the Kathmandu valley, and averages 1,407 millimetres (55.4 in) for the city of Kathmandu. On average humidity is 75%.[24][30][31] The chart below is based on data from the Nepal Bureau of Standards & Meteorology, Weather Meteorology for 2005. The chart provides minimum and maximum temperatures during each month. The annual amount of precipitation was 1,124 millimetres (44.3 in) for 2005, as per monthly data included in the table above.[31] The decade of 2000–2010 saw highly variable and unprecedented precipitation anomalies in Kathmandu. This was mostly due to the annual variation of the southwest monsoon.[citation needed] For example, 2001 recorded only 356 mm (14 in) of precipitation due to an extraordinarily weak monsoon season. In contrast, 2003 was the wettest year ever in Kathmandu, totaling over 2,900 mm (114 in) of precipitation due to an exceptionally strong monsoon season.
Air quality
Air pollution is a major issue in the Kathmandu Valley.[36][37][38] According to the 2016 World Health Organization's Ambient Air Pollution Database,[39] the annual average PM2.5 (particulate matter) concentration in 2013 was 49 μg/m3, which is 4.9 times higher than recommended by the World Health Organization.[40][41] Starting in early 2017, the Government of Nepal and the Embassy of the United States in Kathmandu have monitored and publicly share real-time air quality data. In Nepal and Kathmandu, the annual premature deaths due to air pollution reached 37,399 and 9,943 respectively, according to a Republica news report published on 23 November, 2019. This indicates, around a quarter of the total deaths due to air pollution in Nepal are in Kathmandu.
Government and public services
Kathmandu Municipal Corporation (KMC) is the chief nodal agency for the administration of Kathmandu. The Municipality of Kathmandu was upgraded to a metropolitan city in 1995.
Metropolitan Kathmandu is divided into five sectors: the Central Sector, the East Sector, the North Sector, the City Core and the West Sector. For civic administration, the city is further divided into 35 administrative wards. The Council administers the Metropolitan area of Kathmandu city through its 177 elected representatives and 20 nominated members. It holds biannual meetings to review, process and approve the annual budget and make major policy decisions.[24][44] The ward's profile documents for the 35 wards prepared by the Kathmandu Metropolitan Council is detailed and provides information for each ward on population, the structure and condition of houses, the type of roads, educational, health and financial institutions, entertainment facilities, parking space, security provisions, etc. It also includes lists of development projects completed, on-going and planned, along with informative data about the cultural heritage, festivals, historical sites and the local inhabitants. Ward 16 is the largest, with an area of 437.4 ha; ward 26 is the smallest, with an area of 4 ha.[45]
Kathmandu is the headquarters of the surrounding Kathmandu district. The city of Kathmandu forms this district along with 10 other municipalities, namely Budanilkantha, Chandragiri, Dakshinkali, Gokarneshwar, Kageshwari Manohara, Kirtipur, Nagarjun, Shankharapur, Tarakeshwar and Tokha.
Law and order
The Metropolitan Police is the main law enforcement agency in the city. It is headed by a commissioner of police. The Metropolitan Police is a division of the Nepal Police, and the administrative control lies with the Ministry of Home Affairs.

Fire service
The fire service, known as the Barun Yantra Karyalaya (Nepali: वारुण यन्त्र कार्यालय), opened its first station in Kathmandu in 1937 with a single-vehicle.[46] An iron tower was erected to monitor the city and watch for a fire. As a precautionary measure, firemen were sent to the areas which were designated as accident-prone areas.[46] In 1944, the fire service was extended to the neighbouring cities of Lalitpur and Bhaktapur. In 1966, a fire service was established in Kathmandu central airport.[46] In 1975, a West German government donation added seven fire engines to Kathmandu's fire service.[46] The fire service in the city is also overlooked by an international non-governmental organization, the Firefighters Volunteer Association of Nepal (FAN), which was established in 2000 with the purpose of raising public awareness about fire and improving safety.[46]
Electricity and water supply
Public baths, Kathmandu. 1979
Electricity in Kathmandu is regulated and distributed by the Nepal Electricity Authority (NEA). Water supply and sanitation facilities are provided by the Kathmandu Upatyaka Khanepani Limited (KUKL). There is a severe shortage of water for household purposes such as drinking, bathing, cooking and washing and irrigation. People have been using bottled mineral water, water from tank trucks and from the ancient dhunge dharas (Nepali: ढुङ्गे धारा) for all the purposes related to water. The city water shortage should be solved by the completion of the much plagued Melamchi Water Supply Project by the end of 2019.[47][48]
Waste management
Waste management may be through composting in municipal waste management units, and at houses with home composting units. Both systems are common and established in India and neighbouring countries.[49]
Demographics
Kathmandu's urban cosmopolitan character has made it the most populous city in Nepal, recording a population of 671,846 residents living in 235,387 households in the metropolitan area, according to the 2001 census.[50] According to the National Population Census of 2011, the total population of Kathmandu city was 975,543 with an annual growth rate of 6.12% with respect to the population figure of 2001. 70% of the total population residing in Kathmandu are aged between 15 and 59.
Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of 5,076.6 hectares (12,545 acres) has expanded to 8,214 hectares (20,300 acres) in 2001. With this new area, the population density which was 85 in 1991 remained 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.[51]
Currently based on various data Kathmandu population is 1,442,300 with population density of 29,166.835 per sq.km making it as 6th densely populated city in the world.
Ethnic groups
The largest ethnic groups residing in Kathmandu Metropolitan City consists of primarily various caste groups of the Newar community at 25%, Hill Janajati/Adivisis like Tamang, Kirat, Gurung, Magar, Sherpa, etc. making~20%, Khas Brahmin at 24%, Khas Chhetri at 20%, and 7% Terai groups including Madhesi castes and Terai Janajatis/Adivasis like Tharus.[52] More recently, other hill ethnic groups and caste groups from Terai have come to represent a substantial proportion of the city's population. The major languages are Nepali and Nepal Bhasa, while English is understood by many, particularly in the service industry. According to data from 2011, the major religions in Kathmandu city are Hinduism 81.3%, Buddhism 9%, Islam 4.4% and other 5.2%.[53]
The linguistic profile of Kathmandu underwent drastic changes during the Shah dynasty's rule because of its strong bias towards the Hindu culture. Sanskrit language therefore was preferred and people were encouraged to learn it even by attending Sanskrit learning centres in Terai. Sanskrit schools were specially set up in Kathmandu and in the Terai region to inculcate traditional Hindu culture and practices originated from Nepal.[54]
Architecture and cityscape
The ancient trade route between India and Tibet that passed through Kathmandu enabled a fusion of artistic and architectural traditions from other cultures to be amalgamated with local art and architecture.[56] The monuments of Kathmandu City have been influenced over the centuries by Hindu and Buddhist religious practices. The architectural treasure of the Kathmandu valley has been categorized under the well-known seven groups of heritage monuments and buildings. In 2006 UNESCO declared these seven groups of monuments as a World Heritage Site (WHS). The seven monuments zones cover an area of 189 hectares (470 acres), with the buffer zone extending to 2,394 hectares (5,920 acres). The Seven Monument Zones inscribed originally in 1979 and with a minor modification in 2006 are the Durbar squares of Hanuman Dhoka, Patan and Bhaktapur, the Hindu temples of Pashupatinath and Changunarayan, the Buddhist stupas of Swayambhunath and Boudhanath.[57][58]
Durbar Squares
Main articles: Kathmandu Durbar Square and Hanuman Dhoka
The literal meaning of Durbar Square is a "place of palaces." There are three preserved Durbar Squares in Kathmandu valley and one unpreserved in Kirtipur. The Durbar Square of Kathmandu is in the old city and has heritage buildings representing four kingdoms (Kantipur, Lalitpur, Bhaktapur, Kirtipur); the earliest being the Licchavi dynasty. The complex has 50 temples and is distributed in two quadrangles of the Durbar Square. The outer quadrangle has the Kasthamandap, Kumari Ghar, and Shiva-Parvati Temple; the inner quadrangle has the Hanuman Dhoka palace. The squares were severely damaged in the April 2015 earthquake.
Hanuman Dhoka is a complex of structures with the royal palace of the Malla kings and of the Shah dynasty. It is spread over five acres. The eastern wing, with ten courtyards, is the oldest part, dating to the mid-16th century. It was expanded by King Pratap Malla in the 17th century with many temples. The royal family lived in this palace until 1886 when they moved to Narayanhiti Palace. The stone inscription outside is in fifteen languages.
Kumari Ghar is a palace in the centre of the Kathmandu city, next to the Durbar square where a royal Kumari selected from several Kumaris resides. Kumari, or Kumari Devi, is the tradition of worshipping young pre-pubescent girls as manifestations of the divine female energy or devi in South Asian countries. In Nepal the selection process is very rigorous. Previously, during the time of the monarchy, the queen and the priests used to appoint the proposed Kumari with delicate process of astrological examination and physical examination of 32 'gunas'. The china (Nepali: चिना), an ancient Hindu astrological report, of the Kumari and the reigning king, was ought to be similar. The Kumari is believed to be a bodily incarnation of the goddess Taleju (the Nepali name for Durga) until she menstruates, after which it is believed that the goddess vacates her body. Serious illness or a major loss of blood from an injury also causes her to revert to common status. The current Kumari, Trishna Shakya, age three at the time of appointment, was installed in September 2017 succeeding Matina Shakya who was the first Kumari of Kathmandu after the end of the monarchy.[59]
Kasthamandap is a three-storeyed temple enshrining an image of Gorakhnath. It was built in the 16th century in pagoda style. The name of Kathmandu is a derivative of the word Kasthamandap. It was built under the reign of King Laxmi Narsingha Malla. Kasthamandap stands at the intersection of two ancient trade routes linking India and Tibet at Maru square. It was originally built as a rest house for travellers.

The Pashupatinath Temple (Nepali: पशुपतिनाथ मन्दिर) is a famous 5th century Hindu temple dedicated to Lord Shiva. Located on the banks of the Bagmati river, the Pashupatinath Temple is the oldest Hindu temple in Kathmandu.[60] It served as the seat of national deity, Lord Pashupatinath, until Nepal was secularized. However, a significant part of the temple was destroyed by Mughal invaders in the 14th century and little or nothing remains of the original 5th-century temple exterior. The temple as it stands today was built in the 19th century, although the image of the bull and the black four-headed image of Pashupati are at least 300 years old.[61] The temple is a UNESCO World Heritage Site.[61][62] Shivaratri, or the night of Lord Shiva, is the most important festival that takes place here, attracting thousands of devotees and sadhus.[citation needed]
Believers in Pashupatinath (mainly Hindus) are allowed to enter the temple premises, but non-Hindu visitors are allowed to view the temple only from the across the Bagmati River.[61] The priests who perform the services at this temple have been Brahmins from Karnataka in southern India since the time of Malla king Yaksha Malla.[63] This tradition is believed to have been started at the request of Adi Shankaracharya who sought to unify the states of Bharatam, a region in south Asia believed to be ruled by a mythological king Bharat, by encouraging cultural exchange. This procedure is followed in other temples around India, which were sanctified by Adi Shankaracharya.
The temple is built in the pagoda style of architecture, with cubic constructions and carved wooden rafters (tundal) on which they rest, and two-level roofs made of copper and gold.
Boudhanath
Boudhanath (Nepali: बौद्ध स्तुप; also written as Bouddhanath, Bodhnath, Baudhanath or the Khāsa Chaitya), is one of the holiest Buddhist sites in Nepal, along with the Swayambhunath. It is a very popular tourist site. Boudhanath is known as Khāsti by Newars and as Bauddha or Bodhnāth by speakers of Nepali.[64] About 11 km (7 mi) from the centre and northeastern outskirts of Kathmandu, the stupa's massive mandala makes it one of the largest spherical stupas in Nepal.[65] Boudhanath became a UNESCO World Heritage Site in 1979.
The base of the stupa has 108 small depictions of the Dhyani Buddha Amitabha. It is surrounded with a brick wall with 147 niches, each with four or five prayer wheels engraved with the mantra, om mani padme hum.[66] At the northern entrance where visitors must pass is a shrine dedicated to Ajima, the goddess of smallpox.[66] Every year the stupa attracts many Tibetan Buddhist pilgrims who perform full body prostrations in the inner lower enclosure, walk around the stupa with prayer wheels, chant, and pray.[66] Thousands of prayer flags are hoisted up from the top of the stupa downwards and dot the perimeter of the complex. The influx of many Tibetan refugees from China has seen the construction of over 50 Tibetan gompas (monasteries) around Boudhanath.
Swayambhu
Main article: Swayambhunath
Swayambhunath (Nepali: स्वयम्भू स्तूप) is a Buddhist stupa atop a hillock at the northwestern part of the city. This is among the oldest religious sites in Nepal. Although the site is considered Buddhist, it is revered by both Buddhists and Hindus. The stupa consists of a dome at the base; above the dome, there is a cubic structure with the eyes of Buddha looking in all four directions.[clarification needed] There are pentagonal toran above each of the four sides, with statues engraved on them. Behind and above the torana there are thirteen tiers. Above all the tiers, there is a small space above which lies a gajur.
Rani Pokhari

Ranipokhari (Nepali: रानी पोखरी, lit. 'Queen's Pond') is a historic artificial pond nestled in the heart of Kathmandu. It was built by king Pratap Malla in 1670 AD for his beloved queen after she lost her son and could not recover from her loss.[67] A large stone statue of an elephant in the south signifies the image of Pratap Malla and his two sons. Balgopaleshwor Temple stands still inside the temple above the pond. Rani Pokhari is opened once a year during the final day of Tihar i.e. Bhai Tika and Chhath festival. The world's largest Chhath takes place every year in Ranipokhari. The pond is one of Kathmandu's most famous landmarks and is known for its religious and aesthetic significance.

Arts
Stone carvings, called Chaityas, seen in street corners and courtyards
Kathmandu valley is described as "an enormous treasure house of art and sculptures", which are made of wood, stone, metal, and terracotta, and found in profusion in temples, shrines, stupas, gompas, chaityasm and palaces. The art objects are also seen in street corners, lanes, private courtyards and in open ground. Most art is in the form of icons of gods and goddesses. Kathmandu valley has had this art treasure for a very long time, but received worldwide recognition only after the country opened to the outside world in 1950.[54]
The religious art of Nepal and Kathmandu in particular consists of an iconic symbolism of the Mother Goddesses such as: Bhavani, Durga, Gaja-Lakshmi, Hariti-Sitala, Mahsishamardini, Saptamatrika (seven mother goddesses), and Sri-Lakshmi (wealth-goddess). From the 3rd century BCE, apart from the Hindu gods and goddesses, Buddhist monuments from the Ashokan period (it is said that Ashoka visited Nepal in 250 BC) have embellished Nepal in general and the valley in particular. These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.[68]
A broad typology has been ascribed to the decorative designs and carvings created by the people of Nepal. These artists have maintained a blend of Hinduism and Buddhism. The typology, based on the type of material used are: stone art, metal art, wood art, terracotta art, and painting.[69]
Museums
Kathmandu is home to a number of museums and art galleries, including the National Museum of Nepal and the Natural History Museum of Nepal. Nepal's art and architecture is an amalgamation of two ancient religions, Hinduism and Buddhism. These are amply reflected in the many temples, shrines, stupas, monasteries, and palaces in the seven well-defined Monument Zones of the Kathmandu valley are part of a UNESCO World Heritage Site. This amalgamation is also reflected in the planning and exhibitions in museums and art galleries throughout Kathmandu and its sister cities of Patan and Bhaktapur. The museums display unique artefacts and paintings from the 5th century CE to the present day, including archaeological exportation.[70]
Museums and art galleries in Kathmandu include:[70]
The National Museum
The Natural History Museum
Hanuman Dhoka Palace Complex
The Kaiser Library
The National Art Gallery
The NEF-ART (Nepal Fine Art) Gallery
The Nepal Art Council Gallery
Narayanhiti Palace Museum
The Taragaon Museum
National Museum of Nepal
The National Museum is in the western part of Kathmandu, near the Swayambhunath stupa in a historical building constructed in the early 19th century by General Bhimsen Thapa. It is the most important museum in the country, housing an extensive collection of weapons, art and antiquities of historic and cultural importance. The museum was established in 1928 as a collection house of war trophies and weapons, and the initial name of this museum was Chhauni Silkhana, meaning "the stone house of arms and ammunition". Given its focus, the museum contains many weapons, including locally made firearms used in wars, leather cannons from the 18th–19th century, and medieval and modern works in wood, bronze, stone and paintings.[71]
The Natural History Museum is in the southern foothills of Swayambhunath hill and has a sizeable collection of different species of animals, butterflies, and plants. The museum is noted for its display of species, from prehistoric shells to stuffed animals.[71]
The Tribhuvan Museum contains artifacts related to King Tribhuvan (1906–1955). It has a variety of pieces including his personal belongings, letters, and papers, memorabilia related to events he was involved in and a rare collection of photos and paintings of Royal family members. The Mahendra Museum is dedicated to the King Mahendra (1920–1972). Like the Tribhuvan Museum, it includes his personal belongings such as decorations, stamps, coins and personal notes and manuscripts, but it also has structural reconstructions of his cabinet room and office chamber. The Hanumandhoka Palace, a lavish medieval palace complex in the Durbar, contains three separate museums of historic importance. These museums include the Birendra museum, which contains items related to the second-last monarch, King Birendra.[71]
The enclosed compound of the Narayanhiti Palace Museum is in the north-central part of Kathmandu. "Narayanhiti" (Nepali: नारायणहिटी) comes from Narayana (Nepali: नारायण), a form of the Hindu god Lord Vishnu, and Hiti (Nepali: हिटी), meaning "water spout" (the temple of lord Vishnu is opposite to the palace, and the water spout is east of the main entrance to the precinct). The current palace building was built in 1970 in front of the old palace, built in 1915, in the form of a contemporary pagoda. It was built on the occasion of the marriage of the then crown prince and heir apparent to the throne, Birendra. The southern gate of the palace is at the crossing of Prithvipath and Durbar Marg roads. The palace area covers 30 hectares (74 acres) and is fully secured with gates on all sides.[72][73][74] This palace was the scene of the Nepali royal massacre. After the fall of the monarchy, it has been converted into a museum.
The Taragaon Museum presents the modern history of the Kathmandu valley.[75] It seeks to document 50 years of research and cultural heritage conservation of the Kathmandu Valley, documenting what artists, photographers, architects, and anthropologists from abroad had contributed in the second half of the 20th century. The actual structure of the museum showcases restoration and rehabilitation efforts to preserve the built heritage of Kathmandu. It was designed by Carl Pruscha (master-planner of the Kathmandu Valley)[76] in 1970 and constructed in 1971.[77] Restoration works began in 2010 to rehabilitate the Taragaon hostel into the Taragaon Museum. The design uses local brick along with modern architectural design elements, as well as the use of circle, triangles and squares.[76] The museum is within a short walk from the Boudhanath stupa, which itself can be seen from the museum tower.
Art galleries
A Buddhist statue display in Kathmandu
Kathmandu is a centre for art in Nepal, displaying the work of contemporary artists in the country and also collections of historical artists. Patan in particular is an ancient city noted for its fine arts and crafts. Art in Kathmandu is vibrant, demonstrating a fusion of traditionalism and modern art, derived from a great number of national, Asian, and global influences. Nepali art is commonly divided into two areas: the idealistic traditional painting known as Paubhas in Nepal and perhaps more commonly known as Thangkas in Tibet, closely linked to the country's religious history and on the other hand the contemporary western-style painting, including nature-based compositions or abstract artwork based on Tantric elements and social themes of which painters in Nepal are well noted for.[71] Internationally, the British-based charity, the Kathmandu Contemporary Art Centre is involved with promoting arts in Kathmandu.[78]
Kathmandu houses many notable art galleries. The NAFA Gallery, operated by the Arts and crafts Department of the Nepal Academy is housed in Sita Bhavan, a neo-classical old Rana palace.[71]
The Srijana Contemporary Art Gallery, inside the Bhrikutimandap Exhibition grounds, hosts the work of contemporary painters and sculptors, and regularly organizes exhibitions. It also runs morning and evening classes in the schools of art. Also of note is the Moti Azima Gallery, in a three-storied building in Bhimsenthan which contains an impressive collection of traditional utensils and handmade dolls and items typical of a medieval Newar house, giving an important insight into Nepali history. The J Art Gallery near the former royal palace in Durbarmarg displays the artwork of eminent, established Nepali painters. The Nepal Art Council Gallery, in the Babar Mahal, on the way to Tribhuvan International Airport contains artwork of both national and international artists and extensive halls regularly used for art exhibitions.[71]
Literature
The National Library of Nepal is located in Patan. It is the largest library in the country with more than 70,000 books in English, Nepali, Sanskrit, Hindi, and Nepal Bhasa. The library is in possession of rare scholarly books in Sanskrit and English dating from the 17th century AD. Kathmandu also contains the Kaiser Library, in the Kaiser Mahal on the ground floor of the Ministry of Education building. This collection of around 45,000 books is derived from a personal collection of Kaiser Shamsher Jang Bahadur Rana. It covers a wide range of subjects including history, law, art, religion, and philosophy, as well as a Sanskrit manual of Tantra, which is believed to be over 1,000 years old.[71] The 2015 earthquake caused severe damage to the Ministry of Education building, and the contents of the Kaiser Library have been temporarily relocated.
Asa Archives
The Asa Archives are also noteworthy. They specialize in medieval history and religious traditions of the Kathmandu valley. The archives, in Kulambhulu, have a collection of some 6,000 loose-leaf handwritten books and 1,000 palm-leaf manuscripts (mostly in Sanskrit or Nepal Bhasa) and a manuscript dated to 1464.[71]
Cinema and theatre
Kathmandu is home to Nepali cinema and theatres. The city contains several theatres, including the National Dance Theatre in Kanti Path, the Ganga Theatre, the Himalayan Theatre and the Aarohan Theater Group founded in 1982. The M. Art Theater is based in the city. The Gurukul School of Theatre organizes the Kathmandu International Theater Festival, attracting artists from all over the world.[79] A mini theatre has been opened at the Hanumandhoka Durbar Square, established by the Durbar Conservation and Promotion Committee.
Kathmandu has a number of cinemas (old single screen establishments and some new multiplexes) showing Nepali, Bollywood and Hollywood films. Some old establishments include Vishwajyoti Cinema Hall, Jai Nepal Hall, Kumari Cinema Hall, Gopi Krishna Cinema Hall and Guna Cinema Hall. Kathmandu also houses some international standard cinema theatres and multiplexes, such as QFX Cinemas, Cine De Chef, Fcube Cinemas, Q's Cinemas, Big Movies, BSR Movies and many more.
Music
Traditional Buddhist musical performance during Gunla
Kathmandu is the center of music and dance in Nepal, and these art forms are integral to understanding the city. Musical performances are organized in cultural venues. Music is a part of the traditional aspect of Kathmandu. Gunla is the traditional music festival according to Nepal Sambat. Newar music originated in Kathmandu. Furthermore, music from all over Nepal can be found in Kathmandu.
A number of hippies visited Kathmandu during the 1970s and introduced rock and roll, rock, and jazz to the city. Kathmandu is noted internationally for its jazz festival, popularly known as Jazzmandu. It is the only jazz festival in the Himalayan region and was established in March 2002. The festival attracts musicians from countries worldwide, such as Australia, Denmark, United States, Benin, and India.[80]
The city has been referenced in numerous songs, including works by Cat Stevens ('Katmandu', Mona Bone Jakon (1970)), Bob Seger ('Katmandu', Beautiful Loser (1975)), Rush ('A Passage to Bangkok', Pulling into Kathmandu; 2112, 1976), Krematorij ('Kathmandu', Three Springs (2000)), Fito Páez (Tráfico por Katmandú – "Traffic through Kathmandu") and Cavalcade ('Kathmandu Kid') 2019.
Cuisine
One of the typical Nepali meals Dal bhat in Kathmandu
The staple food of most people in Kathmandu is dal bhat. This consists of rice and lentil soup, generally served with vegetable curries, achar and sometimes Chutney. Momo, a type of Nepali version of Tibetan dumpling, has become prominent in Nepal with many street vendors and restaurants selling it. It is one of the most popular fast foods in Kathmandu. Various Nepali variants of momo including buff (i.e. buffalo) momo, chicken momo, and vegetarian momo are famous in Kathmandu.
Most of the cuisines found in Kathmandu are non-vegetarian. However, the practice of vegetarianism is not uncommon, and vegetarian cuisines can be found throughout the city. Consumption of beef is very uncommon and considered taboo in many places. Buff (meat of water buffalo) is very common. There is a strong tradition of buff consumption in Kathmandu, especially among Newars, which is not found in other parts of Nepal. Consumption of pork was considered taboo until a few decades ago. Due to the intermixing with Kirat cuisine from eastern Nepal, pork has found a place in Kathmandu dishes. A fringe population of devout Hindus and Muslims consider it taboo. The Muslims forbid eating buff as from Quran while Hindus eat all varieties except beef as they consider cow to be a goddess and symbol of purity. The chief lunch/snack for locals and visitors is mostly Momo or Chowmein.
Kathmandu had only one western-style restaurant in 1955.[81] A large number of restaurants in Kathmandu have since opened, catering Nepali cuisine, Tibetan cuisine, Chinese cuisine and Indian cuisine in particular. Many other restaurants have opened to accommodate locals, expatriates, and tourists. The growth of tourism in Kathmandu has led to culinary creativity and the development of hybrid foods to accommodate for tourists such as American chop suey, which is a sweet-and-sour sauce with crispy noodles with a fried egg commonly added on top and other westernized adaptations of traditional cuisine.[81] Continental cuisine can be found in selected places. International chain restaurants are rare, but some outlets of Pizza Hut and KFC have recently opened there. It also has several outlets of the international ice-cream chain Baskin-Robbins.[82]
Kathmandu has a larger proportion of tea drinkers than coffee drinkers. Tea is widely served but is extremely weak by western standards. It is richer and contains tea leaves boiled with milk, sugar, and spices. Alcohol is widely drunk, and there are numerous local variants of alcoholic beverages. Drinking and driving is illegal, and authorities have a zero-tolerance policy.[83] Ailaa and thwon (alcohol made from rice) are the alcoholic beverages of Kathmandu, found in all the local bhattis (alcohol serving eateries). Chhyaang, tongba (fermented millet or barley) and raksi are alcoholic beverages from other parts of Nepal which are found in Kathmandu. However, shops and bars in Kathmandu widely sell western and Nepali beers.

Festivals
Samyak, a Buddhist festival during which statues of Buddhas from the ancient monasteries are displayed together. Note the statue of Hanuman next to the Buddhas in the picture, a common example of religious harmony in Kathmandu.
Most of the fairs and festivals in Kathmandu originated in the Malla period or earlier. Traditionally, these festivals were celebrated by Newars. In recent years, these festivals have found wider participation from other Kathmanduites as well. As the capital of the Nepal, various national festivals are celebrated in Kathmandu. With mass migration to the city, the cultures of Khas from the west, Kirats from the east, Bon/Tibetan from the north, and Mithila from the south meet in the capital and mingle harmoniously. The festivities such as the Ghode (horse) Jatra, Indra Jatra, Dashain Durga Puja festivals, Shivratri and many more are observed by all Hindu and Buddhist communities of Kathmandu with devotional fervor and enthusiasm. Social regulation in the codes enacted incorporates Hindu traditions and ethics. These were followed by the Shah kings and previous kings, as devout Hindus and protectors of the Buddhist religion.

Cultural continuity has been maintained for centuries in the exclusive worship of goddesses and deities in Kathmandu and the rest of the country. These deities include the Ajima,[84] Taleju (or Tulja Bhavani or Taleju Bhawani)[85][86] and her other forms : Digu Taleju (or Degu Taleju)[87] and Kumari (the living goddess).[88] The artistic edifices have now become places of worship in the everyday life of the people, therefore a roster is maintained to observe annual festivals. There are 133 festivals held in the year.[89]
Some of the traditional festivals observed in Kathmandu, apart from those previously mentioned, are Bada Dashain, Tihar, Chhath, Maghe Sankranti, Nag Panchami, Janai Purnima, Pancha Dan, Teej/Rishi Panchami, Pahan Charhe, Jana Baha Dyah Jatra (White Machchhendranath Jatra), and Matatirtha Aunsi.[56]
Religions
Hinduism

Assumedly, together with the kingdom of Licchhavi (c. 400 to 750), Hinduism and the endogam social stratification of the caste was established in Kathmandu Valley. The Pashupatinath Temple, Changu Narayan Temple, and the Kasthamandap are of particular importance to Hindus. Other notable Hindu temples in Kathmandu and the surrounding valley include Bajrayogini Temple, Dakshinkali Temple, Guhyeshwari Temple, and the Shobha Bhagawati shrine.
The Bagmati river which flows through Kathmandu is considered a holy river both by Hindus and Buddhists, and many Hindu temples are on the banks of this river. The importance of the Bagmati also lies in the fact that Hindus are cremated on its banks, and Kirants are buried in the hills by its side. According to the Nepali Hindu tradition, the dead body must be dipped three times into the Bagmati before cremation. The chief mourner (usually the first son) who lights the funeral pyre must take a holy riverwater bath immediately after cremation. Many relatives who join the funeral procession also take bath in the Bagmati or sprinkle the holy water on their bodies at the end of cremation as the Bagmati is believed to purify people spiritually.
Buddhism
Buddhism was brought into Kathmandu with the arrival of Buddhist monks during the time of Buddha (c. 563 – 483 BCE[90]). They established a forest monastery in Sankhu. This monastery was renovated by Shakyas after they fled genocide from Virudhaka (r. 491–461 BCE).
During the Hindu Lichchavi era (c. 400 to 750), various monasteries and orders were created which successively led to the formation of Newar Buddhism, which is still practiced in the primary liturgical language of Hinduism, Sanskrit.
Legendary Princess Bhrikuti (7th-century) and artist Araniko (1245–1306 CE) from that tradition of Kathmandu valley played a significant role in spreading Buddhism in Tibet and China. There are over 108 traditional monasteries (Bahals and Baháʼís) in Kathmandu based on Newar Buddhism. Since the 1960s, the permanent Tibetan Buddhist population of Kathmandu has risen significantly so that there are now over fifty Tibetan Buddhist monasteries in the area. Also, with the modernization of Newar Buddhism, various Theravada Bihars have been established.
Islam
Jama Masjid, Ghantaghar
Muslims in Kathmandu pray to Allah on Friday (the day of Namaj) often going to the Jame Masjid in Ghantaghar, near Ratnapark.
Kirat Mundhum
Kirant Mundhum is one of the indigenous animistic practices of Nepal. It is practiced by the Kirat people. Some animistic aspects of Kirant beliefs, such as ancestor worship (worship of Ajima) are also found in Newars of Kirant origin. Ancient religious sites believed to be worshipped by ancient Kirats, such as Pashupatinath, Wanga Akash Bhairabh (Yalambar) and Ajima are now worshipped by people of all Dharmic religions in Kathmandu. Kirats who have migrated from other parts of Nepal to Kathmandu practice Mundhum in the city.[91]
Other religions
Sikhism is practiced primarily in Gurudwara at Kupundole. An earlier temple of Sikhism is also present in Kathmandu which is now defunct.
Jainism is practiced by a small community. A Jain temple is present in Gyaneshwar, where Jains practice their faith.
According to the records of the Spiritual Assembly of the Baháʼís of Nepal, there are approximately 300 followers of the Baháʼí Faith in Kathmandu valley. They have a national office in Shantinagar, Baneshwor. The Baháʼís also have classes for children at the National Centre and other localities in Kathmandu.
Islam is practiced in Kathmandu but Muslims are a minority, accounting for about 4.4% of the population of Nepal.[92]
It is said that in Kathmandu alone there are 170 Christian churches. Christian missionary hospitals, welfare organizations, and schools are also operating. Nepali citizens who served as soldiers in Indian and British armies, who had converted to Christianity while in service, on return to Nepal continue to practice their religion. They have contributed to the spread of Christianity and the building of churches in Nepal and in Kathmandu, in particular.[93][94]
Education
The oldest modern school in Nepal, the Durbar High School, and the oldest college, the Tri-Chandra College, are both in Kathmandu. The largest (according to number of students and colleges), the oldest and most distinguished university in Nepal the Tribhuvan University, located in Kirtipur. The second largest university, Kathmandu University (KU), is in Dhulikhel, Kavre on the outskirts of Kathmandu. It is the second oldest university in Nepal, established in November 1991.[95] Not surprisingly the best schools and colleges of Nepal are located in Kathmandu and its adjoining cities. Every year thousands of students from all over Nepal arrive at Kathmandu to get admission in the various schools and colleges. One of the key concerns of educationists and concerned citizens is the massive outflux of students from Nepal to outside Nepal for studies. Every year thousands of students apply for No Objection Certificates for studying abroad. Consultancy firms specializing in preparing students to go abroad can be found in all prominent locations. The reason for such an outflux range from perceived low quality of education, political instability, fewer opportunities in the job market, opportunities for earning while learning abroad and better job prospects with an international degree.
Healthcare
Healthcare in Kathmandu is the most developed in Nepal, and the city and surrounding valley is home to some of the best hospitals and clinics in the country. Bir Hospital is the oldest, established in July 1889 by Bir Shamsher Jang Bahadur Rana. Notable hospitals include Bir Hospital, Nepal Medical College and Teaching Hospital (Jorpati), Tribhuvan University Institute of Medicine (Teaching Hospital), Patan Hospital, Kathmandu Model Hospital, Scheer Memorial Hospital, Om Hospital, Norvic Hospital, Grande International Hospital, Nobel Hospital and many more.
The city is supported by specialist hospitals/clinics such as Shahid Shukraraj Tropical Hospital, Shahid Gangalal Foundation, Kathmandu Veterinary Hospital, Nepal Eye Hospital, Kanti Children's Hospital, Nepal International Clinic (Travel and Mountain Medicine Center), Neuro Center, Spinal Rehabilitation center and Bhaktapur Cancer Hospital. Most of the general hospitals are in the city center, although several clinics are elsewhere in Kathmandu district.
Tilganga Institute of Ophthalmology is an Ophthalmological hospital in Kathmandu. It pioneered the production of low cost intraocular lenses (IOLs), which are used in cataract surgery.[96] The team of Dr. Sanduk Ruit in Tilganga pioneered sutureless small-incision cataract surgery (SICS),[97][98] a technique which has been used to treat 4 million of the world's 20 million people with cataract blindness.
Medical colleges
Institute of Medicine, the central college of Tribhuvan University is the first medical college of Nepal and is in Maharajgunj, Kathmandu. It was established in 1972 and started to impart medical education from 1978. Other major institutions include Patan Academy of Health Sciences, Kathmandu Medical College, Nepal Medical College, KIST Medical College, Nepal Army Institute of Health Sciences, National Academy of Medical Sciences (NAMS) and Kathmandu University School of Medical Sciences (KUSMS), are also in or around Kathmandu.[99]
Economy
Central Bank of Nepal
The location and terrain of Kathmandu have played a significant role in the development of a stable economy which spans millennia. The city is in an ancient lake basin, with fertile soil and flat terrain. This geography helped form a society based on agriculture. This, combined with its location between India and China, helped establish Kathmandu as an important trading centre over the centuries. Kathmandu's trade is an ancient profession that flourished along an offshoot of the Silk Road which linked India and Tibet. From centuries past, Lhasa Newar merchants of Kathmandu have conducted trade across the Himalaya and contributed to spreading art styles and Buddhism across Central Asia.[100] Other traditional occupations are farming, metal casting, woodcarving, painting, weaving, and pottery.[101]
Kathmandu is the most important industrial and commercial centre in Nepal. The Nepal Stock Exchange, the head office of the national bank, the chamber of commerce, as well as head offices of national and international banks, telecommunication companies, the electricity authority, and various other national and international organizations are in Kathmandu. The major economic hubs are the New Road, Durbar Marg, Ason and Putalisadak.[101]
The economic output of the metropolitan area of around Rs. 550 billion approximately per year alone is worth more than one third of national GDP (nominal), while the per capita income of $2200 is approximately three times the national average.[102] Kathmandu exports handicrafts, artworks, garments, carpets, pashmina, paper; trade accounts for 21% of its revenues.[101][102] Manufacturing is also important and accounts for 19% of the revenue that Kathmandu generates. Garments and woolen carpets are the most notable manufactured products.[102] Other economic sectors in Kathmandu include agriculture (9%), education (6%), transport (6%), and hotels and restaurants (5%).[102] Kathmandu is famous for lokta paper and pashmina shawls.
Tourism
Hotel Shanker is one of the city's popular heritage hotels
Tourism is considered another important industry in Nepal. This industry started around 1950, as the country's political makeup changed and ended the country's isolation from the rest of the world. In 1956, air transportation was established and the Tribhuvan Highway, between Kathmandu and Raxaul (at India's border), was started. Separate organizations were created in Kathmandu to promote this activity; some of these include the Tourism Development Board, the Department of Tourism and the Civil Aviation Department. Furthermore, Nepal became a member of several international tourist associations. Establishing diplomatic relations with other nations further accentuated this activity. The hotel industry, travel agencies, training of tourist guides, and targeted publicity campaigns are the chief reasons for the remarkable growth of this industry in Nepal, and in Kathmandu in particular.[103] Since then, tourism in Nepal has thrived. It is the country's most important industry.[104] Tourism is a major source of income for most of the people in the city, with several hundred thousand visitors annually. Hindu and Buddhist pilgrims from all over the world visit Kathmandu's religious sites such as Pashupatinath, Swayambhunath, Boudhanath, Changunarayan and Budhanilkantha. From a mere 6,179 tourists in 1961/62, the number increased to 491,504 in 1999/2000. In economic terms, the foreign exchange registered 3.8% of the GDP in 1995/96 but then started declining. Following the end of the Maoist insurgency, there was a significant rise in the number of tourist arrivals, with 509,956 tourists recorded in 2009. Since then, tourism has improved as the country transitioned into a republic. The high level of tourism is attributed to the natural grandeur of the Himalayas and the rich cultural heritage of the country.[103]
Hyatt Regency, Kathmandu
The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel that was coined to rhyme with Thamel.[105] Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveller's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Ason is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.
With the opening of the tourist industry after the change in the political scenario of Nepal in 1950, the hotel industry drastically improved.[106] Now Kathmandu boasts several luxuries such as the Hyatt Regency, Dwarika's, Hotel Yak & Yeti, The Everest Hotel, Hotel Radisson, Hotel De L'Annapurna, The Malla Hotel, Shangri-La Hotel (not operated by the Shangri-La Hotel Group) and Hotel Shanker. There are several four-star hotels such as Akama Hotel, Hotel Vaishali, Hotel Narayani, The Blue Star and Grand Hotel. The Garden Hotel, Hotel Ambassador, and Aloha Inn are among the three-star hotels in Kathmandu. Hotels like Hyatt Regency, De L'Annapurna, and Yak & Yeti are among the five-star hotels with casinos as well.[107]
Transport

Road
The total length of roads in Nepal is recorded to be 17,182 km (10,676 mi), as of 2003–04. This fairly large network has helped the economic development of the country, particularly in the fields of agriculture, horticulture, vegetable farming, industry and also tourism.[108] In view of the hilly terrain, transportation takes place in Kathmandu are mainly by road and air. Kathmandu is connected by the Tribhuvan Highway to the south connecting India, Prithvi Highway to the west and Araniko Highway to the north connecting China. The BP Highway connects Kathmandu to the eastern part of Nepal through Sindhuli.[109] The fast-track is under construction which will be the shortest route to connect Terai with the valley.[110]
Sajha Yatayat provides regular bus services throughout Kathmandu and the surrounding valley. Other bus companies including micro-bus companies operate several unscheduled routes. Trolleybusses used to operate on the route between Tripureshwor and Suryabinayak on a 13-kilometer route.
Air
The main international airport serving Kathmandu valley is the Tribhuvan International Airport, about 6 kilometres (3.7 mi) from the city centre and is operated by the Civil Aviation Authority of Nepal.[111] It has two terminals, one domestic and one international. At present, it connects 30 cities around the globe in Europe, Asia and the Middle East such as Istanbul, Delhi, Mumbai, Bangalore, Kolkata, Singapore, Bangkok, Kuala Lumpur, Dhaka, Paro, Lhasa, Chengdu, Guangzhou and Hong Kong.[111] Since 2013, Turkish Airlines connects Istanbul to Kathmandu.[112] Oman Air also connects Muscat to Kathmandu since 2010.[113] Nepal Airlines started flying to Tokyo-Narita from March 2, 2020.[114] Regionally, several Nepali airlines operate from the city, inc

How is everybody?
I would like to thank Remco for his kindness, in gifting me a pro account. I still have no words to express the magnitude of my gratitude... Thanks again, Remco!
Comet ATLAS C/2019 Y4, discovered in December 2019, has been quickly increasing in brightness over the last few months, and many of us hope that trend will continue; past projections put it as reaching naked-eye brightness this April or May. However, it's brightness has recently plateaued around magnitude +8. That and an elongated nucleus suggest that it might be disintegrating.
It was likely about magnitude +8 when I photographed it last night, April 9th, near Star 42 Camelopardalis. I'm not sure what the faint nebulosity is to the lower left of the comet: either Dark Nebula HSVMT 25, integrated flux nebula (IFN), or it's simply an artifact. Galaxy NGC 2366 is also apparent in the upper right corner.
Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 50 x 30 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker (used comet stacking mode so stars and comet were stacked separately and then combined), editing with Astro Pixel Processor and GIMP, taken in the 30 minute-window between astronomic dusk and the rise of the 93% illuminated moon on April 9, 2020 under Bortle 3/4 skies.
At a relatively bright magnitude of +8, M104 is easily seen through small telescopes. The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns. The galaxy is 50,000 light-years across and is located 28 million light-years from Earth.
Hubble easily resolves M104's rich system of globular clusters, estimated to be nearly 2,000 in number -- 10 times as many as orbit our Milky Way galaxy. The ages of the clusters are similar to the clusters in the Milky Way, ranging from 10-13 billion years old. Embedded in the bright core of M104 is a smaller disk, which is tilted relative to the large disk. X-ray emission suggests that there is material falling into the compact core, where a 1-billion-solar-mass black hole resides.

...the Moon.
That explains the idea of angular size and ambiguity of apparent magnitude :) But it doesn't explain, why StarWalk app messes with altitude readings... I don't believe this program anymore and I need a marine sextant.
And - I had just noticed this! - the Moon moves! Not only it moves "along with the sky" but it also moves by itself eastward. When there is such a nice reference as Venus it becomes obvious.

On March 11, 2011, at 2:46 p.m. local time (05:46 Universal Time, or UTC), a magnitude 8.9 earthquake struck off the east coast of Japan, at 38.3 degrees North latitude and 142.4 degrees East longitude. The epicenter was 130 kilometers (80 miles) east of Sendai, and 373 kilometers (231 miles) northeast of Tokyo. If the initial measurements are confirmed, it will be the world's fifth largest earthquake since 1900.
This map shows the location of the March 11 earthquake, as well as the foreshocks (dotted lines) and aftershocks (solid lines). The size of each circle represents the magnitude of the associated quake or shock. The map also includes land elevation data from NASA's Shuttle Radar Topography Mission and ocean bathymetry data from the British Oceanographic Data Center.
According to the U.S. Geological Survey (USGS), the earthquake occurred at a depth of 24.4 kilometers (15.2 miles) beneath the seafloor. The March 11 earthquake was preceded by a series of large foreshocks on March 9, including an M7.2 event. USGS reported that the earthquakes "occurred as a result of thrust faulting on or near the subduction zone interface plate boundary between the Pacific and North America plates."
The March 11 quake sent tsunami waves rushing into the coast of Japan and rippling out across the entire Pacific basin. Crescent-shaped coasts and harbors, such as those near Sendai, can play a role in focusing the waves as they approach the shore. Also, the land elevation is low and flat along much of the Japanese coast west and south of the earthquake epicenter, leaving many areas particularly vulnerable to tsunamis.
The Japan Meteorological Agency reported maximum tsunami heights of 4.1 meters at Kamaishi at 3:21 p.m. (06:21 UTC), 7.3 meters at 3:50 p.m. (06:50 UTC) at the Soma station, and 4.2 meters at 4:52 p.m. (07:52 UTC) at Oarai.
The U.S. Pacific Tsunami Warning Center (PTWC) reported a wave with maximum height of 2.79 meters (9.2 feet) at an observing station at Hanasaki, Hokkaido, at 3:57 p.m. local time (06:57 UTC). Other PTWC reports of tsunami waves include:
1.27 meters (4.2 feet) at 10:48 UTC at Midway Island
1.74 meters (5.7 feet) at 13:72 UTC at Kahului, Maui, Hawaii
1.41 meters (4.6 feet) at 14:09 UTC at Hilo, Hawaii
0.69 meters (2.3 feet) at 15:42 UTC in Vanuatu
1.88 meters (6.2 feet) at 16:54 UTC at Port San Luis, California
2.02 meters (6.6 feet) at 16:57 UTC at Crescent City, California

On Tuesday a 7.1 magnitude earthquake struck Mexico City.
We were just recovering from the one that struck the coast in Chiapas 2 weeks ago. (The strongest to hit in a century, registered 8.2 on the Richter scale).
At least 278 people are dead, including 32 children.
Thousands injured and hundreds still missing. Rescuers from all over the world are working around the clock to find victims under 44 collapsed buildings.
Many parts of Mexico City, Puebla, Morelos, Chiapas and Oaxaca are devastated. Mexico needs your help. No matter how small, everything helps. If you're looking for a way to contribute, please consider the following organizations:

Giving support and thank you Kira Balestra for share this! ♥
This is really important, this time to happen in Mexico, other times to been in other places, but at some point we can happen to anyone, given that this planet is slowly crumbling and is our responsibility, and for that very reason, I feel it is our duty to contribute our help in any way, however small, it is always help, the ugly thing would be to sit idly by and look the other way.
It costs nothing, and the effect is immense.
Thanks to all those who in one way or another, collaborate in this or in the causes that are, but the fact is to help.
On April 9, 2013 at 11:52 GMT, a magnitude 6.3 earthquake hit southwestern Iran's Bushehr province near the town of Kaki. Preliminary information is that several villages have been destroyed and many people have died, as reported by BBC News. This perspective view of the region was acquired Nov. 17, 2012, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft. The location of the earthquake's epicenter is marked with a yellow star. Vegetation is displayed in red; the vertical exaggeration of the topography is 2X. The image is centered near 28.5 degrees north latitude, 51.6 degrees east longitude.
With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.
The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.
The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
More information about ASTER is available at asterweb.jpl.nasa.gov/.

By the massive earthquakes of Magnitude 9 and surreal massive tsunamis, more than 10,000 people are still missing…even now… It has been 16 days already since the disaster happened. What makes it worse is that water at the reactors of Fukushima Nuclear Plants started to leak, and it’s contaminating the ocean, air and water molecule of surrounding areas.
Human wisdom has not been able to do much to solve the problem, but we are only trying to cool down the anger of radioactive materials in the reactors by discharging water to them.
Is there really nothing else to do?
I think there is. During over twenty year research of hado measuring and water crystal photographic technology, I have been witnessing that water can turn positive when it receives pure vibration of human prayer no matter how far away it is.
Energy formula of Albert Einstein, E=MC2 really means that Energy = number of people and the square of people’s consciousness.
Now is the time to understand the true meaning. Let us all join the prayer ceremony as fellow citizens of the planet earth. I would like to ask all people, not just in Japan, but all around the world to please help us to find a way out the crisis of this planet!!
The prayer procedure is as follows.
Name of ceremony:
“Let’s send our thoughts of love and gratitude to all water in the nuclear plants in Fukushima”
Day and Time:
Begin : March 31st, 2011 (Thursday)
12:00 noon in each time zone
End : April 10th
Please say the following phrase:
“The water of Fukushima Nuclear Plant, we are sorry to make you suffer.
Please forgive us. We thank you, and we love you.”
Please say it aloud or in your mind. Repeat it three times as you put your hands together in a prayer position. Please offer your sincere prayer.
Thank you very much from my heart.
With love and gratitude,
Masaru Emoto

thank you Aruna for sharing !
The Andromeda Galaxy or M31 as captured in a stack of fifty-four images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This photo also shows Andromeda's two satellite galaxies, M32 and M110 (see image notes for the locations, M110 is the small elliptical galaxy slightly below center).
This photo was taken using a 50mm Nikkor AF-D lens on a Nikon D5100 DSLR and it is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size).
With the aid of the Cartes du Ciel star charting software (highly recommended free download) and with an examination of the area surrounding M110 I've determined that the limiting magnitude in this photo is around 14.5 (stars nearing the 14th magnitude are clearly shown, fainter than that are more difficult). There is also a definite halo around the small satellite galaxy M32, a detail which was not that apparent in my earlier post.
The brightest star in this photo (above center) is Nu Andromeda at magnitude 4.5 and it is located just over one degree from the center of the Andromeda Galaxy. One degree is just about twice the apparent size of the full moon, so you can see that the Andromeda Galaxy (as recorded in this photo) is several times the size of the full moon.
Captured on September 28 and 29 between 11:34PM and 12:28AM PDT with a Nikon D5100 DSLR (ISO 4000, 25 second exposure x 54) and a 50mm AF-D Nikkor lens set to aperture f/2.8. Image stack created with DeepSkyStacker using 54 image frames combined with 27 dark frames (no flats or bias).

This is the 8th magnitude Messier galaxy M49 in Virgo, a bright elliptical. It was discovered by Charles Messier in 1771. It is accompanied by two bright galaxies to the left (east) — the 10th magnitude face-on spiral NGC 4535 at top left, and the 9th magnitude edge-on spiral NGC 4560 at bottom left. Together they form a fine trio of three different and distinct galaxy types and morphologies.
Many other faint galaxies from the NGC, UGC and PGC catalogues populate the field.
Technical:
This is a stack of 11 x 6 minute exposures with the Askar APO120 refractor at f/7 with its 1x Flattener, and the Canon R5 at ISO 800. On the Astro-Physics AP400 mount and guided with the MGEN3 guider. Taken from home on a very fine night in April 2025.

Don't abandon HOPE !!
A tramp abroad
A great and priceless thing is a new interest! How
it takes possession of a man! how it clings to him,
how it rides him! I strode onward from the Schwarenbach
hostelry a changed man, a reorganized personality.
I walked into a new world, I saw with new eyes.
I had been looking aloft at the giant show-peaks only as
things to be worshiped for their grandeur and magnitude,
and their unspeakable grace of form; I looked up at
them now, as also things to be conquered and climbed.
My sense of their grandeur and their noble beauty
was neither lost nor impaired; I had gained a new
interest in the mountains without losing the old ones.
I followed the steep lines up, inch by inch, with my eye,
and noted the possibility or impossibility of following
them with my feet. When I saw a shining helmet of ice
projecting above the clouds, I tried to imagine I saw
files of black specks toiling up it roped together with a
gossamer thread.
We skirted the lonely little lake called the Daubensee,
and presently passed close by a glacier on the right
--a thing like a great river frozen solid in its flow
and broken square off like a wall at its mouth.
I had never been so near a glacier before.
Here we came upon a new board shanty, and found some men
engaged in building a stone house; so the Schwarenbach was
soon to have a rival. We bought a bottle or so of beer here;
at any rate they called it beer, but I knew by the price
that it was dissolved jewelry, and I perceived by the
taste that dissolved jewelry is not good stuff to drink.
We were surrounded by a hideous desolation. We stepped
forward to a sort of jumping-off place, and were confronted
by a startling contrast: we seemed to look down into fairyland.
Two or three thousand feet below us was a bright green level,
with a pretty town in its midst, and a silvery stream
winding among the meadows; the charming spot was walled
in on all sides by gigantic precipices clothed with pines;
and over the pines, out of the softened distances,
rose the snowy domes and peaks of the Monte Rosa region.
How exquisitely green and beautiful that little valley
down there was! The distance was not great enough to
obliterate details, it only made them little, and mellow,
and dainty, like landscapes and towns seen through the
wrong end of a spy-glass.
Right under us a narrow ledge rose up out of the valley,
with a green, slanting, bench-shaped top, and grouped
about upon this green-baize bench were a lot of black
and white sheep which looked merely like oversized worms.
The bench seemed lifted well up into our neighborhood,
but that was a deception--it was a long way down to it.
We began our descent, now, by the most remarkable road I
have ever seen. It wound its corkscrew curves down the face
of the colossal precipice--a narrow way, with always
the solid rock wall at one elbow, and perpendicular
nothingness at the other. We met an everlasting procession
of guides, porters, mules, litters, and tourists climbing
up this steep and muddy path, and there was no room
to spare when you had to pass a tolerably fat mule.
I always took the inside, when I heard or saw the
mule coming, and flattened myself against the wall.
I preferred the inside, of course, but I should have had
to take it anyhow, because the mule prefers the outside.
A mule's preference--on a precipice--is a thing to
be respected. Well, his choice is always the outside.
His life is mostly devoted to carrying bulky panniers
and packages which rest against his body--therefore he
is habituated to taking the outside edge of mountain paths,
to keep his bundles from rubbing against rocks or banks
on the other. When he goes into the passenger business he
absurdly clings to his old habit, and keeps one leg of his
passenger always dangling over the great deeps of the lower
world while that passenger's heart is in the highlands,
so to speak. More than once I saw a mule's hind foot
cave over the outer edge and send earth and rubbish into
the bottom abyss; and I noticed that upon these occasions
the rider, whether male or female, looked tolerably unwell.
There was one place where an eighteen-inch breadth of
light masonry had been added to the verge of the path,
and as there was a very sharp turn here, a panel of fencing
had been set up there at some time, as a protection.
This panel was old and gray and feeble, and the light
masonry had been loosened by recent rains. A young
American girl came along on a mule, and in making the turn
the mule's hind foot caved all the loose masonry and one
of the fence-posts overboard; the mule gave a violent lurch
inboard to save himself, and succeeded in the effort,
but that girl turned as white as the snows of Mont Blanc
for a moment.
The path was simply a groove cut into the face of
the precipice; there was a four-foot breadth of solid rock
under the traveler, and four-foot breadth of solid rock
just above his head, like the roof of a narrow porch;
he could look out from this gallery and see a sheer
summitless and bottomless wall of rock before him,
across a gorge or crack a biscuit's toss in width
--but he could not see the bottom of his own precipice
unless he lay down and projected his nose over the edge.
I did not do this, because I did not wish to soil my clothes.
Every few hundred yards, at particularly bad places,
one came across a panel or so of plank fencing; but they
were always old and weak, and they generally leaned
out over the chasm and did not make any rash promises
to hold up people who might need support. There was one
of these panels which had only its upper board left;
a pedestrianizing English youth came tearing down the path,
was seized with an impulse to look over the precipice,
and without an instant's thought he threw his weight
upon that crazy board. It bent outward a foot! I never
made a gasp before that came so near suffocating me.
The English youth's face simply showed a lively surprise,
but nothing more. He went swinging along valleyward again,
as if he did not know he had just swindled a coroner by the
closest kind of a shave.
The Alpine litter is sometimes like a cushioned box
made fast between the middles of two long poles,
and sometimes it is a chair with a back to it and a support
for the feet. It is carried by relays of strong porters.
The motion is easier than that of any other conveyance.
We met a few men and a great many ladies in litters;
it seemed to me that most of the ladies looked pale
and nauseated; their general aspect gave me the idea
that they were patiently enduring a horrible suffering.
As a rule, they looked at their laps, and left the scenery
to take care of itself.
But the most frightened creature I saw, was a led horse
that overtook us. Poor fellow, he had been born and reared
in the grassy levels of the Kandersteg valley and had
never seen anything like this hideous place before.
Every few steps he would stop short, glance wildly out from
the dizzy height, and then spread his red nostrils wide
and pant as violently as if he had been running a race;
and all the while he quaked from head to heel as with
a palsy. He was a handsome fellow, and he made a fine
statuesque picture of terror, but it was pitiful to see
him suffer so.
This dreadful path has had its tragedy. Baedeker, with his
customary over-terseness, begins and ends the tale thus:
"The descent on horseback should be avoided.
In 1861 a Comtesse d'Herlincourt fell from her saddle
over the precipice and was killed on the spot."
We looked over the precipice there, and saw the monument
which commemorates the event. It stands in the bottom
of the gorge, in a place which has been hollowed out of
the rock to protect it from the torrent and the storms.
Our old guide never spoke but when spoken to, and then
limited himself to a syllable or two, but when we asked
him about this tragedy he showed a strong interest
in the matter. He said the Countess was very pretty,
and very young--hardly out of her girlhood, in fact.
She was newly married, and was on her bridal tour.
The young husband was riding a little in advance; one guide
was leading the husband's horse, another was leading the
bride's.
The old man continued:
"The guide that was leading the husband's horse happened
to glance back, and there was that poor young thing sitting
up staring out over the precipice; and her face began
to bend downward a little, and she put up her two hands
slowly and met it--so,--and put them flat against her
eyes--so--and then she sank out of the saddle, with a
sharp shriek, and one caught only the flash of a dress,
and it was all over."
Then after a pause:
"Ah, yes, that guide saw these things--yes, he saw them all.
He saw them all, just as I have told you."
After another pause:
"Ah, yes, he saw them all. My God, that was ME.
I was that guide!"
This had been the one event of the old man's life; so one
may be sure he had forgotten no detail connected with it.
We listened to all he had to say about what was done and what
happened and what was said after the sorrowful occurrence,
and a painful story it was.
When we had wound down toward the valley until we were about
on the last spiral of the corkscrew, Harris's hat blew
over the last remaining bit of precipice--a small cliff
a hundred or hundred and fifty feet high--and sailed down
toward a steep slant composed of rough chips and fragments
which the weather had flaked away from the precipices.
We went leisurely down there, expecting to find it without
any trouble, but we had made a mistake, as to that.
We hunted during a couple of hours--not because the old
straw hat was valuable, but out of curiosity to find out
how such a thing could manage to conceal itself in open
ground where there was nothing left for it to hide behind.
When one is reading in bed, and lays his paper-knife down,
he cannot find it again if it is smaller than a saber;
that hat was as stubborn as any paper-knife could have been,
and we finally had to give it up; but we found a fragment
that had once belonged to an opera-glass, and by digging
around and turning over the rocks we gradually collected
all the lenses and the cylinders and the various odds
and ends that go to making up a complete opera-glass.
We afterward had the thing reconstructed, and the owner
can have his adventurous lost-property by submitting
proofs and paying costs of rehabilitation. We had hopes
of finding the owner there, distributed around amongst
the rocks, for it would have made an elegant paragraph;
but we were disappointed. Still, we were far from
being disheartened, for there was a considerable area
which we had not thoroughly searched; we were satisfied he
was there, somewhere, so we resolved to wait over a day at
Leuk and come back and get him.
Then we sat down to polish off the perspiration and
arrange about what we would do with him when we got him.
Harris was for contributing him to the British Museum;
but I was for mailing him to his widow. That is the difference
between Harris and me: Harris is all for display, I am
all for the simple right, even though I lose money by it.
Harris argued in favor of his proposition against mine,
I argued in favor of mine and against his. The discussion
warmed into a dispute; the dispute warmed into a quarrel.
I finally said, very decidedly:
"My mind is made up. He goes to the widow."
Harris answered sharply:
"And MY mind is made up. He goes to the Museum."
I said, calmly:
"The museum may whistle when it gets him."
Harris retorted:
"The widow may save herself the trouble of whistling,
for I will see that she never gets him."
After some angry bandying of epithets, I said:
"It seems to me that you are taking on a good many airs
about these remains. I don't quite see what YOU'VE got
to say about them?"
"I? I've got ALL to say about them. They'd never have
been thought of if I hadn't found their opera-glass. The
corpse belongs to me, and I'll do as I please with him."
I was leader of the Expedition, and all discoveries
achieved by it naturally belonged to me. I was entitled
to these remains, and could have enforced my right;
but rather than have bad blood about the matter,
I said we would toss up for them. I threw heads and won,
but it was a barren victory, for although we spent all
the next day searching, we never found a bone. I cannot
imagine what could ever have become of that fellow.
The town in the valley is called Leuk or Leukerbad.
We pointed our course toward it, down a verdant slope
which was adorned with fringed gentians and other flowers,
and presently entered the narrow alleys of the outskirts
and waded toward the middle of the town through liquid
"fertilizer." They ought to either pave that village or
organize a ferry.
Harris's body was simply a chamois-pasture; his person
was populous with the little hungry pests; his skin,
when he stripped, was splotched like a scarlet-fever patient's;
so, when we were about to enter one of the Leukerbad inns,
and he noticed its sign, "Chamois Hotel," he refused
to stop there. He said the chamois was plentiful enough,
without hunting up hotels where they made a specialty of it.
I was indifferent, for the chamois is a creature that will
neither bite me nor abide with me; but to calm Harris,
we went to the Ho^tel des Alpes.
At the table d'ho^te, we had this, for an incident.
A very grave man--in fact his gravity amounted to solemnity,
and almost to austerity--sat opposite us and he was
"tight," but doing his best to appear sober. He took up
a CORKED bottle of wine, tilted it over his glass awhile,
then set it out of the way, with a contented look, and went
on with his dinner.
Presently he put his glass to his mouth, and of course
found it empty. He looked puzzled, and glanced furtively
and suspiciously out of the corner of his eye at a
benignant and unconscious old lady who sat at his right.
Shook his head, as much as to say, "No, she couldn't have
done it." He tilted the corked bottle over his glass again,
meantime searching around with his watery eye to see
if anybody was watching him. He ate a few mouthfuls,
raised his glass to his lips, and of course it was
still empty. He bent an injured and accusing side-glance
upon that unconscious old lady, which was a study to see.
She went on eating and gave no sign. He took up his glass
and his bottle, with a wise private nod of his head,
and set them gravely on the left-hand side of his plate
--poured himself another imaginary drink--went to work
with his knife and fork once more--presently lifted
his glass with good confidence, and found it empty,
as usual.
This was almost a petrifying surprise. He straightened
himself up in his chair and deliberately and sorrowfully
inspected the busy old ladies at his elbows, first one and
then the other. At last he softly pushed his plate away,
set his glass directly in front of him, held on to it
with his left hand, and proceeded to pour with his right.
This time he observed that nothing came. He turned the
bottle clear upside down; still nothing issued from it;
a plaintive look came into his face, and he said, as if
to himself,
"'IC! THEY'VE GOT IT ALL!" Then he set the bottle down,
resignedly, and took the rest of his dinner dry.
It was at that table d'ho^te, too, that I had under inspection
the largest lady I have ever seen in private life.
She was over seven feet high, and magnificently proportioned.
What had first called my attention to her, was my stepping
on an outlying flange of her foot, and hearing, from up
toward the ceiling, a deep "Pardon, m'sieu, but you encroach!"
That was when we were coming through the hall, and the place
was dim, and I could see her only vaguely. The thing
which called my attention to her the second time was,
that at a table beyond ours were two very pretty girls,
and this great lady came in and sat down between them
and me and blotted out my view. She had a handsome face,
and she was very finely formed--perfected formed,
I should say. But she made everybody around her look trivial
and commonplace. Ladies near her looked like children,
and the men about her looked mean. They looked like failures;
and they looked as if they felt so, too. She sat with
her back to us. I never saw such a back in my life.
I would have so liked to see the moon rise over it.
The whole congregation waited, under one pretext or another,
till she finished her dinner and went out; they wanted to see
her at full altitude, and they found it worth tarrying for.
She filled one's idea of what an empress ought to be,
when she rose up in her unapproachable grandeur and moved
superbly out of that place.
We were not at Leuk in time to see her at her heaviest weight.
She had suffered from corpulence and had come there to get
rid of her extra flesh in the baths. Five weeks of soaking
--five uninterrupted hours of it every day--had accomplished
her purpose and reduced her to the right proportions.
Those baths remove fat, and also skin-diseases. The
patients remain in the great tanks for hours at a time.
A dozen gentlemen and ladies occupy a tank together,
and amuse themselves with rompings and various games.
They have floating desks and tables, and they read or lunch
or play chess in water that is breast-deep. The tourist
can step in and view this novel spectacle if he chooses.
There's a poor-box, and he will have to contribute.
There are several of these big bathing-houses, and you can
always tell when you are near one of them by the romping
noises and shouts of laughter that proceed from it.
The water is running water, and changes all the time,
else a patient with a ringworm might take the bath with only
a partial success, since, while he was ridding himself of
the ringworm, he might catch the itch.
The next morning we wandered back up the green valley,
leisurely, with the curving walls of those bare and
stupendous precipices rising into the clouds before us.
I had never seen a clean, bare precipice stretching up
five thousand feet above me before, and I never shall
expect to see another one. They exist, perhaps, but not
in places where one can easily get close to them.
This pile of stone is peculiar. From its base to the
soaring tops of its mighty towers, all its lines and
all its details vaguely suggest human architecture.
There are rudimentary bow-windows, cornices, chimneys,
demarcations of stories, etc. One could sit and stare up
there and study the features and exquisite graces of this
grand structure, bit by bit, and day after day, and never
weary his interest. The termination, toward the town,
observed in profile, is the perfection of shape.
It comes down out of the clouds in a succession of rounded,
colossal, terracelike projections--a stairway for the gods;
at its head spring several lofty storm-scarred towers,
one after another, with faint films of vapor curling
always about them like spectral banners. If there were
a king whose realms included the whole world, here would
be the place meet and proper for such a monarch. He would
only need to hollow it out and put in the electric light.
He could give audience to a nation at a time under its roof.
Our search for those remains having failed, we inspected with
a glass the dim and distant track of an old-time avalanche
that once swept down from some pine-grown summits behind
the town and swept away the houses and buried the people;
then we struck down the road that leads toward the Rhone,
to see the famous Ladders. These perilous things are
built against the perpendicular face of a cliff two or
three hundred feet high. The peasants, of both sexes,
were climbing up and down them, with heavy loads on
their backs. I ordered Harris to make the ascent, so I
could put the thrill and horror of it in my book, and he
accomplished the feat successfully, though a subagent,
for three francs, which I paid. It makes me shudder yet
when I think of what I felt when I was clinging there
between heaven and earth in the person of that proxy.
At times the world swam around me, and I could hardly keep
from letting go, so dizzying was the appalling danger.
Many a person would have given up and descended, but I stuck
to my task, and would not yield until I had accomplished it.
I felt a just pride in my exploit, but I would not
have repeated it for the wealth of the world. I shall
break my neck yet with some such foolhardy performance,
for warnings never seem to have any lasting effect on me.
When the people of the hotel found that I had been
climbing those crazy Ladders, it made me an object of
considerable attention.

Kathmandu (/ˌkætmænˈduː/;[2] Nepali: काठमाडौँ, Nepali pronunciation: [ˈkaʈʰmaɳɖu]) is the capital and largest city of Nepal, with a population of around 1 million. Also known as the city of temples, the city stands at an elevation of approximately 1,400 metres (4,600 feet) above sea level in the bowl-shaped Kathmandu valley in central Nepal. The valley was historically called the "Nepal Mandala" and has been the home of the Newar people, a cosmopolitan urban civilization in the Himalayan foothills. The city was the royal capital of the Kingdom of Nepal and hosts palaces, mansions and gardens of the Nepalese aristocracy. It has been home to the headquarters of the South Asian Association for Regional Cooperation (SAARC) since 1985. Today, it is the seat of government of the Nepalese republic, established in 2008, and is part of the Bagmati Province.
Kathmandu is and has been for many years the centre of Nepal's history, art, culture, and economy. It has a multi-ethnic population within a Hindu and Buddhist majority. Religious and cultural festivities form a major part of the lives of people residing in Kathmandu. Tourism is an important part of the economy in the city. In 2013, Kathmandu was ranked third among the top ten upcoming travel destinations in the world by TripAdvisor, and ranked first in Asia. The city is considered the gateway to the Nepalese Himalayas and is home to several world heritage sites: the Durbar Square, Swayambhunath, Boudhanath and Pashupatinath. Kathmandu valley is growing at 4 percentange per year according to the World Bank in 2010, making it one of the fastest-growing metropolitan areas in South Asia, and the first region in Nepal to face the unprecedented challenges of rapid urbanization and modernization at a metropolitan scale.
Historic areas of Kathmandu were severely damaged by a 7.8 magnitude earthquake in April 2015. Some of the buildings have been restored while some remain in the process of reconstruction.
Etymology
The indigenous Newari term for Kathmandu valley is Yen. The Nepali name Kathmandu comes from Kasthamandap, which stood in the Durbar Square. In Sanskrit, Kāṣṭha (Sanskrit: काष्ठ) means "Wood" and Maṇḍapa (Sanskrit: मण्डप) means "Pavilion". This public pavilion, also known as Maru Satta in Newari, was rebuilt in 1596 by Biseth in the period of King Laxmi Narsingh Malla. The three-storey structure was made entirely of wood and used no iron nails nor supports. According to legends, all the timber used to build the pagoda was obtained from a single tree.[4] The structure collapsed during a major earthquake in April 2015.
The colophons of ancient manuscripts, dated as late as the 20th century, refer to Kathmandu as Kāṣṭhamaṇḍap Mahānagar in Nepal Mandala. Mahānagar means "great city". The city is called Kāṣṭhamaṇḍap in a vow that Buddhist priests still recite to this day. Thus, Kathmandu is also known as Kāṣṭhamaṇḍap. During medieval times, the city was sometimes called Kāntipur (Sanskrit: कान्तिपुर). This name is derived from two Sanskrit words – Kānti and Pur. Kānti is a word that stands for "beauty" and is mostly associated with light and Pur means place, thus giving it the meaning, "City of light".
Among the indigenous Newar people, Kathmandu is known as Yeṃ Deśa (Nepal Bhasa: येँ देश), and Patan and Bhaktapur are known as Yala Deśa (Nepal Bhasa: यल देश) and Khwopa Deśa (Nepal Bhasa: ख्वप देश) respectively.[5] "Yen" is the shorter form of Yambu (Nepal Bhasa: यम्बु), which originally referred to the northern half of Kathmandu. The older northern settlements were referred to as Yambi while the southern settlement was known as Yangala.[6][7]
The spelling "Katmandu" was often used in older English-language text. More recently, however, the spelling "Kathmandu" has become more common in English.
History
Archaeological excavations in parts of Kathmandu have found evidence of ancient civilizations. The oldest of these findings is a statue, found in Maligaon, that was dated at 185 AD.[9] The excavation of Dhando Chaitya uncovered a brick with an inscription in Brahmi script. Archaeologists believe it is two thousand years old.[9] Stone inscriptions are a ubiquitous element at heritage sites and are key sources for the history of Nepal.
The earliest Western reference to Kathmandu appears in an account of Jesuit Fathers the Portuguese Jesuit, Fr. Joao Cabral who passed through the Kathmandu Valley in the spring of 1628 [10]and was received graciously by the king of that time, probably King Lakshminarasimha Malla of Kathmandu on their way from Tibet to India,[11] and reported that they reached "Cadmendu", the capital of Nepal kingdom.[12]
Ancient history
The ancient history of Kathmandu is described in its traditional myths and legends. According to Swayambhu Purana, present-day Kathmandu was once a huge and deep lake named "Nagdaha", as it was full of snakes. The lake was cut drained by Bodhisatwa Manjushree with his sword, and the water was evacuated out from there. He then established a city called Manjupattan, and made Dharmakar the ruler of the valley land. After some time, a demon named Banasur closed the outlet, and the valley again turned into a lake. Then Lord Krishna came to Nepal, killed Banasur, and again drained out the water. He brought some Gopals along with him and made Bhuktaman the king of Nepal.[13][14][15]
Kotirudra Samhita of Shiva Purana, Chapter 11, Shloka 18 refers to the place as Nayapala city, which was famous for its Pashupati Shivalinga. The name Nepal probably originates from this city Nayapala.
Very few historical records exists of the period before medieval Licchavi rulers. According to Gopalraj Vansawali, a genealogy of Nepali monarchy, the rulers of Kathmandu Valley before the Licchavis were Gopalas, Mahispalas, Aabhirs, Kiratas, and Somavanshi.[15][16] The Kirata dynasty was established by Yalamber. During the Kirata era, a settlement called Yambu existed in the northern half of old Kathmandu. In some of the Sino-Tibetan languages, Kathmandu is still called Yambu. Another smaller settlement called Yengal was present in the southern half of old Kathmandu, near Manjupattan. During the reign of the seventh Kirata ruler, Jitedasti, Buddhist monks entered Kathmandu valley and established a forest monastery at Sankhu.

Licchavi era
The Licchavis from the Indo-Gangetic plain migrated north and defeated the Kiratas, establishing the Licchavi dynasty, circa 400 AD. During this era, following the genocide of Shakyas in Lumbini by Virudhaka, the survivors migrated north and entered the forest monastery lora masquerading as Koliyas. From Sankhu, they migrated to Yambu and Yengal (Lanjagwal and Manjupattan) and established the first permanent Buddhist monasteries of Kathmandu. This created the basis of Newar Buddhism, which is the only surviving Sanskrit-based Buddhist tradition in the world.[17] With their migration, Yambu was called Koligram and Yengal was called Dakshin Koligram[18] during most of the Licchavi era.[19]
Eventually, the Licchavi ruler Gunakamadeva merged Koligram and Dakshin Koligram, founding the city of Kathmandu.[19] The city was designed in the shape of Chandrahrasa, the sword of Manjushri. The city was surrounded by eight barracks guarded by Ajimas. One of these barracks is still in use at Bhadrakali (in front of Singha Durbar). The city served as an important transit point in the trade between India and Tibet, leading to tremendous growth in architecture. Descriptions of buildings such as Managriha, Kailaskut Bhawan, and Bhadradiwas Bhawan have been found in the surviving journals of travellers and monks who lived during this era. For example, the famous 7th-century Chinese traveller Xuanzang described Kailaskut Bhawan, the palace of the Licchavi king Amshuverma.[20] The trade route also led to cultural exchange as well. The artistry of the Newar people—the indigenous inhabitants of the Kathmandu Valley—became highly sought after during this era, both within the Valley and throughout the greater Himalayas. Newar artists travelled extensively throughout Asia, creating religious art for their neighbours. For example, Araniko led a group of his compatriot artists through Tibet and China. Bhrikuti, the princess of Nepal who married Tibetan monarch Songtsän Gampo, was instrumental in introducing Buddhism to Tibet.

Malla era
The Licchavi era was followed by the Malla era. Rulers from Tirhut, upon being attacked by Muslims, fled north to the Kathmandu valley. They intermarried with Nepali royalty, and this led to the Malla era. The early years of the Malla era were turbulent, with raids and attacks from Khas and Turk Muslims. There was also a devastating earthquake which claimed the lives of a third of Kathmandu's population, including the king Abhaya Malla. These disasters led to the destruction of most of the architecture of the Licchavi era (such as Mangriha and Kailashkut Bhawan), and the loss of literature collected in various monasteries within the city. Despite the initial hardships, Kathmandu rose to prominence again and, during most of the Malla era, dominated the trade between India and Tibet. Nepali currency became the standard currency in trans-Himalayan trade.
During the later part of the Malla era, Kathmandu Valley comprised four fortified cities: Kantipur, Lalitpur, Bhaktapur, and Kirtipur. These served as the capitals of the Malla confederation of Nepal. These states competed with each other in the arts, architecture, esthetics, and trade, resulting in tremendous development. The kings of this period directly influenced or involved themselves in the construction of public buildings, squares, and temples, as well as the development of waterspouts, the institutionalisation of trusts (called guthis), the codification of laws, the writing of dramas, and the performance of plays in city squares. Evidence of an influx of ideas from India, Tibet, China, Persia, and Europe among other places can be found in a stone inscription from the time of king Pratap Malla. Books have been found from this era that describe their tantric tradition (e.g. Tantrakhyan), medicine (e.g. Haramekhala), religion (e.g. Mooldevshashidev), law, morals, and history. Amarkosh, a Sanskrit-Nepal Bhasa dictionary from 1381 AD, was also found. Architecturally notable buildings from this era include Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, the former durbar of Kirtipur, Nyatapola, Kumbheshwar, the Krishna temple, and others.
Medieval era
The Gorkha Kingdom ended the Malla confederation after the Battle of Kathmandu in 1768. This marked the beginning of the modern era in Kathmandu. The Battle of Kirtipur was the start of the Gorkha conquest of the Kathmandu Valley. Kathmandu was adopted as the capital of the Gorkha empire, and the empire itself was dubbed Nepal. During the early part of this era, Kathmandu maintained its distinctive culture. Buildings with characteristic Nepali architecture, such as the nine-story tower of Basantapur, were built during this era. However, trade declined because of continual war with neighbouring nations. Bhimsen Thapa supported France against Great Britain; this led to the development of modern military structures, such as modern barracks in Kathmandu. The nine-storey tower Dharahara was originally built during this era.
Rana rule
Rana rule over Nepal started with the Kot Massacre of 1846, which occurred near Hanuman Dhoka Durbar. During this massacre, most of Nepal's high-ranking officials were massacred by Jung Bahadur Rana and his supporters. Another massacre, the Bhandarkhal Massacre, was also conducted by Kunwar and his supporters in Kathmandu. During the Rana regime, Kathmandu's alliance shifted from anti-British to pro-British; this led to the construction of the first buildings in the style of Western European architecture. The most well-known of these buildings include Singha Durbar, Garden of Dreams, Shital Niwas, and the old Narayanhiti palace. The first modern commercial road in the Kathmandu Valley, the New Road, was also built during this era. Trichandra College (the first college of Nepal), Durbar High School (the first modern school of Nepal), and Bir Hospital (the first hospital of Nepal) were built in Kathmandu during this era. Education was only accessible to the privileged class. Rana rule was marked by despotism, economic exploitation and religious persecution.
Geography
Kathmandu is in the northwestern part of the Kathmandu Valley to the north of the Bagmati river and covers an area of 50.7 km2 (19.6 sq mi). The average elevation is 1,400 metres (4,600 ft) above sea level.[23] The city is bounded by several other municipalities of the Kathmandu valley: south of the Bagmati by Lalitpur Metropolitan City (Patan), with which it forms one urban area surrounded by a ring road, to the southwest by Kirtipur and to the east by Madyapur Thimi. To the north the urban area extends into several municipalities; Nagarjun, Tarakeshwor, Tokha, Budhanilkantha, Gokarneshwor and Kageshwori Manohara. However, the urban agglomeration extends well beyond the neighbouring municipalities, e.g. to Bhaktapur, and nearly covers the entire Kathmandu valley.
Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumante Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,500–3,000 metres (4,900–9,800 ft), and have passes which provide access to and from Kathmandu and its valley.[24][25][26] An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.
The city of Kathmandu and the surrounding valley are in the Deciduous Monsoon Forest Zone (altitude range of 1,200–2,100 metres (3,900–6,900 ft)), one of five vegetation zones defined for Nepal. The dominant tree species in this zone are oak, elm, beech, maple and others, with coniferous trees at higher altitude.[27]

Kathmandu administration
Kathmandu and adjacent cities are composed of neighbourhoods, which are utilized quite extensively and more familiar among locals. However, administratively the city is divided into 32 wards, numbered from 1 to 32. Earlier, there were 35 wards which made it the metropolitan city with the largest number of the wards.[28]
Kathmandu agglomeration
There is no officially defined agglomeration of Kathmandu. The urban area of the Kathmandu valley is split among three different districts (second level of administrative divisions within a province), which extend very little beyond the valley fringe, except towards the southern ranges, which have a comparatively small population.[29] They have the three highest population densities in the country. These 3 districts are administered by 21 local level bodies; 2 metropolitan cities (Kathmandu and Lalitpur), 16 municipalities and 3 rural municipalities. Imperial conversion
Five major climatic regions are found in Nepal. Of these, Kathmandu Valley is in the Warm Temperate Zone (elevation ranging from 1,200 to 2,300 metres (3,900 to 7,500 ft)), where the climate is fairly temperate, atypical for the region. This zone is followed by the Cool Temperate Zone with elevation varying between 2,100 and 3,300 metres (6,900 and 10,800 ft). Under Köppen's climate classification, portions of the city with lower elevations have a humid subtropical climate (Cwa), while portions of the city with higher elevations generally have a subtropical highland climate (Cwb). In the Kathmandu Valley, which is representative of its valley's climate, the average summer temperature varies from 28 to 30 °C (82 to 86 °F). The average winter temperature is 10.1 °C (50.2 °F).
The city generally has a climate with warm days followed by cool nights and mornings. Unpredictable weather is expected, given that temperatures can drop to 1 °C (34 °F) or less during the winter. During a 2013 cold front, the winter temperatures of Kathmandu dropped to −4 °C (25 °F), and the lowest temperature was recorded on 10 January 2013, at −9.2 °C (15.4 °F). Rainfall is mostly monsoon-based (about 65% of the total concentrated during the monsoon months of June to September), and decreases substantially (100 to 200 cm (39 to 79 in)) from eastern Nepal to western Nepal. Rainfall has been recorded at about 1,400 millimetres (55.1 in) for the Kathmandu valley, and averages 1,407 millimetres (55.4 in) for the city of Kathmandu. On average humidity is 75%.[24][30][31] The chart below is based on data from the Nepal Bureau of Standards & Meteorology, Weather Meteorology for 2005. The chart provides minimum and maximum temperatures during each month. The annual amount of precipitation was 1,124 millimetres (44.3 in) for 2005, as per monthly data included in the table above.[31] The decade of 2000–2010 saw highly variable and unprecedented precipitation anomalies in Kathmandu. This was mostly due to the annual variation of the southwest monsoon.[citation needed] For example, 2001 recorded only 356 mm (14 in) of precipitation due to an extraordinarily weak monsoon season. In contrast, 2003 was the wettest year ever in Kathmandu, totaling over 2,900 mm (114 in) of precipitation due to an exceptionally strong monsoon season.
Air quality
Air pollution is a major issue in the Kathmandu Valley.[36][37][38] According to the 2016 World Health Organization's Ambient Air Pollution Database,[39] the annual average PM2.5 (particulate matter) concentration in 2013 was 49 μg/m3, which is 4.9 times higher than recommended by the World Health Organization.[40][41] Starting in early 2017, the Government of Nepal and the Embassy of the United States in Kathmandu have monitored and publicly share real-time air quality data. In Nepal and Kathmandu, the annual premature deaths due to air pollution reached 37,399 and 9,943 respectively, according to a Republica news report published on 23 November, 2019. This indicates, around a quarter of the total deaths due to air pollution in Nepal are in Kathmandu.
Government and public services
Kathmandu Municipal Corporation (KMC) is the chief nodal agency for the administration of Kathmandu. The Municipality of Kathmandu was upgraded to a metropolitan city in 1995.
Metropolitan Kathmandu is divided into five sectors: the Central Sector, the East Sector, the North Sector, the City Core and the West Sector. For civic administration, the city is further divided into 35 administrative wards. The Council administers the Metropolitan area of Kathmandu city through its 177 elected representatives and 20 nominated members. It holds biannual meetings to review, process and approve the annual budget and make major policy decisions.[24][44] The ward's profile documents for the 35 wards prepared by the Kathmandu Metropolitan Council is detailed and provides information for each ward on population, the structure and condition of houses, the type of roads, educational, health and financial institutions, entertainment facilities, parking space, security provisions, etc. It also includes lists of development projects completed, on-going and planned, along with informative data about the cultural heritage, festivals, historical sites and the local inhabitants. Ward 16 is the largest, with an area of 437.4 ha; ward 26 is the smallest, with an area of 4 ha.[45]
Kathmandu is the headquarters of the surrounding Kathmandu district. The city of Kathmandu forms this district along with 10 other municipalities, namely Budanilkantha, Chandragiri, Dakshinkali, Gokarneshwar, Kageshwari Manohara, Kirtipur, Nagarjun, Shankharapur, Tarakeshwar and Tokha.
Law and order
The Metropolitan Police is the main law enforcement agency in the city. It is headed by a commissioner of police. The Metropolitan Police is a division of the Nepal Police, and the administrative control lies with the Ministry of Home Affairs.

Fire service
The fire service, known as the Barun Yantra Karyalaya (Nepali: वारुण यन्त्र कार्यालय), opened its first station in Kathmandu in 1937 with a single-vehicle.[46] An iron tower was erected to monitor the city and watch for a fire. As a precautionary measure, firemen were sent to the areas which were designated as accident-prone areas.[46] In 1944, the fire service was extended to the neighbouring cities of Lalitpur and Bhaktapur. In 1966, a fire service was established in Kathmandu central airport.[46] In 1975, a West German government donation added seven fire engines to Kathmandu's fire service.[46] The fire service in the city is also overlooked by an international non-governmental organization, the Firefighters Volunteer Association of Nepal (FAN), which was established in 2000 with the purpose of raising public awareness about fire and improving safety.[46]
Electricity and water supply
Public baths, Kathmandu. 1979
Electricity in Kathmandu is regulated and distributed by the Nepal Electricity Authority (NEA). Water supply and sanitation facilities are provided by the Kathmandu Upatyaka Khanepani Limited (KUKL). There is a severe shortage of water for household purposes such as drinking, bathing, cooking and washing and irrigation. People have been using bottled mineral water, water from tank trucks and from the ancient dhunge dharas (Nepali: ढुङ्गे धारा) for all the purposes related to water. The city water shortage should be solved by the completion of the much plagued Melamchi Water Supply Project by the end of 2019.[47][48]
Waste management
Waste management may be through composting in municipal waste management units, and at houses with home composting units. Both systems are common and established in India and neighbouring countries.[49]
Demographics
Kathmandu's urban cosmopolitan character has made it the most populous city in Nepal, recording a population of 671,846 residents living in 235,387 households in the metropolitan area, according to the 2001 census.[50] According to the National Population Census of 2011, the total population of Kathmandu city was 975,543 with an annual growth rate of 6.12% with respect to the population figure of 2001. 70% of the total population residing in Kathmandu are aged between 15 and 59.
Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of 5,076.6 hectares (12,545 acres) has expanded to 8,214 hectares (20,300 acres) in 2001. With this new area, the population density which was 85 in 1991 remained 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.[51]
Currently based on various data Kathmandu population is 1,442,300 with population density of 29,166.835 per sq.km making it as 6th densely populated city in the world.
Ethnic groups
The largest ethnic groups residing in Kathmandu Metropolitan City consists of primarily various caste groups of the Newar community at 25%, Hill Janajati/Adivisis like Tamang, Kirat, Gurung, Magar, Sherpa, etc. making~20%, Khas Brahmin at 24%, Khas Chhetri at 20%, and 7% Terai groups including Madhesi castes and Terai Janajatis/Adivasis like Tharus.[52] More recently, other hill ethnic groups and caste groups from Terai have come to represent a substantial proportion of the city's population. The major languages are Nepali and Nepal Bhasa, while English is understood by many, particularly in the service industry. According to data from 2011, the major religions in Kathmandu city are Hinduism 81.3%, Buddhism 9%, Islam 4.4% and other 5.2%.[53]
The linguistic profile of Kathmandu underwent drastic changes during the Shah dynasty's rule because of its strong bias towards the Hindu culture. Sanskrit language therefore was preferred and people were encouraged to learn it even by attending Sanskrit learning centres in Terai. Sanskrit schools were specially set up in Kathmandu and in the Terai region to inculcate traditional Hindu culture and practices originated from Nepal.[54]
Architecture and cityscape
The ancient trade route between India and Tibet that passed through Kathmandu enabled a fusion of artistic and architectural traditions from other cultures to be amalgamated with local art and architecture.[56] The monuments of Kathmandu City have been influenced over the centuries by Hindu and Buddhist religious practices. The architectural treasure of the Kathmandu valley has been categorized under the well-known seven groups of heritage monuments and buildings. In 2006 UNESCO declared these seven groups of monuments as a World Heritage Site (WHS). The seven monuments zones cover an area of 189 hectares (470 acres), with the buffer zone extending to 2,394 hectares (5,920 acres). The Seven Monument Zones inscribed originally in 1979 and with a minor modification in 2006 are the Durbar squares of Hanuman Dhoka, Patan and Bhaktapur, the Hindu temples of Pashupatinath and Changunarayan, the Buddhist stupas of Swayambhunath and Boudhanath.[57][58]
Durbar Squares
Main articles: Kathmandu Durbar Square and Hanuman Dhoka
The literal meaning of Durbar Square is a "place of palaces." There are three preserved Durbar Squares in Kathmandu valley and one unpreserved in Kirtipur. The Durbar Square of Kathmandu is in the old city and has heritage buildings representing four kingdoms (Kantipur, Lalitpur, Bhaktapur, Kirtipur); the earliest being the Licchavi dynasty. The complex has 50 temples and is distributed in two quadrangles of the Durbar Square. The outer quadrangle has the Kasthamandap, Kumari Ghar, and Shiva-Parvati Temple; the inner quadrangle has the Hanuman Dhoka palace. The squares were severely damaged in the April 2015 earthquake.
Hanuman Dhoka is a complex of structures with the royal palace of the Malla kings and of the Shah dynasty. It is spread over five acres. The eastern wing, with ten courtyards, is the oldest part, dating to the mid-16th century. It was expanded by King Pratap Malla in the 17th century with many temples. The royal family lived in this palace until 1886 when they moved to Narayanhiti Palace. The stone inscription outside is in fifteen languages.
Kumari Ghar is a palace in the centre of the Kathmandu city, next to the Durbar square where a royal Kumari selected from several Kumaris resides. Kumari, or Kumari Devi, is the tradition of worshipping young pre-pubescent girls as manifestations of the divine female energy or devi in South Asian countries. In Nepal the selection process is very rigorous. Previously, during the time of the monarchy, the queen and the priests used to appoint the proposed Kumari with delicate process of astrological examination and physical examination of 32 'gunas'. The china (Nepali: चिना), an ancient Hindu astrological report, of the Kumari and the reigning king, was ought to be similar. The Kumari is believed to be a bodily incarnation of the goddess Taleju (the Nepali name for Durga) until she menstruates, after which it is believed that the goddess vacates her body. Serious illness or a major loss of blood from an injury also causes her to revert to common status. The current Kumari, Trishna Shakya, age three at the time of appointment, was installed in September 2017 succeeding Matina Shakya who was the first Kumari of Kathmandu after the end of the monarchy.[59]
Kasthamandap is a three-storeyed temple enshrining an image of Gorakhnath. It was built in the 16th century in pagoda style. The name of Kathmandu is a derivative of the word Kasthamandap. It was built under the reign of King Laxmi Narsingha Malla. Kasthamandap stands at the intersection of two ancient trade routes linking India and Tibet at Maru square. It was originally built as a rest house for travellers.
Pashupatinath temple

Pashupatinath as seen from the banks of the Bagmati river
The Pashupatinath Temple (Nepali: पशुपतिनाथ मन्दिर) is a famous 5th century Hindu temple dedicated to Lord Shiva. Located on the banks of the Bagmati river, the Pashupatinath Temple is the oldest Hindu temple in Kathmandu.[60] It served as the seat of national deity, Lord Pashupatinath, until Nepal was secularized. However, a significant part of the temple was destroyed by Mughal invaders in the 14th century and little or nothing remains of the original 5th-century temple exterior. The temple as it stands today was built in the 19th century, although the image of the bull and the black four-headed image of Pashupati are at least 300 years old.[61] The temple is a UNESCO World Heritage Site.[61][62] Shivaratri, or the night of Lord Shiva, is the most important festival that takes place here, attracting thousands of devotees and sadhus.[citation needed]
Believers in Pashupatinath (mainly Hindus) are allowed to enter the temple premises, but non-Hindu visitors are allowed to view the temple only from the across the Bagmati River.[61] The priests who perform the services at this temple have been Brahmins from Karnataka in southern India since the time of Malla king Yaksha Malla.[63] This tradition is believed to have been started at the request of Adi Shankaracharya who sought to unify the states of Bharatam, a region in south Asia believed to be ruled by a mythological king Bharat, by encouraging cultural exchange. This procedure is followed in other temples around India, which were sanctified by Adi Shankaracharya.
The temple is built in the pagoda style of architecture, with cubic constructions and carved wooden rafters (tundal) on which they rest, and two-level roofs made of copper and gold.
Boudhanath
Boudhanath (Nepali: बौद्ध स्तुप; also written as Bouddhanath, Bodhnath, Baudhanath or the Khāsa Chaitya), is one of the holiest Buddhist sites in Nepal, along with the Swayambhunath. It is a very popular tourist site. Boudhanath is known as Khāsti by Newars and as Bauddha or Bodhnāth by speakers of Nepali.[64] About 11 km (7 mi) from the centre and northeastern outskirts of Kathmandu, the stupa's massive mandala makes it one of the largest spherical stupas in Nepal.[65] Boudhanath became a UNESCO World Heritage Site in 1979.
The base of the stupa has 108 small depictions of the Dhyani Buddha Amitabha. It is surrounded with a brick wall with 147 niches, each with four or five prayer wheels engraved with the mantra, om mani padme hum.[66] At the northern entrance where visitors must pass is a shrine dedicated to Ajima, the goddess of smallpox.[66] Every year the stupa attracts many Tibetan Buddhist pilgrims who perform full body prostrations in the inner lower enclosure, walk around the stupa with prayer wheels, chant, and pray.[66] Thousands of prayer flags are hoisted up from the top of the stupa downwards and dot the perimeter of the complex. The influx of many Tibetan refugees from China has seen the construction of over 50 Tibetan gompas (monasteries) around Boudhanath.
Swayambhu
Main article: Swayambhunath
Swayambhunath (Nepali: स्वयम्भू स्तूप) is a Buddhist stupa atop a hillock at the northwestern part of the city. This is among the oldest religious sites in Nepal. Although the site is considered Buddhist, it is revered by both Buddhists and Hindus. The stupa consists of a dome at the base; above the dome, there is a cubic structure with the eyes of Buddha looking in all four directions.[clarification needed] There are pentagonal toran above each of the four sides, with statues engraved on them. Behind and above the torana there are thirteen tiers. Above all the tiers, there is a small space above which lies a gajur.
Rani Pokhari
Main article: Ranipokhari
Ranipokhari (Nepali: रानी पोखरी, lit. 'Queen's Pond') is a historic artificial pond nestled in the heart of Kathmandu. It was built by king Pratap Malla in 1670 AD for his beloved queen after she lost her son and could not recover from her loss.[67] A large stone statue of an elephant in the south signifies the image of Pratap Malla and his two sons. Balgopaleshwor Temple stands still inside the temple above the pond. Rani Pokhari is opened once a year during the final day of Tihar i.e. Bhai Tika and Chhath festival. The world's largest Chhath takes place every year in Ranipokhari. The pond is one of Kathmandu's most famous landmarks and is known for its religious and aesthetic significance.

Arts
Stone carvings, called Chaityas, seen in street corners and courtyards
Kathmandu valley is described as "an enormous treasure house of art and sculptures", which are made of wood, stone, metal, and terracotta, and found in profusion in temples, shrines, stupas, gompas, chaityasm and palaces. The art objects are also seen in street corners, lanes, private courtyards and in open ground. Most art is in the form of icons of gods and goddesses. Kathmandu valley has had this art treasure for a very long time, but received worldwide recognition only after the country opened to the outside world in 1950.[54]
The religious art of Nepal and Kathmandu in particular consists of an iconic symbolism of the Mother Goddesses such as: Bhavani, Durga, Gaja-Lakshmi, Hariti-Sitala, Mahsishamardini, Saptamatrika (seven mother goddesses), and Sri-Lakshmi (wealth-goddess). From the 3rd century BCE, apart from the Hindu gods and goddesses, Buddhist monuments from the Ashokan period (it is said that Ashoka visited Nepal in 250 BC) have embellished Nepal in general and the valley in particular. These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.[68]
A broad typology has been ascribed to the decorative designs and carvings created by the people of Nepal. These artists have maintained a blend of Hinduism and Buddhism. The typology, based on the type of material used are: stone art, metal art, wood art, terracotta art, and painting.[69]
Museums
Kathmandu is home to a number of museums and art galleries, including the National Museum of Nepal and the Natural History Museum of Nepal. Nepal's art and architecture is an amalgamation of two ancient religions, Hinduism and Buddhism. These are amply reflected in the many temples, shrines, stupas, monasteries, and palaces in the seven well-defined Monument Zones of the Kathmandu valley are part of a UNESCO World Heritage Site. This amalgamation is also reflected in the planning and exhibitions in museums and art galleries throughout Kathmandu and its sister cities of Patan and Bhaktapur. The museums display unique artefacts and paintings from the 5th century CE to the present day, including archaeological exportation.[70]
Museums and art galleries in Kathmandu include:[70]
The National Museum
The Natural History Museum
Hanuman Dhoka Palace Complex
The Kaiser Library
The National Art Gallery
The NEF-ART (Nepal Fine Art) Gallery
The Nepal Art Council Gallery
Narayanhiti Palace Museum
The Taragaon Museum
National Museum of Nepal
The National Museum is in the western part of Kathmandu, near the Swayambhunath stupa in a historical building constructed in the early 19th century by General Bhimsen Thapa. It is the most important museum in the country, housing an extensive collection of weapons, art and antiquities of historic and cultural importance. The museum was established in 1928 as a collection house of war trophies and weapons, and the initial name of this museum was Chhauni Silkhana, meaning "the stone house of arms and ammunition". Given its focus, the museum contains many weapons, including locally made firearms used in wars, leather cannons from the 18th–19th century, and medieval and modern works in wood, bronze, stone and paintings.[71]
The Natural History Museum is in the southern foothills of Swayambhunath hill and has a sizeable collection of different species of animals, butterflies, and plants. The museum is noted for its display of species, from prehistoric shells to stuffed animals.[71]
The Tribhuvan Museum contains artifacts related to King Tribhuvan (1906–1955). It has a variety of pieces including his personal belongings, letters, and papers, memorabilia related to events he was involved in and a rare collection of photos and paintings of Royal family members. The Mahendra Museum is dedicated to the King Mahendra (1920–1972). Like the Tribhuvan Museum, it includes his personal belongings such as decorations, stamps, coins and personal notes and manuscripts, but it also has structural reconstructions of his cabinet room and office chamber. The Hanumandhoka Palace, a lavish medieval palace complex in the Durbar, contains three separate museums of historic importance. These museums include the Birendra museum, which contains items related to the second-last monarch, King Birendra.[71]
The enclosed compound of the Narayanhiti Palace Museum is in the north-central part of Kathmandu. "Narayanhiti" (Nepali: नारायणहिटी) comes from Narayana (Nepali: नारायण), a form of the Hindu god Lord Vishnu, and Hiti (Nepali: हिटी), meaning "water spout" (the temple of lord Vishnu is opposite to the palace, and the water spout is east of the main entrance to the precinct). The current palace building was built in 1970 in front of the old palace, built in 1915, in the form of a contemporary pagoda. It was built on the occasion of the marriage of the then crown prince and heir apparent to the throne, Birendra. The southern gate of the palace is at the crossing of Prithvipath and Durbar Marg roads. The palace area covers 30 hectares (74 acres) and is fully secured with gates on all sides.[72][73][74] This palace was the scene of the Nepali royal massacre. After the fall of the monarchy, it has been converted into a museum.
The Taragaon Museum presents the modern history of the Kathmandu valley.[75] It seeks to document 50 years of research and cultural heritage conservation of the Kathmandu Valley, documenting what artists, photographers, architects, and anthropologists from abroad had contributed in the second half of the 20th century. The actual structure of the museum showcases restoration and rehabilitation efforts to preserve the built heritage of Kathmandu. It was designed by Carl Pruscha (master-planner of the Kathmandu Valley)[76] in 1970 and constructed in 1971.[77] Restoration works began in 2010 to rehabilitate the Taragaon hostel into the Taragaon Museum. The design uses local brick along with modern architectural design elements, as well as the use of circle, triangles and squares.[76] The museum is within a short walk from the Boudhanath stupa, which itself can be seen from the museum tower.
Art galleries
A Buddhist statue display in Kathmandu
Kathmandu is a centre for art in Nepal, displaying the work of contemporary artists in the country and also collections of historical artists. Patan in particular is an ancient city noted for its fine arts and crafts. Art in Kathmandu is vibrant, demonstrating a fusion of traditionalism and modern art, derived from a great number of national, Asian, and global influences. Nepali art is commonly divided into two areas: the idealistic traditional painting known as Paubhas in Nepal and perhaps more commonly known as Thangkas in Tibet, closely linked to the country's religious history and on the other hand the contemporary western-style painting, including nature-based compositions or abstract artwork based on Tantric elements and social themes of which painters in Nepal are well noted for.[71] Internationally, the British-based charity, the Kathmandu Contemporary Art Centre is involved with promoting arts in Kathmandu.[78]
Kathmandu houses many notable art galleries. The NAFA Gallery, operated by the Arts and crafts Department of the Nepal Academy is housed in Sita Bhavan, a neo-classical old Rana palace.[71]
The Srijana Contemporary Art Gallery, inside the Bhrikutimandap Exhibition grounds, hosts the work of contemporary painters and sculptors, and regularly organizes exhibitions. It also runs morning and evening classes in the schools of art. Also of note is the Moti Azima Gallery, in a three-storied building in Bhimsenthan which contains an impressive collection of traditional utensils and handmade dolls and items typical of a medieval Newar house, giving an important insight into Nepali history. The J Art Gallery near the former royal palace in Durbarmarg displays the artwork of eminent, established Nepali painters. The Nepal Art Council Gallery, in the Babar Mahal, on the way to Tribhuvan International Airport contains artwork of both national and international artists and extensive halls regularly used for art exhibitions.[71]
Literature
The National Library of Nepal is located in Patan. It is the largest library in the country with more than 70,000 books in English, Nepali, Sanskrit, Hindi, and Nepal Bhasa. The library is in possession of rare scholarly books in Sanskrit and English dating from the 17th century AD. Kathmandu also contains the Kaiser Library, in the Kaiser Mahal on the ground floor of the Ministry of Education building. This collection of around 45,000 books is derived from a personal collection of Kaiser Shamsher Jang Bahadur Rana. It covers a wide range of subjects including history, law, art, religion, and philosophy, as well as a Sanskrit manual of Tantra, which is believed to be over 1,000 years old.[71] The 2015 earthquake caused severe damage to the Ministry of Education building, and the contents of the Kaiser Library have been temporarily relocated.
Asa Archives
The Asa Archives are also noteworthy. They specialize in medieval history and religious traditions of the Kathmandu valley. The archives, in Kulambhulu, have a collection of some 6,000 loose-leaf handwritten books and 1,000 palm-leaf manuscripts (mostly in Sanskrit or Nepal Bhasa) and a manuscript dated to 1464.[71]
Cinema and theatre
Kathmandu is home to Nepali cinema and theatres. The city contains several theatres, including the National Dance Theatre in Kanti Path, the Ganga Theatre, the Himalayan Theatre and the Aarohan Theater Group founded in 1982. The M. Art Theater is based in the city. The Gurukul School of Theatre organizes the Kathmandu International Theater Festival, attracting artists from all over the world.[79] A mini theatre has been opened at the Hanumandhoka Durbar Square, established by the Durbar Conservation and Promotion Committee.
Kathmandu has a number of cinemas (old single screen establishments and some new multiplexes) showing Nepali, Bollywood and Hollywood films. Some old establishments include Vishwajyoti Cinema Hall, Jai Nepal Hall, Kumari Cinema Hall, Gopi Krishna Cinema Hall and Guna Cinema Hall. Kathmandu also houses some international standard cinema theatres and multiplexes, such as QFX Cinemas, Cine De Chef, Fcube Cinemas, Q's Cinemas, Big Movies, BSR Movies and many more.
Music
Traditional Buddhist musical performance during Gunla
Kathmandu is the center of music and dance in Nepal, and these art forms are integral to understanding the city. Musical performances are organized in cultural venues. Music is a part of the traditional aspect of Kathmandu. Gunla is the traditional music festival according to Nepal Sambat. Newar music originated in Kathmandu. Furthermore, music from all over Nepal can be found in Kathmandu.
A number of hippies visited Kathmandu during the 1970s and introduced rock and roll, rock, and jazz to the city. Kathmandu is noted internationally for its jazz festival, popularly known as Jazzmandu. It is the only jazz festival in the Himalayan region and was established in March 2002. The festival attracts musicians from countries worldwide, such as Australia, Denmark, United States, Benin, and India.[80]
The city has been referenced in numerous songs, including works by Cat Stevens ('Katmandu', Mona Bone Jakon (1970)), Bob Seger ('Katmandu', Beautiful Loser (1975)), Rush ('A Passage to Bangkok', Pulling into Kathmandu; 2112, 1976), Krematorij ('Kathmandu', Three Springs (2000)), Fito Páez (Tráfico por Katmandú – "Traffic through Kathmandu") and Cavalcade ('Kathmandu Kid') 2019.
Cuisine
One of the typical Nepali meals Dal bhat in Kathmandu
The staple food of most people in Kathmandu is dal bhat. This consists of rice and lentil soup, generally served with vegetable curries, achar and sometimes Chutney. Momo, a type of Nepali version of Tibetan dumpling, has become prominent in Nepal with many street vendors and restaurants selling it. It is one of the most popular fast foods in Kathmandu. Various Nepali variants of momo including buff (i.e. buffalo) momo, chicken momo, and vegetarian momo are famous in Kathmandu.
Most of the cuisines found in Kathmandu are non-vegetarian. However, the practice of vegetarianism is not uncommon, and vegetarian cuisines can be found throughout the city. Consumption of beef is very uncommon and considered taboo in many places. Buff (meat of water buffalo) is very common. There is a strong tradition of buff consumption in Kathmandu, especially among Newars, which is not found in other parts of Nepal. Consumption of pork was considered taboo until a few decades ago. Due to the intermixing with Kirat cuisine from eastern Nepal, pork has found a place in Kathmandu dishes. A fringe population of devout Hindus and Muslims consider it taboo. The Muslims forbid eating buff as from Quran while Hindus eat all varieties except beef as they consider cow to be a goddess and symbol of purity. The chief lunch/snack for locals and visitors is mostly Momo or Chowmein.
Kathmandu had only one western-style restaurant in 1955.[81] A large number of restaurants in Kathmandu have since opened, catering Nepali cuisine, Tibetan cuisine, Chinese cuisine and Indian cuisine in particular. Many other restaurants have opened to accommodate locals, expatriates, and tourists. The growth of tourism in Kathmandu has led to culinary creativity and the development of hybrid foods to accommodate for tourists such as American chop suey, which is a sweet-and-sour sauce with crispy noodles with a fried egg commonly added on top and other westernized adaptations of traditional cuisine.[81] Continental cuisine can be found in selected places. International chain restaurants are rare, but some outlets of Pizza Hut and KFC have recently opened there. It also has several outlets of the international ice-cream chain Baskin-Robbins.[82]
Kathmandu has a larger proportion of tea drinkers than coffee drinkers. Tea is widely served but is extremely weak by western standards. It is richer and contains tea leaves boiled with milk, sugar, and spices. Alcohol is widely drunk, and there are numerous local variants of alcoholic beverages. Drinking and driving is illegal, and authorities have a zero-tolerance policy.[83] Ailaa and thwon (alcohol made from rice) are the alcoholic beverages of Kathmandu, found in all the local bhattis (alcohol serving eateries). Chhyaang, tongba (fermented millet or barley) and raksi are alcoholic beverages from other parts of Nepal which are found in Kathmandu. However, shops and bars in Kathmandu widely sell western and Nepali beers.

Festivals
Samyak, a Buddhist festival during which statues of Buddhas from the ancient monasteries are displayed together. Note the statue of Hanuman next to the Buddhas in the picture, a common example of religious harmony in Kathmandu.
Most of the fairs and festivals in Kathmandu originated in the Malla period or earlier. Traditionally, these festivals were celebrated by Newars. In recent years, these festivals have found wider participation from other Kathmanduites as well. As the capital of the Nepal, various national festivals are celebrated in Kathmandu. With mass migration to the city, the cultures of Khas from the west, Kirats from the east, Bon/Tibetan from the north, and Mithila from the south meet in the capital and mingle harmoniously. The festivities such as the Ghode (horse) Jatra, Indra Jatra, Dashain Durga Puja festivals, Shivratri and many more are observed by all Hindu and Buddhist communities of Kathmandu with devotional fervor and enthusiasm. Social regulation in the codes enacted incorporates Hindu traditions and ethics. These were followed by the Shah kings and previous kings, as devout Hindus and protectors of the Buddhist religion.

Cultural continuity has been maintained for centuries in the exclusive worship of goddesses and deities in Kathmandu and the rest of the country. These deities include the Ajima,[84] Taleju (or Tulja Bhavani or Taleju Bhawani)[85][86] and her other forms : Digu Taleju (or Degu Taleju)[87] and Kumari (the living goddess).[88] The artistic edifices have now become places of worship in the everyday life of the people, therefore a roster is maintained to observe annual festivals. There are 133 festivals held in the year.[89]
Some of the traditional festivals observed in Kathmandu, apart from those previously mentioned, are Bada Dashain, Tihar, Chhath, Maghe Sankranti, Nag Panchami, Janai Purnima, Pancha Dan, Teej/Rishi Panchami, Pahan Charhe, Jana Baha Dyah Jatra (White Machchhendranath Jatra), and Matatirtha Aunsi.[56]
Religions
Hinduism

Assumedly, together with the kingdom of Licchhavi (c. 400 to 750), Hinduism and the endogam social stratification of the caste was established in Kathmandu Valley. The Pashupatinath Temple, Changu Narayan Temple, and the Kasthamandap are of particular importance to Hindus. Other notable Hindu temples in Kathmandu and the surrounding valley include Bajrayogini Temple, Dakshinkali Temple, Guhyeshwari Temple, and the Shobha Bhagawati shrine.
The Bagmati river which flows through Kathmandu is considered a holy river both by Hindus and Buddhists, and many Hindu temples are on the banks of this river. The importance of the Bagmati also lies in the fact that Hindus are cremated on its banks, and Kirants are buried in the hills by its side. According to the Nepali Hindu tradition, the dead body must be dipped three times into the Bagmati before cremation. The chief mourner (usually the first son) who lights the funeral pyre must take a holy riverwater bath immediately after cremation. Many relatives who join the funeral procession also take bath in the Bagmati or sprinkle the holy water on their bodies at the end of cremation as the Bagmati is believed to purify people spiritually.
Buddhism
Buddhism was brought into Kathmandu with the arrival of Buddhist monks during the time of Buddha (c. 563 – 483 BCE[90]). They established a forest monastery in Sankhu. This monastery was renovated by Shakyas after they fled genocide from Virudhaka (r. 491–461 BCE).
During the Hindu Lichchavi era (c. 400 to 750), various monasteries and orders were created which successively led to the formation of Newar Buddhism, which is still practiced in the primary liturgical language of Hinduism, Sanskrit.
Legendary Princess Bhrikuti (7th-century) and artist Araniko (1245–1306 CE) from that tradition of Kathmandu valley played a significant role in spreading Buddhism in Tibet and China. There are over 108 traditional monasteries (Bahals and Baháʼís) in Kathmandu based on Newar Buddhism. Since the 1960s, the permanent Tibetan Buddhist population of Kathmandu has risen significantly so that there are now over fifty Tibetan Buddhist monasteries in the area. Also, with the modernization of Newar Buddhism, various Theravada Bihars have been established.
Islam
Jama Masjid, Ghantaghar
Muslims in Kathmandu pray to Allah on Friday (the day of Namaj) often going to the Jame Masjid in Ghantaghar, near Ratnapark.
Kirat Mundhum
Kirant Mundhum is one of the indigenous animistic practices of Nepal. It is practiced by the Kirat people. Some animistic aspects of Kirant beliefs, such as ancestor worship (worship of Ajima) are also found in Newars of Kirant origin. Ancient religious sites believed to be worshipped by ancient Kirats, such as Pashupatinath, Wanga Akash Bhairabh (Yalambar) and Ajima are now worshipped by people of all Dharmic religions in Kathmandu. Kirats who have migrated from other parts of Nepal to Kathmandu practice Mundhum in the city.[91]
Other religions
Sikhism is practiced primarily in Gurudwara at Kupundole. An earlier temple of Sikhism is also present in Kathmandu which is now defunct.
Jainism is practiced by a small community. A Jain temple is present in Gyaneshwar, where Jains practice their faith.
According to the records of the Spiritual Assembly of the Baháʼís of Nepal, there are approximately 300 followers of the Baháʼí Faith in Kathmandu valley. They have a national office in Shantinagar, Baneshwor. The Baháʼís also have classes for children at the National Centre and other localities in Kathmandu.
Islam is practiced in Kathmandu but Muslims are a minority, accounting for about 4.4% of the population of Nepal.[92]
It is said that in Kathmandu alone there are 170 Christian churches. Christian missionary hospitals, welfare organizations, and schools are also operating. Nepali citizens who served as soldiers in Indian and British armies, who had converted to Christianity while in service, on return to Nepal continue to practice their religion. They have contributed to the spread of Christianity and the building of churches in Nepal and in Kathmandu, in particular.[93][94]
Education
The oldest modern school in Nepal, the Durbar High School, and the oldest college, the Tri-Chandra College, are both in Kathmandu. The largest (according to number of students and colleges), the oldest and most distinguished university in Nepal the Tribhuvan University, located in Kirtipur. The second largest university, Kathmandu University (KU), is in Dhulikhel, Kavre on the outskirts of Kathmandu. It is the second oldest university in Nepal, established in November 1991.[95] Not surprisingly the best schools and colleges of Nepal are located in Kathmandu and its adjoining cities. Every year thousands of students from all over Nepal arrive at Kathmandu to get admission in the various schools and colleges. One of the key concerns of educationists and concerned citizens is the massive outflux of students from Nepal to outside Nepal for studies. Every year thousands of students apply for No Objection Certificates for studying abroad. Consultancy firms specializing in preparing students to go abroad can be found in all prominent locations. The reason for such an outflux range from perceived low quality of education, political instability, fewer opportunities in the job market, opportunities for earning while learning abroad and better job prospects with an international degree.
Healthcare
Healthcare in Kathmandu is the most developed in Nepal, and the city and surrounding valley is home to some of the best hospitals and clinics in the country. Bir Hospital is the oldest, established in July 1889 by Bir Shamsher Jang Bahadur Rana. Notable hospitals include Bir Hospital, Nepal Medical College and Teaching Hospital (Jorpati), Tribhuvan University Institute of Medicine (Teaching Hospital), Patan Hospital, Kathmandu Model Hospital, Scheer Memorial Hospital, Om Hospital, Norvic Hospital, Grande International Hospital, Nobel Hospital and many more.
The city is supported by specialist hospitals/clinics such as Shahid Shukraraj Tropical Hospital, Shahid Gangalal Foundation, Kathmandu Veterinary Hospital, Nepal Eye Hospital, Kanti Children's Hospital, Nepal International Clinic (Travel and Mountain Medicine Center), Neuro Center, Spinal Rehabilitation center and Bhaktapur Cancer Hospital. Most of the general hospitals are in the city center, although several clinics are elsewhere in Kathmandu district.
Tilganga Institute of Ophthalmology is an Ophthalmological hospital in Kathmandu. It pioneered the production of low cost intraocular lenses (IOLs), which are used in cataract surgery.[96] The team of Dr. Sanduk Ruit in Tilganga pioneered sutureless small-incision cataract surgery (SICS),[97][98] a technique which has been used to treat 4 million of the world's 20 million people with cataract blindness.
Medical colleges
Institute of Medicine, the central college of Tribhuvan University is the first medical college of Nepal and is in Maharajgunj, Kathmandu. It was established in 1972 and started to impart medical education from 1978. Other major institutions include Patan Academy of Health Sciences, Kathmandu Medical College, Nepal Medical College, KIST Medical College, Nepal Army Institute of Health Sciences, National Academy of Medical Sciences (NAMS) and Kathmandu University School of Medical Sciences (KUSMS), are also in or around Kathmandu.
Economy
The location and terrain of Kathmandu have played a significant role in the development of a stable economy which spans millennia. The city is in an ancient lake basin, with fertile soil and flat terrain. This geography helped form a society based on agriculture. This, combined with its location between India and China, helped establish Kathmandu as an important trading centre over the centuries. Kathmandu's trade is an ancient profession that flourished along an offshoot of the Silk Road which linked India and Tibet. From centuries past, Lhasa Newar merchants of Kathmandu have conducted trade across the Himalaya and contributed to spreading art styles and Buddhism across Central Asia.[100] Other traditional occupations are farming, metal casting, woodcarving, painting, weaving, and pottery.[101]
Kathmandu is the most important industrial and commercial centre in Nepal. The Nepal Stock Exchange, the head office of the national bank, the chamber of commerce, as well as head offices of national and international banks, telecommunication companies, the electricity authority, and various other national and international organizations are in Kathmandu. The major economic hubs are the New Road, Durbar Marg, Ason and Putalisadak.[101]
The economic output of the metropolitan area of around Rs. 550 billion approximately per year alone is worth more than one third of national GDP (nominal), while the per capita income of $2200 is approximately three times the national average.[102] Kathmandu exports handicrafts, artworks, garments, carpets, pashmina, paper; trade accounts for 21% of its revenues.[101][102] Manufacturing is also important and accounts for 19% of the revenue that Kathmandu generates. Garments and woolen carpets are the most notable manufactured products.[102] Other economic sectors in Kathmandu include agriculture (9%), education (6%), transport (6%), and hotels and restaurants (5%).[102] Kathmandu is famous for lokta paper and pashmina shawls.
Tourism
Tourism is considered another important industry in Nepal. This industry started around 1950, as the country's political makeup changed and ended the country's isolation from the rest of the world. In 1956, air transportation was established and the Tribhuvan Highway, between Kathmandu and Raxaul (at India's border), was started. Separate organizations were created in Kathmandu to promote this activity; some of these include the Tourism Development Board, the Department of Tourism and the Civil Aviation Department. Furthermore, Nepal became a member of several international tourist associations. Establishing diplomatic relations with other nations further accentuated this activity. The hotel industry, travel agencies, training of tourist guides, and targeted publicity campaigns are the chief reasons for the remarkable growth of this industry in Nepal, and in Kathmandu in particular.[103] Since then, tourism in Nepal has thrived. It is the country's most important industry.[104] Tourism is a major source of income for most of the people in the city, with several hundred thousand visitors annually. Hindu and Buddhist pilgrims from all over the world visit Kathmandu's religious sites such as Pashupatinath, Swayambhunath, Boudhanath, Changunarayan and Budhanilkantha. From a mere 6,179 tourists in 1961/62, the number increased to 491,504 in 1999/2000. In economic terms, the foreign exchange registered 3.8% of the GDP in 1995/96 but then started declining. Following the end of the Maoist insurgency, there was a significant rise in the number of tourist arrivals, with 509,956 tourists recorded in 2009. Since then, tourism has improved as the country transitioned into a republic. The high level of tourism is attributed to the natural grandeur of the Himalayas and the rich cultural heritage of the country.[103]
Hyatt Regency, Kathmandu
The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel that was coined to rhyme with Thamel.[105] Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveller's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Ason is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.
With the opening of the tourist industry after the change in the political scenario of Nepal in 1950, the hotel industry drastically improved.[106] Now Kathmandu boasts several luxuries such as the Hyatt Regency, Dwarika's, Hotel Yak & Yeti, The Everest Hotel, Hotel Radisson, Hotel De L'Annapurna, The Malla Hotel, Shangri-La Hotel (not operated by the Shangri-La Hotel Group) and Hotel Shanker. There are several four-star hotels such as Akama Hotel, Hotel Vaishali, Hotel Narayani, The Blue Star and Grand Hotel. The Garden Hotel, Hotel Ambassador, and Aloha Inn are among the three-star hotels in Kathmandu. Hotels like Hyatt Regency, De L'Annapurna, and Yak & Yeti are among the five-star hotels with casinos as well.
Transport
The total length of roads in Nepal is recorded to be 17,182 km (10,676 mi), as of 2003–04. This fairly large network has helped the economic development of the country, particularly in the fields of agriculture, horticulture, vegetable farming, industry and also tourism.[108] In view of the hilly terrain, transportation takes place in Kathmandu are mainly by road and air. Kathmandu is connected by the Tribhuvan Highway to the south connecting India, Prithvi Highway to the west and Araniko Highway to the north connecting China. The BP Highway connects Kathmandu to the eastern part of Nepal through Sindhuli.[109] The fast-track is under construction which will be the shortest route to connect Terai with the valley.
Sajha Yatayat provides regular bus services throughout Kathmandu and the surrounding valley. Other bus companies including micro-bus companies operate several unscheduled routes. Trolleybusses used to operate on the route between Tripureshwor and Suryabinayak on a 13-kilometer route.
Air
The main international airport serving Kathmandu valley is the Tribhuvan International Airport, about 6 kilometres (3.7 mi) from the city centre and is operated by the Civil Aviation Authority of Nepal.[111] It has two terminals, one domestic and one international. At present, it connects 30 cities around the globe in Europe, Asia and the Middle East such as Istanbul, Delhi, Mumbai, Bangalore, Kolkata, Singapore, Bangkok, Kuala Lumpur, Dhaka, Paro, Lhasa, Chengdu, Guangzhou and Hong Kong.[111] Since 2013, Turkish Airlines connects Istanbul to Kathmandu.[112] Oman Air also connects Muscat to Kathmandu since 2010.[113] Nepal Airlines started flying to Tokyo-Narita from March 2, 2020. Regionally, several Nepali airlines operate from the city, inc

Kathmandu (/ˌkætmænˈduː/;[3] Nepali: काठमाडौं, Nepali pronunciation: [kɑʈʰmɑɳɖu]) is the capital city of the Federal Democratic Republic of Nepal, the largest Himalayan state in Asia. It is the largest metropolis in Nepal, with a population of 1.4 million in the city proper, and 6 million in its urban agglomeration across the Kathmandu Valley, which includes the towns of Lalitpur, Kirtipur, Madhyapur Thimi and Bhaktapur. Kathmandu is also the largest metropolis in the Himalayan hill region.
The city stands at an elevation of approximately 1,400 metres (4,600 feet) above sea level in the bowl-shaped Kathmandu Valley of central Nepal. The valley is historically termed as "Nepal Proper" and has been the home of Newar culture, a cosmopolitan urban civilization in the Himalayan foothills. The city was the royal capital of the Kingdom of Nepal and hosts palaces, mansions and gardens of the Nepalese aristocracy. It has been home to the headquarters of the South Asian Association for Regional Cooperation (SAARC) since 1985. Today, it is the seat of government of the Nepalese republic established in 2008; and is part of the Bagmati Zone in Nepalese administrative geography.
Kathmandu has been the center of Nepal's history, art, culture and economy. It has a multiethnic population within a Hindu and Buddhist majority. Religious and cultural festivities form a major part of the lives of people residing in Kathmandu. Tourism is an important part of the economy as the city is the gateway to the Nepalese Himalayas. There are also seven casinos in the city. In 2013, Kathmandu was ranked third among the top ten upcoming travel destinations in the world by TripAdvisor, and ranked first in Asia. Historic areas of Kathmandu were devastated by a 7.8 magnitude earthquake on 25 April 2015. Nepali is the most spoken language in the city, while English is understood by the city's educated residents.
Etymology
The city of Kathmandu is named after Kasthamandap temple, which stood in Durbar Square. In Sanskrit, Kāṣṭha (काष्ठ) means "wood" and Maṇḍap (/मण्डप) means "covered shelter". This temple, also known as Maru Satta: in the Newar language, was built in 1596 by Biseth in the period of King Laxmi Narsingh Malla. The two-story structure was made entirely of wood and used no iron nails nor supports. According to legend, all the timber used to build the pagoda was obtained from a single tree.[4] The structure collapsed during a major earthquake on 25 April 2015.
The colophons of ancient manuscripts, dated as late as the 20th century, refer to Kathmandu as Kāṣṭhamaṇḍap Mahānagar in Nepal Mandala. Mahānagar means "great city". The city is called "Kāṣṭhamaṇḍap" in a vow that Buddhist priests still recite to this day. Thus, Kathmandu is also known as Kāṣṭhamaṇḍap. During medieval times, the city was sometimes called Kāntipur (कान्तिपुर). This name is derived from two Sanskrit words – Kānti and pur. "Kānti" is a word that stands for "beauty" and is mostly associated with light and "pur" means place. Thus, giving it a meaning as "City of light".
Among the indigenous Newar people, Kathmandu is known as Yeṃ Deśa (येँ देश), and Patan and Bhaktapur are known as Yala Deśa (यल देश) and Khwopa Deśa (ख्वप देश).[5] "Yen" is the shorter form of Yambu (यम्बु), which originally referred to the northern half of Kathmandu.[clarification needed][6]
History

Manjushree, with Chandrahrasa, the Buddhist deity said to have created the valley
Archaeological excavations in parts of Kathmandu have found evidence of ancient civilizations. The oldest of these findings is a statue, found in Maligaon, that was dated at 185 AD.[7] The excavation of Dhando Chaitya uncovered a brick with an inscription in Brahmi script. Archaeologists believe it is two thousand years old.[7] Stone inscriptions are a ubiquitous element at heritage sites and are key sources for the history of Nepal.
The earliest Western reference to Kathmandu appears in an account of Jesuit Fathers Johann Grueber and Albert d'Orville. In 1661, they passed through Nepal on their way from Tibet to India, and reported that they reached "Cadmendu", the capital of Nepal kingdom.[8]
Ancient history
The ancient history of Kathmandu is described in its traditional myths and legends. According to Swayambhu Purana, present-day Kathmandu was once a huge and deep lake named "Nagdaha", as it was full of snakes. The lake was cut drained by Bodhisatwa Manjusri with his sword, and the water was evacuated out from there. He then established a city called Manjupattan, and made Dharmakar the ruler of the valley land. After some time, a demon named Banasur closed the outlet, and the valley was again a lake. Then lord Krishna came to Nepal, killed Banasur, and again drained out the water. He brought some Gopals along with him and made Bhuktaman the king of Nepal.[9][10][11]
Kotirudra Samhita of Shiva Purana, Chapter 11, shloka 18 refers to the place as Nayapala city, which was famous for its Pashupati Shivalinga. The name Nepal probably originates from this city Nayapala.
Very few historical records exist of the period before the medieval Licchavis rulers. According to Gopalraj Vansawali, a genealogy of Nepali monarchy, the rulers of Kathmandu Valley before the Licchavis were Gopalas, Mahispalas, Aabhirs, Kirants, and Somavanshi.[11][12] The Kirata dynasty was established by Yalamber. During the Kirata era, a settlement called Yambu existed in the northern half of old Kathmandu. In some of the Sino-Tibetan languages, Kathmandu is still called Yambu. Another smaller settlement called Yengal was present in the southern half of old Kathmandu, near Manjupattan. During the reign of the seventh Kirata ruler, Jitedasti, Buddhist monks entered Kathmandu valley and established a forest monastery at Sankhu.
Licchavi era
The Licchavis from the Indo-Gangetic plain migrated north and defeated the Kiratas, establishing the Licchavi dynasty, circa 400 AD. During this era, following the genocide of Shakyas in Lumbini by Virudhaka, the survivors migrated north and entered the forest monastery in Sankhu masquerading as Koliyas. From Sankhu, they migrated to Yambu and Yengal (Lanjagwal and Manjupattan) and established the first permanent Buddhist monasteries of Kathmandu. This created the basis of Newar Buddhism, which is the only surviving Sanskrit-based Buddhist tradition in the world.[13] With their migration, Yambu was called Koligram and Yengal was called Dakshin Koligram[14] during most of the Licchavi era.[15]
Eventually, the Licchavi ruler Gunakamadeva merged Koligram and Dakshin Koligram, founding the city of Kathmandu.[15] The city was designed in the shape of Chandrahrasa, the sword of Manjushri. The city was surrounded by eight barracks guarded by Ajimas. One of these barracks is still in use at Bhadrakali (in front of Singha Durbar). The city served as an important transit point in the trade between India and Tibet, leading to tremendous growth in architecture. Descriptions of buildings such as Managriha, Kailaskut Bhawan, and Bhadradiwas Bhawan have been found in the surviving journals of travelers and monks who lived during this era. For example, the famous 7th-century Chinese traveler Xuanzang described Kailaskut Bhawan, the palace of the Licchavi king Amshuverma.[16] The trade route also led to cultural exchange as well. The artistry of the Newar people—the indigenous inhabitants of the Kathmandu Valley—became highly sought after during this era, both within the Valley and throughout the greater Himalayas. Newar artists traveled extensively throughout Asia, creating religious art for their neighbors. For example, Araniko led a group of his compatriot artists through Tibet and China. Bhrikuti, the princess of Nepal who married Tibetan monarch Songtsän Gampo, was instrumental in introducing Buddhism to Tibet.
Malla era
The Licchavi era was followed by the Malla era. Rulers from Tirhut, upon being attacked by Muslims, fled north to the Kathmandu valley. They intermarried with Nepali royalty, and this led to the Malla era. The early years of the Malla era were turbulent, with raids and attacks from Khas and Turk Muslims. There was also a devastating earthquake which claimed the lives of a third of Kathmandu's population, including the king Abhaya Malla. These disasters led to the destruction of most of the architecture of the Licchavi era (such as Mangriha and Kailashkut Bhawan), and the loss of literature collected in various monasteries within the city. Despite the initial hardships, Kathmandu rose to prominence again and, during most of the Malla era, dominated the trade between India and Tibet. Nepali currency became the standard currency in trans-Himalayan trade.
During the later part of the Malla era, Kathmandu Valley comprised four fortified cities: Kantipur, Lalitpur, Bhaktapur, and Kirtipur. These served as the capitals of the Malla confederation of Nepal. These states competed with each other in the arts, architecture, aesthetics, and trade, resulting in tremendous development. The kings of this period directly influenced or involved themselves in the construction of public buildings, squares, and temples, as well as the development of waterspouts, the institutionalization of trusts (called guthis), the codification of laws, the writing of dramas, and the performance of plays in city squares. Evidence of an influx of ideas from India, Tibet, China, Persia, and Europe among other places can be found in a stone inscription from the time of king Pratap Malla. Books have been found from this era that describe their tantric tradition (e.g. Tantrakhyan), medicine (e.g. Haramekhala), religion (e.g. Mooldevshashidev), law, morals, and history. Amarkosh, a Sanskrit-Nepal Bhasa dictionary from 1381 AD, was also found. Architecturally notable buildings from this era include Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, the former durbar of Kirtipur, Nyatapola, Kumbheshwar, the Krishna temple, and others.
Modern era
Early Shah rule
The Gorkha Kingdom ended the Malla confederation after the Battle of Kathmandu in 1768. This marked the beginning of the modern era in Kathmandu. The Battle of Kirtipur was the start of the Gorkha conquest of the Kathmandu Valley. Kathmandu was adopted as the capital of the Gorkha empire, and the empire itself was dubbed Nepal. During the early part of this era, Kathmandu maintained its distinctive culture. Buildings with characteristic Nepali architecture, such as the nine-story tower of Basantapur, were built during this era. However, trade declined because of continual war with neighboring nations. Bhimsen Thapa supported France against Great Britain; this led to the development of modern military structures, such as modern barracks in Kathmandu. The nine-storey tower Dharahara was originally built during this era.
Rana rule
Rana rule over Nepal started with the Kot Massacre, which occurred near Hanuman Dhoka Durbar. During this massacre, most of Nepal's high-ranking officials were massacred by Jang Bahadur Rana and his supporters. Another massacre, the Bhandarkhal Massacre, was also conducted by Kunwar and his supporters in Kathmandu. During the Rana regime, Kathmandu's alliance shifted from anti-British to pro-British; this led to the construction of the first buildings in the style of Western European architecture. The most well-known of these buildings include Singha Durbar, Garden of Dreams, Shital Niwas, and the old Narayanhiti palace.The first modern commercial road in the Kathmandu Valley, the New Road, was also built during this era. Trichandra College (the first college of Nepal), Durbar School (the first modern school of Nepal), and Bir Hospital (the first hospital of Nepal) were built in Kathmandu during this era. Rana rule was marked by despotism, economic exploitation and religious persecution.[17][18]
Geography
Kathmandu is in the northwestern part of the Kathmandu Valley to the north of the Bagmati River and covers an area of 50.7 km2 (19.6 sq mi). The average elevation is 1,400 metres (4,600 ft) above sea level.[19] The city is bounded by several other municipalities of the Kathmandu valley: south of the Bagmati by Lalitpur Sub-Metropolitan City (Patan), with which it forms one urban area surrounded by a ring road, to the southwest by Kirtipur Municipality and to the east by Madyapur Thimi Municipality. To the north the urban area extends into several Village Development Committees. However, the urban agglomeration extends well beyond the neighboring municipalities, e.g. to Bhaktapur, and nearly covers the entire Kathmandu valley.

Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumant Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,500–3,000 metres (4,900–9,800 ft), and have passes which provide access to and from Kathmandu and its valley.[20][21][22] An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.
Kathmandu and its valley are in the Deciduous Monsoon Forest Zone (altitude range of 1,200–2,100 metres (3,900–6,900 ft)), one of five vegetation zones defined for Nepal. The dominant tree species in this zone are oak, elm, beech, maple and others, with coniferous trees at higher altitude.[23]
Kathmandu administration
Kathmandu and adjacent cities are composed of neighborhoods, which are utilized quite extensively and more familiar among locals. However, administratively the city is divided into 35 wards, numbered from 1 to 35.[24]
Kathmandu agglomeration
There is no officially defined agglomeration of Kathmandu. The urban area of the Kathmandu valley is split among three different districts (collections of local government units within a zone) which extend very little beyond the valley fringe, except towards the southern ranges, which have comparatively small population. They have the three highest population densities in the country. Within these 3 districts lie VDCs (villages), 20 municipalities and 2 metropolitan municipality (maha-nagarpalika: Kathmandu and lalitpur). The following data table describes these districts which likely would be considered an agglomeration:
Administrative district (Nepali: जिल्ला; jillā) Area (km²)
Five major climatic regions are found in Nepal. Of these, Kathmandu Valley is in the Warm Temperate Zone (elevation ranging from 1,200 to 2,300 metres (3,900 to 7,500 ft)), where the climate is fairly temperate, atypical for the region. This zone is followed by the Cool Temperate Zone with elevation varying between 2,100 and 3,300 metres (6,900 and 10,800 ft). Under Köppen's climate classification, portions of the city with lower elevations have a humid subtropical climate (Cwa), while portions of the city with higher elevations generally have a subtropical highland climate. In the Kathmandu Valley, which is representative of its valley's climate, the average summer temperature varies from 28 to 30 °C (82 to 86 °F). The average winter temperature is 10.1 °C (50.2 °F).
The city generally has a climate with warm days followed by cool nights and mornings. Unpredictable weather is expected, given that temperatures can drop to 1 °C (34 °F) or less during the winter. During a 2013 cold front, the winter temperatures of Kathmandu dropped to −4 °C (25 °F), and the lowest temperature was recorded on 10 January 2013, at −9.2 °C (15.4 °F). Rainfall is mostly monsoon-based (about 65% of the total concentrated during the monsoon months of June to August), and decreases substantially (100 to 200 cm (39 to 79 in)) from eastern Nepal to western Nepal. Rainfall has been recorded at about 1,400 millimetres (55.1 in) for the Kathmandu valley, and averages 1,407 millimetres (55.4 in) for the city of Kathmandu. On average humidity is 75%.[20][25][26] The chart below is based on data from the Nepal Bureau of Standards & Meteorology, "Weather Meteorology" for 2005. The chart provides minimum and maximum temperatures during each month. The annual amount of precipitation was 1,124 millimetres (44.3 in) for 2005, as per monthly data included in the table above.[26] The decade of 2000–2010 saw highly variable and unprecedented precipitation anomalies in Kathmandu. This was mostly due to the annual variation of the southwest monsoon.[citation needed] For example, 2003 was the wettest year ever in Kathmandu, totalling over 2,900 mm (114 in) of precipitation due to an exceptionally strong monsoon season. In contrast, 2001 recorded only 356 mm (14 in) of precipitation due to an extraordinarily weak monsoon season.
Air quality
Air pollution is a major issue in Kathmandu.[31][32][33] According to the 2016 World Health Organization's Ambient Air Pollution Database,[34] the annual average PM2.5 concentration in 2013 was 49 μg/m3, which is 4.9 times higher than recommended by the World Health Organization.[35][36] for annual average PM2.5. Starting in early 2017, the Nepali Government and US Embassy have monitored and publicly share real-time air quality data.[37][38]

Garments and woolen carpets are the most notable manufactured products.[41] Other economic sectors in Kathmandu include agriculture (9%), education (6%), transport (6%), and hotels and restaurants (5%).[41] Kathmandu is famous for lokta paper and pashmina shawls.
Tourism
Hyatt Regency, Kathmandu
Tourism is considered another important industry in Nepal. This industry started around 1950, as the country's political makeup changed and ended the country's isolation from the rest of the world. In 1956, air transportation was established and the Tribhuvan Highway, between Kathmandu and Raxaul (at India's border), was started. Separate organizations were created in Kathmandu to promote this activity; some of these include the Tourism Development Board, the Department of Tourism and the Civil Aviation Department. Furthermore, Nepal became a member of several international tourist associations. Establishing diplomatic relations with other nations further accentuated this activity. The hotel industry, travel agencies, training of tourist guides, and targeted publicity campaigns are the chief reasons for the remarkable growth of this industry in Nepal, and in Kathmandu in particular.[42]
Since then, tourism in Nepal has thrived; it is the country's most important industry.[43] Tourism is a major source of income for most of the people in the city, with several hundred thousand visitors annually. Hindu and Buddhist pilgrims from all over the world visit Kathmandu's religious sites such as Pashupatinath, Swayambhunath, Boudhanath and Budhanilkantha. From a mere 6,179 tourists in 1961/62, the number increased to 491,504 in 1999/2000. Following the end of the Maoist insurgency, there was a significant rise of 509,956 tourist arrivals in 2009. Since then, tourism has improved as the country turned into the Democratic Republic. In economic terms, the foreign exchange registered 3.8% of the GDP in 1995/96 but then started declining[why?]. The high level of tourism is attributed to the natural grandeur of the Himalayas and the rich cultural heritage of the country.[42]
The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel coined to rhyme with Thamel.[44] Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveler's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Asan is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.
With the opening of the tourist industry after the change in the political scenario of Nepal in 1950, the hotel industry drastically improved.[45] Now Kathmandu boasts several luxuries such as the Hyatt Regency, Dwarika's, theYak & Yeti, The Everest Hotel, Hotel Radisson, Hotel De L'Annapurna, The Malla Hotel, Shangri-La Hotel (which is not operated by the Shangri-La Hotel Group) and The Shanker Hotel. There are several four-star hotels such as Hotel Vaishali, Hotel Narayani, The Blue Star and Grand Hotel. The Garden Hotel, Hotel Ambassador, and Aloha Inn are among the three-star hotels in Kathmandu. Hotels like Hyatt Regency, De L'Annapurna, and Hotel Yak & Yeti are among the five-star hotels providing casinos as well.[46]
Government and public services

Civic administration
Kathmandu Municipal Corporation, abbreviated KMC, is the chief nodal agency for the administration of Kathmandu. The Municipality of Kathmandu was upgraded to incorporated in 1994.
SAARC Secretariat in Kathmandu
Metropolitan Kathmandu is divided into five sectors: the Central Sector, the East Sector, the North Sector, the City Core and the West Sector. For civic administration, the city is further divided into 35 administrative wards. The Council administers the Metropolitan area of Kathmandu city through its 177 elected representatives and 20 nominated members. It holds biannual meetings to review, process and approve the annual budget and make major policy decisions.[20][47] The ward's profile documents for the 35 wards prepared by the Kathmandu Metropolitan Council is detailed and provides information for each ward on population, the structure and condition of houses, the type of roads, educational, health and financial institutions, entertainment facilities, parking space, security provisions, etc. It also includes lists of development projects completed, on-going and planned, along with informative data about the cultural heritage, festivals, historical sites and the local inhabitants. Ward 16 is the largest, with an area of 437.4 ha; ward 26 is the smallest, with an area of 4 ha.[48]
Kathmandu is headquarters of the surrounding Kathmandu District. The city of Kathmandu forms this district with Kirtipur Municipality and some 57 Village Development Committees. According to the 2001 census, there are 235,387 households in the metropolitan city.
Law and order
The Metropolitan Police is the main law enforcement agency in the city. It is headed by a commissioner of police. The Metropolitan Police is a division of the Nepal Police, and the administrative control lies with the National Home Ministry.

Fire service
The fire service, known as the Barun Yantra Karyalaya, opened its first station in Kathmandu in 1937 with a single vehicle.[49] An iron tower was erected to monitor the city and watch for fire. As a precautionary measure, firemen were sent to the areas which were designated as accident-prone areas.[49] In 1944, the fire service was extended to the neighboring cities of Lalitpur and Bhaktapur. In 1966, a fire service was established in Kathmandu airport.[49] In 1975, a West German government donation added seven fire engines to Kathmandu's fire service.[49] The fire service in the city is also overlooked by an international non-governmental organization, the Firefighters Volunteer Association of Nepal (FAN), which was established in 2000 with the purpose of raising public awareness about fire and improving safety.[49]
Electricity and water supply
Electricity in Kathmandu is regulated and distributed by the NEA Nepal Electricity Authority. While water supply and sanitation facilities are provided by the Kathmandu Upatyaka Khanepani Limited (KUKL). There is a severe shortage of water for household purposes such as drinking, bathing, cooking and washing. People have been using mineral water bottle and mineral water tanks for all the purposes related to water. Melamchi water supply project will deliver 170 million litres per day of water by the end of 2017.
Waste management
There is no proper waste management in Kathmandu, so rubbish piles up on roads, pavements and in waterways.[50]
Waste management may be through composting in municipal waste management units, and at houses with home composting units. Both systems are common and established in India and neighbouring countries.
Demographics
Kathmandu's urban cosmopolitan character has made it the most populous city in Nepal, recording a population of 671,846 residents living in 235,387 households in the metropolitan area, according to the 2001 census.[51] According to the National Population Census of 2011, the total population of Kathmandu city was 975,543 with an annual growth rate of 6.12% with respect to the population figure of 2001. 70% of the total population residing in Kathmandu are aged between 15 and 59.
Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of 5,076.6 hectares (12,545 acres) has expanded to 8,214 hectares (20,300 acres) in 2001. With this new area, the population density which was 85 in 1991 is still 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.[52]
Ethnic groups
The largest ethnic groups are Newar (29.6%), Mongoloid (50.7%), Kirat, Gurung, Magar, Tamang, Sherpa etc.), Khas Brahmins (20.51%), and Chettris (18.5%).[53] Tamangs originating from surrounding hill districts can be seen in Kathmandu. More recently, other hill ethnic groups and Caste groups from Terai have come to represent a substantial proportion of the city's population. The major languages are Nepali and Nepal Bhasa, while English is understood by many, particularly in the service industry. The major religions in Kathmandu city are Hinduism 90% and Buddhism 20%.[citation needed]
The linguistic profile of Kathmandu underwent drastic changes during the Shah dynasty's rule because of its strong bias towards the Hindu culture. Sanskrit language therefore was preferred and people were encouraged to learn it even by attending Sanskrit learning centers in Terai. Sanskrit schools were specially set up in Kathmandu and in the Terai region to inculcate traditional Hindu culture and practices originated from Nepal.[54]

The ancient trade route between India and Tibet that passed through Kathmandu enabled a fusion of artistic and architectural traditions from other cultures to be amalgamated with local art and architecture.[55] The monuments of Kathmandu City have been influenced over the centuries by Hindu and Buddhist religious practices. The architectural treasure of the Kathmandu valley has been categorized under the well-known seven groups of heritage monuments and buildings. In 2006 UNESCO declared these seven groups of monuments as a World Heritage Site (WHS). The seven monuments zones cover an area of 189 hectares (470 acres), with the buffer zone extending to 2,394 hectares (5,920 acres). The Seven Monument Zones (Mzs) inscribed originally in 1979 and with a minor modification in 2006 are Durbar squares of Hanuman Dhoka, Patan and Bhaktapur, Hindu temples of Pashupatinath and Changunarayan, the Buddhist stupas of Swayambhu and Boudhanath.[56][57]
Durbar squares
Main articles: Kathmandu Durbar Square and Hanuman Dhoka
The literal meaning of Durbar Square is a "place of palaces". There are three preserved Durbar Squares in Kathmandu valley and one unpreserved in Kirtipur. The Durbar Square of Kathmandu is in the old city and has heritage buildings representing four kingdoms (Kantipur, Lalitpur, Bhaktapur, Kirtipur); the earliest is the Licchavi dynasty. The complex has 50 temples and is distributed in two quadrangles of the Durbar Square. The outer quadrangle has the Kasthamandap, Kumari Ghar, and Shiva-Parvati Temple; the inner quadrangle has the Hanuman Dhoka palace. The squares were severely damaged in the April 2015 Nepal earthquake.
Hanuman Dhoka is a complex of structures with the Royal Palace of the Malla kings and of the Shah dynasty. It is spread over five acres. The eastern wing, with ten courtyards, is the oldest part, dating to the mid-16th century. It was expanded by King Pratap Malla in the 17th century with many temples. The royal family lived in this palace until 1886 when they moved to Narayanhiti Palace. The stone inscription outside is in fifteen languages.[58]
Kumari Ghar is a palace in the center of the Kathmandu city, next to the Durbar square where a Royal Kumari selected from several Kumaris resides. Kumari, or Kumari Devi, is the tradition of worshipping young pre-pubescent girls as manifestations of the divine female energy or devi in South Asian countries. In Nepal the selection process is very rigorous. Kumari is believed to be the bodily incarnation of the goddess Taleju (the Nepali name for Durga) until she menstruates, after which it is believed that the goddess vacates her body. Serious illness or a major loss of blood from an injury are also causes for her to revert to common status. The current Royal Kumari, Matina Shakya, age four, was installed in October 2008 by the Maoist government that replaced the monarchy.[59]
Kasthamandap is a three-storeyed temple enshrining an image of Gorakhnath. It was built in the 16th century in pagoda style. The name of Kathmandu is a derivative of the word Kasthamandap. It was built under the reign of King Laxmi Narsingha Malla. Kasthamandap stands at the intersection of two ancient trade routes linking India and Tibet at Maru square. It was originally built as a rest house for travelers.
Pashupatinath temple

Panorama of the Pashupatinath Temple from the other bank of Bagmati river
Pashupatinath temple,kathmandu,Nepal.jpg
The Pashupatinath Temple is a famous 5th century Hindu temple dedicated to Lord Shiva (Pashupati). On the banks of the Bagmati River in the eastern part of Kathmandu, Pashupatinath Temple is the oldest Hindu temple in Kathmandu.[60] It served as the seat of national deity, Lord Pashupatinath, until Nepal was secularized. However, a significant part of the temple was destroyed by Mughal invaders in the 14th century and little or nothing remains of the original 5th-century temple exterior. The temple as it stands today was built in the 19th century, although the image of the bull and the black four-headed image of Pashupati are at least 300 years old.[61] The temple is a UNESCO World Heritage Site.[61][62] Shivaratri, or the night of Lord Shiva, is the most important festival that takes place here, attracting thousands of devotees and sadhus.[citation needed]
Believers in Pashupatinath (mainly Hindus) are allowed to enter the temple premises, but non-Hindu visitors are allowed to view the temple only from the across the Bagmati River.[61] The priests who perform the services at this temple have been Brahmins from Karnataka, South India since the time of Malla king Yaksha Malla.[63] This tradition is believed to have been started at the request of Adi Shankaracharya who sought to unify the states of Bharatam (Unified India) by encouraging cultural exchange. This procedure is followed in other temples around India, which were sanctified by Adi Shankaracharya.
The temple is built in the pagoda style of architecture, with cubic constructions, carved wooden rafters (tundal) on which they rest, and two-level roofs made of copper and gold.
Boudhanath
Buildings around Boudha Stupa
The Boudhanath, (also written Bouddhanath, Bodhnath, Baudhanath or the Khāsa Chaitya), is one of the holiest Buddhist sites in Nepal, along with Swayambhu. It is a very popular tourist site. Boudhanath is known as Khāsti by Newars and as Bauddha or Bodhnāth by speakers of Nepali.[64] About 11 km (7 mi) from the center and northeastern outskirts of Kathmandu, the stupa's massive mandala makes it one of the largest spherical stupas in Nepal.[65] Boudhanath became a UNESCO World Heritage Site in 1979.
Boudhanath Stupa, one of the largest in Nepal
The base of the stupa has 108 small depictions of the Dhyani Buddha Amitabha. It is surrounded with a brick wall with 147 niches, each with four or five prayer wheels engraved with the mantra, om mani padme hum.[66] At the northern entrance where visitors must pass is a shrine dedicated to Ajima, the goddess of smallpox.[66] Every year the stupa attracts many Tibetan Buddhist pilgrims who perform full body prostrations in the inner lower enclosure, walk around the stupa with prayer wheels, chant, and pray.[66] Thousands of prayer flags are hoisted up from the top of the stupa downwards and dot the perimeter of the complex. The influx of many Tibetan refugees from China has seen the construction of over 50 Tibetan gompas (monasteries) around Boudhanath.
Swayambhu
Main article: Swayambhunath
Swayambhu is a Buddhist stupa atop a hillock at the northwestern part of the city. This is among the oldest religious sites in Nepal. Although the site is considered Buddhist, it is revered by both Buddhists and Hindus. The stupa consists of a dome at the base; above the dome, there is a cubic structure with the eyes of Buddha looking in all four directions.[clarification needed] There are pentagonal Toran above each of the four sides, with statues engraved on them. Behind and above the torana there are thirteen tiers. Above all the tiers, there is a small space above which lies a gajur.
Rani Pokhari
Main article: Ranipokhari
Ranipokhari is a historic artificial pond in the heart of Kathmandu. It was built by king Pratap Mall in 1670 AD. A large stone statue of an elephant in south signifies the image of Pratap Malla and his two sons. Rani Pokhari is opened once a year during the final day of Tihar i.e. Bhai Tika and Chhath festival. The world largest Chhath takes place every year in Ranipokhari. The pond is one of Kathmandu's most famous landmarks and is known for its religious and aesthetic significance.

Arts
Kathmandu valley is described as "an enormous treasure house of art and sculptures", which are made of wood, stone, metal, and terracotta, and found in profusion in temples, shrines, stupas, gompas, chaityasm and palaces. The art objects are also seen in street corners, lanes, private courtyards and in open ground. Most art is in the form of icons of gods and goddesses. Kathmandu valley has had this art treasure for a very long time, but received worldwide recognition only after the country opened to the outside world in 1950.[54]
The religious art of Nepal and Kathmandu in particular consists of an iconic symbolism of the Mother Goddesses such as: Bhavani, Durga, Gaja-Lakshmi, Hariti-Sitala, Mahsishamardini, Saptamatrika (seven mother goddesses), and Sri-Lakshmi(wealth-goddess). From the 3rd century BCE, apart from the Hindu gods and goddesses, Buddhist monuments from the Ashokan period (it is said that Ashoka visited Nepal in 250 BC) have embellished Nepal in general and the valley in particular. These art and architectural edifices encompass three major periods of evolution: the Licchavi or classical period (500 to 900 AD), the post-classical period (1000 to 1400 AD), with strong influence of the Palla art form; the Malla period (1400 onwards) that exhibited explicitly tantric influences coupled with the art of Tibetan Demonology.[67]
A broad typology has been ascribed to the decorative designs and carvings created by the people of Nepal. These artists have maintained a blend of Hinduism and Buddhism. The typology, based on the type of material used are: stone art, metal art, wood art, terracotta art, and painting.[68]
Museums
Kathmandu is home to a number of museums and art galleries, including the National Museum of Nepal and the Natural History Museum of Nepal. Nepal's art and architecture is an amalgamation of two ancient religions, Hinduism and Buddhhism. These are amply reflected in the many temples, shrines, stupas, monasteries, and palaces in the seven well-defined Monument Zones of the Kathmandu valley are part of a UNESCO World Heritage Site. This amalgamation is also reflected in the planning and exhibitions in museums and art galleries throughout Kathmandu and its sister cities of Patan and Bhaktapur. The museums display unique artifacts and paintings from the 5th century CE to the present day, including archeological exportation.[69]

CAUCORP Sentinel ASN (Advanced Seeker and Neutralizer)
Upon the discovery of the ocean planet Broncus, and soon after, the vast and valuable mineral deposits hidden in pockets underneath the ocean floor - a race began. A race of incredible magnitude - only the fiercest competitors were destined to win.
Designed by the brilliant minds at the Anarcha Research Institute, the Sentinel Advanced Seeker and Neutralizer is our solution for underwater warfare - created after months of meticulous research and development. Unlike its competitors, the Sentinel is very simple and doesn’t use as many exotic materials - all while retaining a durability and strength that CAUCORP and ARI is reknown for. While designed right after the discovery of Broncus for use on this planet, we foresee further uses of the design in terrestrial and extraterrestrial environments.
[The Complex is owned by Consolidated American Universal Megacorporation, the largest and most powerful syndicate in North America. The weapon is currently being contracted primarily for the United States of America and Canada.]
Primary Weapon Aspects and Operations:
Built on a bulky base platform housing a multistage coilgun, the Sentinel is a heavy gun, requiring an exosuit to hold and fire properly - granted when working under heavy pressure. The firing system consists of a powerful Kai Cheng 10-stage modular segmented electromagnetic coil (pure iron-copper) wrapped around a smoothbore barrel (molybdenum-chromium-steel alloy and ceramic composite firing chamber). It is designed to propel a long, thin flechette round through a liquid of high viscosity. In a way, it fires a micro-torpedo - a self-guiding bullet. [The modular coil design allows for a single or multiple sections to be replaced without taking the whole firing system out. For example, should the secondary forward accelerator gets smashed, it can be taken out individually and replaced without taking out the surrounding accelerators. With a proper engineer on duty, the fix should take about half an hour maximum.]
The weapon chassis is a pressure-resistant container constructed of pressure treated steel-tungsten-carbon superalloy with a molybdenum frame, and a titanium-steel-chromium alloy shell. This chassis is designed solely to avoid any oxidation, resist pressure successfully, and disperse force. The frame is imbedded with two networks of highly monitored cooling tubes separated from the environment. The primary networks consistently run liquid nitrogen coolant around the coils and power plant, while the secondary network runs nothing but diluted liquid hydrogen around the muzzle and supercapacitor. The secondary network shoots a drop of pure liquid hydrogen coolant into the diluted stream every time the weapon fires, negating the heat produced by the friction and the power modulators. [It is to be noted that the water at deep ocean level on Broncus averages about 5°C to 10°C in temperature, enough to keep the system cooled in non-prolonged firing (3 rounds or less). However, we would advise against taking the cooling system out as it is crucial to cooling the computer guidance units, power modulators, and supercapacitor.]
Targeting Systems:
The TeleCentral Acoustic Hyperlens and Imager (AHI) mounted into the weapon system provides an extremely accurate combined sonar-based and infrared image of the target and obstacles between the weapon, round, and target. The Hyperlens is a wide brass lense that uses pulse-echo sonic technology to image the area. Combined with the rounds’ own heat-seeking system, the Shintaro Line BBPORT targeting computer in the weapon can easily calculate and recalculate a rounds trajectory to avoid obstacles and hit a moving target, all within crucial nanoseconds. Due to this, ammunition is not expended at a fast rate as it is with a conventional rifle; instead, a single round can easily find its target around obstacles, allowing for the weapon to expend less ammunition and fire from behind cover (sonar system works through all cover). [However, since sound waves travel relatively slowly compared to electromagnetic waves, the weapon is usually less than a second behind the projectile in information. An advanced prediction and synchronization algorithm created by Dr. Liam Connaught’s team compensates for this.]
Ammunition:
There is a wide variety of ammunition available for use with this rifle. Each round consists of 3 distinct ‘groupings’.
The ‘chassis’ of any round consists of a non-conductive but highly ferromagnetic ceramic-magnet composite with soft iron support, designed to withstand heat, pressure, and be quite sturdy in shape. The chassis is very thin and boasts four extendable pivoting fins.
Each chassis contains the ‘electronic’ and ‘warhead’ components. The electronic component consists of a small package including a transmitterbot, four microservos, and an accurate infrared imaging system. The high-end Shintaro Line transmitterbot receives instructions from the infrared imager, information and confirmation from the parent transmitter, and pivots the microservos to align the fins towards the target designated by the rifle.
‘Warheads’, so to speak, are mounted directly into the chassis, with the protruding front being aquadynamic.
The RBB-5 Tranquilizer Dart has a very sharp, thick needle for the front. Once it hits and penetrates a surface, it injects a highly effective synthetic etorphine, which immediately permeates through to an animal’s circulatory system and causes unconsciousness. One dose is enough to sedate an animal twice the size of an adult elephant, but is only fatal in doses larger than 3 ‘warheads’ - users must consider that firing over 3 rounds at a time can cause death. [Dr. Sonya’s team designed the warhead in response to the overwhelming public disapproval to killing the alien life forms on the Broncus. We do not share or reject their sentiment, and only wish to provide CAUCORP and the purchasers with versatility.]
The Kraig 45 Standard is considered standard ammunition for the Sentinel by our team. The Kraig round comes in several special variations including HE, Caustic, and Tracer, but Kraig Standard is by far the most common and easy to manufacture. It is simply a tungsten-weighted aquadynamic warhead capable of penetrating the thickest surface with kinetic force using a patented shape.
Trinity Longbow Self-Propelled ammunition is extremely potent, in that it has the longest range of the listed warheads. It is, however, more expensive - the warhead isn’t only propelled by the electromagnetic coils in the weapon, but also by a micro turboshaft mounted in the nose. The range on this projectile easily surpasses 4-5 kilometers and is much more effective in strong currents than the aforementioned warheads. However, this mechanism takes up too much space in the projectile for any advanced warheads to be installed, so it simply serves as a kinetic projectile. The Trinity Harpoon is a variation of this projectile that not only penetrates a beasts skin, but also leaves a trail of synthetic silk high-tensile wire laced with strands of carbon fiber - an extremely strong and unbreakable wire that can withstand many tons of force in either direction, that also sinks to the ocean floor. However, it is not wise to use Trinity Harpoon in a handheld Sentinel, because we presume that the larger animals on the planet can rip the weapon out of an operator's arms quite easily. [We believe that our engineering team could produce a cheaper and more versatile version of the Trinity warhead with more funding and at least another two years of development - we currently do not have the technology to miniaturize the power module for the turboshaft.]
Power Storage and Distribution:
The Sentinel utilizes an integrated Steinbek GCNS-5m (Graphene - Carbon Nanotube Supercapacitor) for firing the weapon (powering the coils, capacitor bank). In essence, the device consists of a series of ultra-thin graphene films held in place by a structure of carbon nanotubes, giving the film a massive surface area without any aggregation. This “ultracapacitor” (as our team came to call it) can hold a charge for much longer than any known miniaturized capacitor in the world, and is equally potent as the competitor’s battery models in storing energy. However, unlike batteries, the ultracapacitor can charge and discharge much faster and more efficiently - and, due to the lack of reliance on chemical compositions, it is much more reliable than any battery when encountering foreign substances and undesirable temperatures. This allows us to channel as much power as we want into the coilgun capacitor banks, as the ultracapacitor is designed for releasing huge amounts of energy in pulses. The GCNS-5m can be charged to full capacity within a period of less than 5 minutes.
Handling (Recoil):
The much higher force exerted towards the rear onto the operator (due to the extremely high power multistage coilgun) was a staggering issue in initial tests of the prototype. Considering a minimum-power standard issue American EP-5 powered exoskeleton would only take care of about 6% of the total force exerted backwards and none of the muzzle rise, the weapon required it’s own recoil absorption system.
Dr. Bahnstein’s design team came up with a two-stage buffer and bolt system to minimize muzzle climb. Inspired by the KRISS Zenith, they devised an active method of recoil control in which the heavy steel-composite bolt would slide rearwards and downwards into a chamber behind the magazine before chambering a new round. Acting as a counterweight, an opposite force to the one causing the weapon to rise, the bolt removes a large amount of muzzle climb. This is combined with a passive aspect: the accelerator section is suspended within the framework of the weapon by a structure of titanium and steel polymer composite supports.
The rearwards recoil impulse was taken care of by Mr. Nnamani’s synthetics team. Through installing a skeleton of shock absorbing titanium alloys into the hollow stock chassis, and filling the framework with sorbothane cells (synthetic viscoelastic polyurethane gel) sealed in neoprene synthetic rubber, recoil is reduced to a negligible fraction. The sorbothane buffers absorb much of the shock that originates from the coilgun mechanism while the neoprene protects the sorbothane substance from potentially harmful chemical substances in the ocean water.
