Concrete pillboxes built to replicate Nazi bunkers rest on an old cattle farm now an area of critical environmental concern managed by the BLM in southwest Oregon, Sept. 26, 2018. BLM photo: Matt Christenson
A quiet oak savanna in southwest Oregon has a World War II story to tell.
It was the summer of 1942 when thousands of young American troops started arriving in Oregon to prepare for battle.
Only months prior, immediately after the Japanese bombing of Pearl Harbor and America’s entry into WWII, the U.S. Army broke ground on Camp White, a massively ambitious training ground for troops north of Medford.
The national war effort was ramping up, and from the rationing at home to the drill sergeants yelling at new draftees, the task at hand was unified: Get America prepared for war as fast as possible.
At Camp White, in the heart of the Rogue River Valley, it got loud very quick.
Construction crews worked 24 hours a day until the base, consisting of 1,300 structures, was complete. Barracks, mess halls, a railroad, full electrical grid and sewer system were all built in six months.
And then the troops arrived.
The newly reinstated 91st Division went on 91-mile-long hikes.
They fired bazookas, mortars and tanks.
And they attacked concrete pillboxes built to replicate Nazi bunkers.
Despite creating what was then Oregon’s second most populous city at 40,000 people, there are now only a few lasting structures proving Camp White ever existed. Sadly, there are even fewer first-hand memories.
The pillboxes are still standing, though. They simultaneously represent a mostly forgotten military legacy and since 2013, an opportunity for historic preservation.
After decades of private cattle farming, Camp White’s pillboxes now rest on public land.

Replicating a quarry scene of times past, William Bagnall 0-4-0ST 'Peter' (works No.2067 built in 1917) couples up to skips at the Lime Kiln sidings as 'Wendy' (works No.2091 built in 1919) waits to enter the sidings. 'Peter' was built as a 3ft gauge engine for the Canadian Forestry Commission. However due to cessation of hostilities it was returned to the manufacturer and, after being re-gauged to 2ft, it was put to work at the Cliffe Hill Quarry Company. It entered preservation in the late 1960's and was moved to the Brockham Museum near Dorking in Surrey until its closure in 1982, when it was transferred to Amberley Museum. The locomotive had at this time just recently returned to service after a six-year restoration project.

This handle makes it easy to reach deeply into the 3D printer while calibrating and levelling the build platform. It is designed to hold a standard Post-it sticky paper on it's tip.
In most cases the optimal gap between a 3D printer's platform and the extruder's hot-end tip, is 0,1 mm. A common practice is to use a simple sheet of paper and place it on top of the build platform just under the extruder's tip.
The platform is then adjusted to only just let the paper slide freely. The adjustment must be made on all corners and the centre of the build plate until it is perfectly level.
• Download the STL file
• 3D-print it
• Grab a Post-it sticky of your preferred colour
• Stick it on the flat front end of the 3D-printed handle
• Set-up you 3D-printer for levelling the platform
• Place the paper between the the platform and the extruder tip
• Adjust the build plate's screws and move the handle slightly to make the paper slide under the extruder tip
• When you feel a slight friction stop adjusting the screw
• Repeat this process on all corners and centre of the platform until you can feel the same friction on all spots
Make sure that you only use one sheet of Post-it paper and if unsure control-measure it with a calliper to verify 0.1 mm thickness.
After calibrating your Replicator's platform it should remain level for a long time. Until you need to calibrate it next time you can use this Post-it handle for other purposes as follows:
• A very gentle fly-swat (PETA-certified ;)
• A small sign holder you can use to communicate short messages to your office mates

The Ajanta Caves (Ajiṇṭhā leni; Marathi: अजिंठा लेणी) in Aurangabad district of Maharashtra, India are about 30 rock-cut Buddhist cave monuments which date from the 2nd century BCE to about 480 or 650 CE. The caves include paintings and sculptures described by the government Archaeological Survey of India as "the finest surviving examples of Indian art, particularly painting", which are masterpieces of Buddhist religious art, with figures of the Buddha and depictions of the Jataka tales. The caves were built in two phases starting around the 2nd century BCE, with the second group of caves built around 400–650 CE according to older accounts, or all in a brief period of 460 to 480 according to the recent proposals of Walter M. Spink. The site is a protected monument in the care of the Archaeological Survey of India, and since 1983, the Ajanta Caves have been a UNESCO World Heritage Site.
The caves are located in the Indian state of Maharashtra, near Jalgaon and just outside the village of Ajinṭhā 20°31′56″N 75°44′44″E), about 59 kilometres from Jalgaon railway station on the Delhi – Mumbai line and Howrah-Nagpur-Mumbai line of the Central Railway zone, and 104 kilometres from the city of Aurangabad. They are 100 kilometres from the Ellora Caves, which contain Hindu and Jain temples as well as Buddhist caves, the last dating from a period similar to Ajanta. The Ajanta caves are cut into the side of a cliff that is on the south side of a U-shaped gorge on the small river Waghur, and although they are now along and above a modern pathway running across the cliff they were originally reached by individual stairs or ladders from the side of the river 35 to 110 feet below.
The area was previously heavily forested, and after the site ceased to be used the caves were covered by jungle until accidentally rediscovered in 1819 by a British officer on a hunting party. They are Buddhist monastic buildings, apparently representing a number of distinct "monasteries" or colleges. The caves are numbered 1 to 28 according to their place along the path, beginning at the entrance. Several are unfinished and some barely begun and others are small shrines, included in the traditional numbering as e.g. "9A"; "Cave 15A" was still hidden under rubble when the numbering was done. Further round the gorge are a number of waterfalls, which when the river is high are audible from outside the caves.
The caves form the largest corpus of early Indian wall-painting; other survivals from the area of modern India are very few, though they are related to 5th-century paintings at Sigiriya in Sri Lanka. The elaborate architectural carving in many caves is also very rare, and the style of the many figure sculptures is highly local, found only at a few nearby contemporary sites, although the Ajanta tradition can be related to the later Hindu Ellora Caves and other sites.
HISTORY
Like the other ancient Buddhist monasteries, Ajanta had a large emphasis on teaching, and was divided into several different caves for living, education and worship, under a central direction. Monks were probably assigned to specific caves for living. The layout reflects this organizational structure, with most of the caves only connected through the exterior. The 7th-century travelling Chinese scholar Xuanzang informs us that Dignaga, a celebrated Buddhist philosopher and controversialist, author of well-known books on logic, lived at Ajanta in the 5th century. In its prime the settlement would have accommodated several hundred teachers and pupils. Many monks who had finished their first training may have returned to Ajanta during the monsoon season from an itinerant lifestyle.
The caves are generally agreed to have been made in two distinct periods, separated by several centuries.
CAVES OF THE FIRST (SATAVAHANA) PERIOD
The earliest group of caves consists of caves 9, 10, 12, 13 and 15A. According to Walter Spink, they were made during the period 100 BCE to 100 CE, probably under the patronage of the Satavahana dynasty (230 BCE – c. 220 CE) who ruled the region. Other datings prefer the period 300 BCE to 100 BCE, though the grouping of the earlier caves is generally agreed. More early caves may have vanished through later excavations. Of these, caves 9 and 10 are stupa halls of chaitya-griha form, and caves 12, 13, and 15A are vihāras (see the architecture section below for descriptions of these types). The first phase is still often called the Hinayāna phase, as it originated when, using traditional terminology, the Hinayāna or Lesser Vehicle tradition of Buddhism was dominant, when the Buddha was revered symbolically. However the use of the term Hinayana for this period of Buddhism is now deprecated by historians; equally the caves of the second period are now mostly dated too early to be properly called Mahayana, and do not yet show the full expanded cast of supernatural beings characteristic of that phase of Buddhist art. The first Satavahana period caves lacked figurative sculpture, emphasizing the stupa instead, and in the caves of the second period the overwhelming majority of images represent the Buddha alone, or narrative scenes of his lives.
Spink believes that some time after the Satavahana period caves were made the site was abandoned for a considerable period until the mid-5th century, probably because the region had turned mainly Hindu
CAVES OF THE LATER OR VAKATAKA PERIOD
The second phase began in the 5th century. For a long time it was thought that the later caves were made over a long period from the 4th to the 7th centuries CE, but in recent decades a series of studies by the leading expert on the caves, Walter M. Spink, have argued that most of the work took place over the very brief period from 460 to 480 CE, during the reign of Emperor Harishena of the Vakataka dynasty. This view has been criticized by some scholars, but is now broadly accepted by most authors of general books on Indian art, for example Huntington and Harle.
The second phase is still often called the Mahāyāna or Greater Vehicle phase, but scholars now tend to avoid this nomenclature because of the problems that have surfaced regarding our understanding of Mahāyāna.
Some 20 cave temples were simultaneously created, for the most part viharas with a sanctuary at the back. The most elaborate caves were produced in this period, which included some "modernization" of earlier caves. Spink claims that it is possible to establish dating for this period with a very high level of precision; a fuller account of his chronology is given below. Although debate continues, Spink's ideas are increasingly widely accepted, at least in their broad conclusions. The Archaeological Survey of India website still presents the traditional dating: "The second phase of paintings started around 5th – 6th centuries A.D. and continued for the next two centuries". Caves of the second period are 1–8, 11, 14–29, some possibly extensions of earlier caves. Caves 19, 26, and 29 are chaitya-grihas, the rest viharas.
According to Spink, the Ajanta Caves appear to have been abandoned by wealthy patrons shortly after the fall of Harishena, in about 480 CE. They were then gradually abandoned and forgotten. During the intervening centuries, the jungle grew back and the caves were hidden, unvisited and undisturbed, although the local population were aware of at least some of them.
REDISCOVERY
On 28 April 1819, a British officer for the Madras Presidency, John Smith, of the 28th Cavalry, while hunting tiger, accidentally discovered the entrance to Cave No. 10 deep within the tangled undergrowth. There were local people already using the caves for prayers with a small fire, when he arrived. Exploring that first cave, long since a home to nothing more than birds and bats and a lair for other larger animals, Captain Smith vandalized the wall by scratching his name and the date, April 1819. Since he stood on a five-foot high pile of rubble collected over the years, the inscription is well above the eye-level gaze of an adult today. A paper on the caves by William Erskine was read to the Bombay Literary Society in 1822. Within a few decades, the caves became famous for their exotic setting, impressive architecture, and above all their exceptional, all but unique paintings. A number of large projects to copy the paintings were made in the century after rediscovery, covered below. In 1848 the Royal Asiatic Society established the "Bombay Cave Temple Commission" to clear, tidy and record the most important rock-cut sites in the Bombay Presidency, with John Wilson, as president. In 1861 this became the nucleus of the new Archaeological Survey of India. Until the Nizam of Hyderabad built the modern path between the caves, among other efforts to make the site easy to visit, a trip to Ajanta was a considerable adventure, and contemporary accounts dwell with relish on the dangers from falls off narrow ledges, animals and the Bhil people, who were armed with bows and arrows and had a fearsome reputation.
Today, fairly easily combined with Ellora in a single trip, the caves are the most popular tourist destination in Mahrashtra, and are often crowded at holiday times, increasing the threat to the caves, especially the paintings. In 2012, the Maharashtra Tourism Development Corporation announced plans to add to the ASI visitor centre at the entrance complete replicas of caves 1, 2, 16 & 17 to reduce crowding in the originals, and enable visitors to receive a better visual idea of the paintings, which are dimly-lit and hard to read in the caves. Figures for the year to March 2010 showed a total of 390,000 visitors to the site, divided into 362,000 domestic and 27,000 foreign. The trends over the previous few years show a considerable growth in domestic visitors, but a decline in foreign ones; the year to 2010 was the first in which foreign visitors to Ellora exceeded those to Ajanta.
PAINTINGS
Mural paintings survive from both the earlier and later groups of caves. Several fragments of murals preserved from the earlier caves (Caves 9 and 11) are effectively unique survivals of court-led painting in India from this period, and "show that by Sātavāhana times, if not earlier, the Indian painter had mastered an easy and fluent naturalistic style, dealing with large groups of people in a manner comparable to the reliefs of the Sāñcī toraņa crossbars".
Four of the later caves have large and relatively well-preserved mural paintings which "have come to represent Indian mural painting to the non-specialist", and fall into two stylistic groups, with the most famous in Caves 16 and 17, and apparently later paintings in Caves 1 and 2. The latter group were thought to be a century or more later than the others, but the revised chronology proposed by Spink would place them much closer to the earlier group, perhaps contemporary with it in a more progressive style, or one reflecting a team from a different region. The paintings are in "dry fresco", painted on top of a dry plaster surface rather than into wet plaster.
All the paintings appear to be the work of painters at least as used to decorating palaces as temples, and show a familiarity with and interest in details of the life of a wealthy court. We know from literary sources that painting was widely practised and appreciated in the courts of the Gupta period. Unlike much Indian painting, compositions are not laid out in horizontal compartments like a frieze, but show large scenes spreading in all directions from a single figure or group at the centre. The ceilings are also painted with sophisticated and elaborate decorative motifs, many derived from sculpture. The paintings in cave 1, which according to Spink was commissioned by Harisena himself, concentrate on those Jataka tales which show previous lives of the Buddha as a king, rather than as an animal or human commoner, and so show settings from contemporary palace life.
In general the later caves seem to have been painted on finished areas as excavating work continued elsewhere in the cave, as shown in caves 2 and 16 in particular. According to Spink's account of the chronology of the caves, the abandonment of work in 478 after a brief busy period accounts for the absence of painting in caves such as 4 and 17, the later being plastered in preparation for paintings that were never done.
COPIES
The paintings have deteriorated significantly since they were rediscovered, and a number of 19th-century copies and drawings are important for a complete understanding of the works. However, the earliest projects to copy the paintings were plagued by bad fortune. In 1846, Major Robert Gill, an Army officer from Madras presidency and a painter, was appointed by the Royal Asiatic Society to replicate the frescoes on the cave walls to exhibit these paintings in England. Gill worked on his painting at the site from 1844 to 1863 (though he continued to be based there until his death in 1875, writing books and photographing) and made 27 copies of large sections of murals, but all but four were destroyed in a fire at the Crystal Palace in London in 1866, where they were on display.
Another attempt was made in 1872 when the Bombay Presidency commissioned John Griffiths, then principal of the Bombay School of Art, to work with his students to make new copies, again for shipping to England. They worked on this for thirteen years and some 300 canvases were produced, many of which were displayed at the Imperial Institute on Exhibition Road in London, one of the forerunners of the Victoria and Albert Museum. But in 1885 another fire destroyed over a hundred paintings that were in storage. The V&A still has 166 paintings surviving from both sets, though none have been on permanent display since 1955. The largest are some 3 × 6 metres. A conservation project was undertaken on about half of them in 2006, also involving the University of Northumbria. Griffith and his students had unfortunately painted many of the paintings with "cheap varnish" in order to make them easier to see, which has added to the deterioration of the originals, as has, according to Spink and others, recent cleaning by the ASI.
A further set of copies were made between 1909 and 1911 by Christiana Herringham (Lady Herringham) and a group of students from the Calcutta School of Art that included the future Indian Modernist painter Nandalal Bose. The copies were published in full colour as the first publication of London's fledgling India Society. More than the earlier copies, these aimed to fill in holes and damage to recreate the original condition rather than record the state of the paintings as she was seeing them. According to one writer, unlike the paintings created by her predecessors Griffiths and Gill, whose copies were influenced by British Victorian styles of painting, those of the Herringham expedition preferred an 'Indian Renascence' aesthetic of the type pioneered by Abanindranath Tagore.
Early photographic surveys were made by Robert Gill, who learnt to use a camera from about 1856, and whose photos, including some using stereoscopy, were used in books by him and Fergusson (many are available online from the British Library), then Victor Goloubew in 1911 and E.L. Vassey, who took the photos in the four volume study of the caves by Ghulam Yazdani (published 1930–1955).
ARCHITECTURE
The monasteries mostly consist of vihara halls for prayer and living, which are typically rectangular with small square dormitory cells cut into the walls, and by the second period a shrine or sanctuary at the rear centred on a large statue of the Buddha, also carved from the living rock. This change reflects the movement from Hinayana to Mahāyāna Buddhism. The other type of main hall is the narrower and higher chaitya hall with a stupa as the focus at the far end, and a narrow aisle around the walls, behind a range of pillars placed close together. Other plainer rooms were for sleeping and other activities. Some of the caves have elaborate carved entrances, some with large windows over the door to admit light. There is often a colonnaded porch or verandah, with another space inside the doors running the width of the cave.
The central square space of the interior of the viharas is defined by square columns forming a more or less square open area. Outside this are long rectangular aisles on each side, forming a kind of cloister. Along the side and rear walls are a number of small cells entered by a narrow doorway; these are roughly square, and have small niches on their back walls. Originally they had wooden doors. The centre of the rear wall has a larger shrine-room behind, containing a large Buddha statue. The viharas of the earlier period are much simpler, and lack shrines. Spink in fact places the change to a design with a shrine to the middle of the second period, with many caves being adapted to add a shrine in mid-excavation, or after the original phase.
The plan of Cave 1 shows one of the largest viharas, but is fairly typical of the later group. Many others, such as Cave 16, lack the vestibule to the shrine, which leads straight off the main hall. Cave 6 is two viharas, one above the other, connected by internal stairs, with sanctuaries on both levels.
The four completed chaitya halls are caves 9 and 10 from the early period, and caves 19 and 26 from the later period of construction. All follow the typical form found elsewhere, with high ceilings and a central "nave" leading to the stupa, which is near the back, but allows walking behind it, as walking around stupas was (and remains) a common element of Buddhist worship (pradakshina). The later two have high ribbed roofs, which reflect timber forms, and the earlier two are thought to have used actual timber ribs, which have now perished. The two later halls have a rather unusual arrangement (also found in Cave 10 at Ellora) where the stupa is fronted by a large relief sculpture of the Buddha, standing in Cave 19 and seated in Cave 26. Cave 29 is a late and very incomplete chaitya hall.
The form of columns in the work of the first period is very plain and un-embellished, with both chaitya halls using simple octagonal columns, which were painted with figures. In the second period columns were far more varied and inventive, often changing profile over their height, and with elaborate carved capitals, often spreading wide. Many columns are carved over all their surface, some fluted and others carved with decoration all over, as in cave 1.
The flood basalt rock of the cliff, part of the Deccan Traps formed by successive volcanic eruptions at the end of the Cretaceous, is layered horizontally, and somewhat variable in quality, so the excavators had to amend their plans in places, and in places there have been collapses in the intervening centuries, as with the lost portico to cave 1. Excavation began by cutting a narrow tunnel at roof level, which was expanded downwards and outwards; the half-built vihara cave 24 shows the method. Spink believes that for the first caves of the second period the excavators had to relearn skills and techniques that had been lost in the centuries since the first period, which were then transmitted to be used at later rock-cut sites in the region, such as Ellora, and the Elephanta, Bagh, Badami and Aurangabad Caves.
The caves from the first period seem to have been paid for by a number of different patrons, with several inscriptions recording the donation of particular portions of a single cave, but according to Spink the later caves were each commissioned as a complete unit by a single patron from the local rulers or their court elites. After the death of Harisena smaller donors got their chance to add small "shrinelets" between the caves or add statues to existing caves, and some two hundred of these "intrusive" additions were made in sculpture, with a further number of intrusive paintings, up to three hundred in cave 10 alone.
A grand gateway to the site, at the apex of the gorge's horsehoe between caves 15 and 16, was approached from the river, and is decorated with elephants on either side and a nāga, or protective snake deity.
ICONOGRAPHY OF THE CAVES
In the pre-Christian era, the Buddha was represented symbolically, in the form of the stupa. Thus, halls were made with stupas to venerate the Buddha. In later periods the images of the Buddha started to be made in coins, relic caskets, relief or loose sculptural forms, etc. However, it took a while for the human representation of the Buddha to appear in Buddhist art. One of the earliest evidences of the Buddha's human representations are found at Buddhist archaeological sites, such as Goli, Nagarjunakonda, and Amaravati. The monasteries of those sites were built in less durable media, such as wood, brick, and stone. As far as the genre of rock-cut architecture is concerned it took many centuries for the Buddha image to be depicted. Nobody knows for sure at which rock-cut cave site the first image of the Buddha was depicted. Current research indicates that Buddha images in a portable form, made of wood or stone, were introduced, for the first time, at Kanheri, to be followed soon at Ajanta Cave 8 (Dhavalikar, Jadhav, Spink, Singh). While the Kanheri example dates to 4th or 5th century CE, the Ajanta example has been dated to c. 462–478 CE (Spink). None of the rock-cut monasteries prior to these dates, and other than these examples, show any Buddha image although hundreds of rock-cut caves were made throughout India during the first few centuries CE. And, in those caves, it is the stupa that is the object of veneration, not the image. Images of the Buddha are not found in Buddhist sailagrhas (rock-cut complexes) until the times of the Kanheri (4th–5th century CE) and Ajanta examples (c. 462–478 CE).
The caves of the second period, now all dated to the 5th century, were typically described as "Mahayana", but do not show the features associated with later Mahayana Buddhism. Although the beginnings of Mahāyāna teachings go back to the 1st century there is little art and archaeological evidence to suggest that it became a mainstream cult for several centuries. In Mahayana it is not Gautama Buddha but the Bodhisattva who is important, including "deity" Bodhisattva like Manjushri and Tara, as well as aspects of the Buddha such as Aksobhya, and Amitabha. Except for a few Bodhisattva, these are not depicted at Ajanta, where the Buddha remains the dominant figure. Even the Bodhisattva images of Ajanta are never central objects of worship, but are always shown as attendants of the Buddha in the shrine. If a Bodhisattva is shown in isolation, as in the Astabhaya scenes, these were done in the very last years of activities at Ajanta, and are mostly 'intrusive' in nature, meaning that they were not planned by the original patrons, and were added by new donors after the original patrons had suddenly abandoned the region in the wake of Emperor Harisena's death.
The contrast between iconic and aniconic representations, that is, the stupa on one hand and the image of the Buddha on the other, is now being seen as a construct of the modern scholar rather than a reality of the past. The second phase of Ajanta shows that the stupa and image coincided together. If the entire corpus of the art of Ajanta including sculpture, iconography, architecture, epigraphy, and painting are analysed afresh it will become clear that there was no duality between the symbolic and human forms of the Buddha, as far as the 5th-century phase of Ajanta is concerned. That is why most current scholars tend to avoid the terms 'Hinayana' and 'Mahayana' in the context of Ajanta. They now prefer to call the second phase by the ruling dynasty, as the Vākāţaka phase.
CAVES
CAVE 1
Cave 1 was built on the eastern end of the horse-shoe shaped scarp, and is now the first cave the visitor encounters. This would when first made have been a less prominent position, right at the end of the row. According to Spink, it is one of the latest caves to have been excavated, when the best sites had been taken, and was never fully inaugurated for worship by the dedication of the Buddha image in the central shrine. This is shown by the absence of sooty deposits from butter lamps on the base of the shrine image, and the lack of damage to the paintings that would have been happened if the garland-hooks around the shrine had been in use for any period of time. Although there is no epigraphic evidence, Spink believes that the Vākāţaka Emperor Harishena was the benefactor of the work, and this is reflected in the emphasis on imagery of royalty in the cave, with those Jakata tales being selected that tell of those previous lives of the Buddha in which he was royal.
The cliff has a more steep slope here than at other caves, so to achieve a tall grand facade it was necessary to cut far back into the slope, giving a large courtyard in front of the facade. There was originally a columned portico in front of the present facade, which can be seen "half-intact in the 1880s" in pictures of the site, but this fell down completely and the remains, despite containing fine carving, were carelessly thrown down the slope into the river, from where they have been lost, presumably carried away in monsoon torrents.
This cave has one of the most elaborate carved façades, with relief sculptures on entablature and ridges, and most surfaces embellished with decorative carving. There are scenes carved from the life of the Buddha as well as a number of decorative motifs. A two pillared portico, visible in the 19th-century photographs, has since perished. The cave has a front-court with cells fronted by pillared vestibules on either side. These have a high plinth level. The cave has a porch with simple cells on both ends. The absence of pillared vestibules on the ends suggest that the porch was not excavated in the latest phase of Ajanta when pillared vestibules had become a necessity and norm. Most areas of the porch were once covered with murals, of which many fragments remain, especially on the ceiling. There are three doorways: a central doorway and two side doorways. Two square windows were carved between the doorways to brighten the interiors.
Each wall of the hall inside is nearly 12 m long and 6.1 m high. Twelve pillars make a square colonnade inside supporting the ceiling, and creating spacious aisles along the walls. There is a shrine carved on the rear wall to house an impressive seated image of the Buddha, his hands being in the dharmachakrapravartana mudra. There are four cells on each of the left, rear, and the right walls, though due to rock fault there are none at the ends of the rear aisle. The walls are covered with paintings in a fair state of preservation, though the full scheme was never completed. The scenes depicted are mostly didactic, devotional, and ornamental, with scenes from the Jataka stories of the Buddha's former existences as a bodhisattva), the life of the Gautama Buddha, and those of his veneration. The two most famous individual painted images at Ajanta are the two over-life size figures of the protective bodhisattvas Padmapani and Vajrapani on either side of the entrance to the Buddha shrine on the wall of the rear aisle (see illustrations above). According to Spink, the original dating of the paintings to about 625 arose largely or entirely because James Fegusson, a 19th-century architectural historian, had decided that a scene showing an ambassador being received, with figures in Persian dress, represented a recorded embassy to Persia (from a Hindu monarch at that) around that date.
CAVE 2
Cave 2, adjacent to Cave 1, is known for the paintings that have been preserved on its walls, ceilings, and pillars. It looks similar to Cave 1 and is in a better state of preservation.
Cave 2 has a porch quite different from Cave one. Even the façade carvings seem to be different. The cave is supported by robust pillars, ornamented with designs. The front porch consists of cells supported by pillared vestibules on both ends. The cells on the previously "wasted areas" were needed to meet the greater housing requirements in later years. Porch-end cells became a trend in all later Vakataka excavations. The simple single cells on porch-ends were converted into CPVs or were planned to provide more room, symmetry, and beauty.
The paintings on the ceilings and walls of this porch have been widely published. They depict the Jataka tales that are stories of the Buddha's life in former existences as Bodhisattva. Just as the stories illustrated in cave 1 emphasize kingship, those in cave 2 show many "noble and powerful" women in prominent roles, leading to suggestions that the patron was an unknown woman. The porch's rear wall has a doorway in the center, which allows entrance to the hall. On either side of the door is a square-shaped window to brighten the interior.
The hall has four colonnades which are supporting the ceiling and surrounding a square in the center of the hall. Each arm or colonnade of the square is parallel to the respective walls of the hall, making an aisle in between. The colonnades have rock-beams above and below them. The capitals are carved and painted with various decorative themes that include ornamental, human, animal, vegetative, and semi-divine forms.
Paintings appear on almost every surface of the cave except for the floor. At various places the art work has become eroded due to decay and human interference. Therefore, many areas of the painted walls, ceilings, and pillars are fragmentary. The painted narratives of the Jataka tales are depicted only on the walls, which demanded the special attention of the devotee. They are didactic in nature, meant to inform the community about the Buddha's teachings and life through successive rebirths. Their placement on the walls required the devotee to walk through the aisles and 'read' the narratives depicted in various episodes. The narrative episodes are depicted one after another although not in a linear order. Their identification has been a core area of research since the site's rediscovery in 1819. Dieter Schlingloff's identifications have updated our knowledge on the subject.
CAVE 4
The Archeological Survey of India board outside the caves gives the following detail about cave 4: "This is the largest monastery planned on a grandiose scale but was never finished. An inscription on the pedestal of the buddha's image mentions that it was a gift from a person named Mathura and paleographically belongs to 6th century A.D. It consists of a verandah, a hypostylar hall, sanctum with an antechamber and a series of unfinished cells. The rear wall of the verandah contains the panel of Litany of Avalokiteśvara".
The sanctuary houses a colossal image of the Buddha in preaching pose flanked by bodhisattvas and celestial nymphs hovering above.
CAVES 9-10
Caves 9 and 10 are the two chaitya halls from the first period of construction, though both were also undergoing an uncompleted reworking at the end of the second period. Cave 10 was perhaps originally of the 1st century BCE, and cave 9 about a hundred years later. The small "shrinelets" called caves 9A to 9D and 10A also date from the second period, and were commissioned by individuals.
The paintings in cave 10 include some surviving from the early period, many from an incomplete programme of modernization in the second period, and a very large number of smaller late intrusive images, nearly all Buddhas and many with donor inscriptions from individuals. These mostly avoided over-painting the "official" programme and after the best positions were used up are tucked away in less prominent positions not yet painted; the total of these (including those now lost) was probably over 300, and the hands of many different artists are visible.
OTHER CAVES
Cave 3 is merely a start of an excavation; according to Spink it was begun right at the end of the final period of work and soon abandoned. Caves 5 and 6 are viharas, the latter on two floors, that were late works of which only the lower floor of cave 6 was ever finished. The upper floor of cave 6 has many private votive sculptures, and a shrine Buddha, but is otherwise unfinished. Cave 7 has a grand facade with two porticos but, perhaps because of faults in the rock, which posed problems in many caves, was never taken very deep into the cliff, and consists only of the two porticos and a shrine room with antechamber, with no central hall. Some cells were fitted in.
Cave 8 was long thought to date to the first period of construction, but Spink sees it as perhaps the earliest cave from the second period, its shrine an "afterthought". The statue may have been loose rather than carved from the living rock, as it has now vanished. The cave was painted, but only traces remain.
SPINK´S DETAILED CHRONOLOGY
Walter M. Spink has over recent decades developed a very precise and circumstantial chronology for the second period of work on the site, which unlike earlier scholars, he places entirely in the 5th century. This is based on evidence such as the inscriptions and artistic style, combined with the many uncompleted elements of the caves. He believes the earlier group of caves, which like other scholars he dates only approximately, to the period "between 100 BCE – 100 CE", were at some later point completely abandoned and remained so "for over three centuries", as the local population had turned mainly Hindu. This changed with the accession of the Emperor Harishena of the Vakataka Dynasty, who reigned from 460 to his death in 477. Harisena extended the Central Indian Vakataka Empire to include a stretch of the east coast of India; the Gupta Empire ruled northern India at the same period, and the Pallava dynasty much of the south.
According to Spink, Harisena encouraged a group of associates, including his prime minister Varahadeva and Upendragupta, the sub-king in whose territory Ajanta was, to dig out new caves, which were individually commissioned, some containing inscriptions recording the donation. This activity began in 462 but was mostly suspended in 468 because of threats from the neighbouring Asmaka kings. Work continued on only caves 1, Harisena's own commission, and 17–20, commissioned by Upendragupta. In 472 the situation was such that work was suspended completely, in a period that Spink calls "the Hiatus", which lasted until about 475, by which time the Asmakas had replaced Upendragupta as the local rulers.
Work was then resumed, but again disrupted by Harisena's death in 477, soon after which major excavation ceased, except at cave 26, which the Asmakas were sponsoring themselves. The Asmakas launched a revolt against Harisena's son, which brought about the end of the Vakataka Dynasty. In the years 478–480 major excavation by important patrons was replaced by a rash of "intrusions" – statues added to existing caves, and small shrines dotted about where there was space between them. These were commissioned by less powerful individuals, some monks, who had not previously been able to make additions to the large excavations of the rulers and courtiers. They were added to the facades, the return sides of the entrances, and to walls inside the caves. According to Spink, "After 480, not a single image was ever made again at the site", and as Hinduism again dominated the region, the site was again abandoned, this time for over a millennium.
Spink does not use "circa" in his dates, but says that "one should allow a margin of error of one year or perhaps even two in all cases".
IMPACT ON MODERN INDIAN PAINTINGS
The Ajanta paintings, or more likely the general style they come from, influenced painting in Tibet and Sri Lanka.
The rediscovery of ancient Indian paintings at Ajanta provided Indian artists examples from ancient India to follow. Nandlal Bose experimented with techniques to follow the ancient style which allowed him to develop his unique style. Abanindranath Tagore also used the Ajanta paintings for inspiration.

Beamish, previously named 'Pit Hill', is a village in County Durham, England, situated to the north east of Stanley.
The entrance to Beamish Museum.
The village is contained within Hell Hole Wood and is home to Beamish Museum, an open-air museum seeking to replicate a northern town of the early 20th century. Its principal public house is the Shepherd and Shepherdess, near the Beamish Museum entrance.
To the south is the village of No Place (also called Co-operative Villas). North West Beamish lies in the conservation area of Beamish Burn.
Pockerley Manor
To the north of Beamish, Pockerley Manor preserves a rare though altered example of a pele tower in County Durham, probably dating from the 15th century with later alterations and additions. It is attached to a later farmhouse and the building is now known as Pockerley Manor. The tower has living accommodation built over a stone basement, the first floor reached through a stair built into the thickness of the wall, and the roof is largely original.
County Durham, officially simply Durham is a ceremonial county in North East England. The county borders Northumberland and Tyne and Wear to the north, the North Sea to the east, North Yorkshire to the south, and Cumbria to the west. The largest settlement is Darlington, and the county town is the city of Durham.
The county has an area of 2,721 km2 (1,051 sq mi) and a population of 866,846. The latter is concentrated in the east; the south-east is part of the Teesside built-up area, which extends into North Yorkshire. After Darlington (92,363), the largest settlements are Hartlepool (88,855), Stockton-on-Tees (82,729), and Durham (48,069). For local government purposes the county comprises three unitary authority areas—County Durham, Darlington, and Hartlepool—and part of a fourth, Stockton-on-Tees. The county historically included the part of Tyne and Wear south of the River Tyne, and excluded the part of County Durham south of the River Tees.
The west of the county contains part of the North Pennines uplands, a national landscape. The hills are the source of the rivers Tees and Wear, which flow east and form the valleys of Teesdale and Weardale respectively. The east of the county is flatter, and contains by rolling hills through which the two rivers meander; the Tees forms the boundary with North Yorkshire in its lower reaches, and the Wear exits the county near Chester-le-Street in the north-east. The county's coast is a site of special scientific interest characterised by tall limestone and dolomite cliffs.
What is now County Durham was on the border of Roman Britain, and contains survivals of this era at sites such as Binchester Roman Fort. In the Anglo-Saxon period the region was part of the Kingdom of Northumbria. In 995 the city of Durham was founded by monks seeking a place safe from Viking raids to house the relics of St Cuthbert. Durham Cathedral was rebuilt after the Norman Conquest, and together with Durham Castle is now a World Heritage Site. By the late Middle Ages the county was governed semi-independently by the bishops of Durham and was also a buffer zone between England and Scotland. County Durham became heavily industrialised in the nineteenth century, when many collieries opened on the Durham coalfield. The Stockton and Darlington Railway, the world's first public railway to use steam locomotives, opened in 1825. Most collieries closed during the last quarter of the twentieth century, but the county's coal mining heritage is remembered in the annual Durham Miners' Gala.
The history of County Durham.
Roman and pre-Roman
Remains of Prehistoric Durham include a number of Neolithic earthworks.
The Crawley Edge Cairns and Heathery Burn Cave are Bronze Age sites. Maiden Castle, Durham is an Iron Age site.
Brigantia, the land of the Brigantes, is said to have included what is now County Durham.
There are archaeological remains of Roman Durham. Dere Street and Cade's Road run through what is now County Durham. There were Roman forts at Concangis (Chester-le-Street), Lavatrae (Bowes), Longovicium (Lanchester), Piercebridge (Morbium), Vindomora (Ebchester) and Vinovium (Binchester). (The Roman fort at Arbeia (South Shields) is within the former boundaries of County Durham.) A Romanised farmstead has been excavated at Old Durham.
Anglo-Saxon
Anglian Kingdom of Bernicia
Around AD 547, an Angle named Ida founded the kingdom of Bernicia after spotting the defensive potential of a large rock at Bamburgh, upon which many a fortification was thenceforth built. Ida was able to forge, hold and consolidate the kingdom; although the native British tried to take back their land, the Angles triumphed and the kingdom endured.
Kingdom of Northumbria
In AD 604, Ida's grandson Æthelfrith forcibly merged Bernicia (ruled from Bamburgh) and Deira (ruled from York, which was known as Eforwic at the time) to create the Kingdom of Northumbria. In time, the realm was expanded, primarily through warfare and conquest; at its height, the kingdom stretched from the River Humber (from which the kingdom drew its name) to the Forth. Eventually, factional fighting and the rejuvenated strength of neighbouring kingdoms, most notably Mercia, led to Northumbria's decline. The arrival of the Vikings hastened this decline, and the Scandinavian raiders eventually claimed the Deiran part of the kingdom in AD 867 (which became Jórvík). The land that would become County Durham now sat on the border with the Great Heathen Army, a border which today still (albeit with some adjustments over the years) forms the boundaries between Yorkshire and County Durham.
Despite their success south of the river Tees, the Vikings never fully conquered the Bernician part of Northumbria, despite the many raids they had carried out on the kingdom. However, Viking control over the Danelaw, the central belt of Anglo-Saxon territory, resulted in Northumbria becoming isolated from the rest of Anglo-Saxon Britain. Scots invasions in the north pushed the kingdom's northern boundary back to the River Tweed, and the kingdom found itself reduced to a dependent earldom, its boundaries very close to those of modern-day Northumberland and County Durham. The kingdom was annexed into England in AD 954.
City of Durham founded
In AD 995, St Cuthbert's community, who had been transporting Cuthbert's remains around, partly in an attempt to avoid them falling into the hands of Viking raiders, settled at Dunholm (Durham) on a site that was defensively favourable due to the horseshoe-like path of the River Wear. St Cuthbert's remains were placed in a shrine in the White Church, which was originally a wooden structure but was eventually fortified into a stone building.
Once the City of Durham had been founded, the Bishops of Durham gradually acquired the lands that would become County Durham. Bishop Aldhun began this process by procuring land in the Tees and Wear valleys, including Norton, Stockton, Escomb and Aucklandshire in 1018. In 1031, King Canute gave Staindrop to the Bishops. This territory continued to expand, and was eventually given the status of a liberty. Under the control of the Bishops of Durham, the land had various names: the "Liberty of Durham", "Liberty of St Cuthbert's Land" "the lands of St Cuthbert between Tyne and Tees" or "the Liberty of Haliwerfolc" (holy Wear folk).
The bishops' special jurisdiction rested on claims that King Ecgfrith of Northumbria had granted a substantial territory to St Cuthbert on his election to the see of Lindisfarne in 684. In about 883 a cathedral housing the saint's remains was established at Chester-le-Street and Guthfrith, King of York granted the community of St Cuthbert the area between the Tyne and the Wear, before the community reached its final destination in 995, in Durham.
Following the Norman invasion, the administrative machinery of government extended only slowly into northern England. Northumberland's first recorded Sheriff was Gilebert from 1076 until 1080 and a 12th-century record records Durham regarded as within the shire. However the bishops disputed the authority of the sheriff of Northumberland and his officials, despite the second sheriff for example being the reputed slayer of Malcolm Canmore, King of Scots. The crown regarded Durham as falling within Northumberland until the late thirteenth century.
Norman and Anglo-Norman
Following the Battle of Hastings, William the Conqueror appointed Copsig as Earl of Northumbria, thereby bringing what would become County Durham under Copsig's control. Copsig was, just a few weeks later, killed in Newburn. Having already being previously offended by the appointment of a non-Northumbrian as Bishop of Durham in 1042, the people of the region became increasingly rebellious. In response, in January 1069, William despatched a large Norman army, under the command of Robert de Comines, to Durham City. The army, believed to consist of 700 cavalry (about one-third of the number of Norman knights who had participated in the Battle of Hastings), entered the city, whereupon they were attacked, and defeated, by a Northumbrian assault force. The Northumbrians wiped out the entire Norman army, including Comines, all except for one survivor, who was allowed to take the news of this defeat back.
Following the Norman slaughter at the hands of the Northumbrians, resistance to Norman rule spread throughout Northern England, including a similar uprising in York. William The Conqueror subsequently (and successfully) attempted to halt the northern rebellions by unleashing the notorious Harrying of the North (1069–1070). Because William's main focus during the harrying was on Yorkshire, County Durham was largely spared the Harrying.
Anglo-Norman Durham refers to the Anglo-Norman period, during which Durham Cathedral was built.
County Palatine of Durham
Matters regarding the bishopric of Durham came to a head in 1293 when the bishop and his steward failed to attend proceedings of quo warranto held by the justices of Northumberland. The bishop's case went before parliament, where he stated that Durham lay outside the bounds of any English shire and that "from time immemorial it had been widely known that the sheriff of Northumberland was not sheriff of Durham nor entered within that liberty as sheriff. . . nor made there proclamations or attachments".[16] The arguments appear to have prevailed, as by the fourteenth century Durham was accepted as a liberty which received royal mandates direct. In effect it was a private shire, with the bishop appointing his own sheriff. The area eventually became known as the "County Palatine of Durham".
Sadberge was a liberty, sometimes referred to as a county, within Northumberland. In 1189 it was purchased for the see but continued with a separate sheriff, coroner and court of pleas. In the 14th century Sadberge was included in Stockton ward and was itself divided into two wards. The division into the four wards of Chester-le-Street, Darlington, Easington and Stockton existed in the 13th century, each ward having its own coroner and a three-weekly court corresponding to the hundred court. The diocese was divided into the archdeaconries of Durham and Northumberland. The former is mentioned in 1072, and in 1291 included the deaneries of Chester-le-Street, Auckland, Lanchester and Darlington.
The term palatinus is applied to the bishop in 1293, and from the 13th century onwards the bishops frequently claimed the same rights in their lands as the king enjoyed in his kingdom.
Early administration
Boundaries, exclaves and population
The historic boundaries of County Durham included a main body covering the catchment of the Pennines in the west, the River Tees in the south, the North Sea in the east and the Rivers Tyne and Derwent in the north. The county palatinate also had a number of liberties: the Bedlingtonshire, Islandshire and Norhamshire exclaves within Northumberland, and the Craikshire exclave within the North Riding of Yorkshire. In 1831 the county covered an area of 679,530 acres (2,750.0 km2) and had a population of 253,910. These exclaves were included as part of the county for parliamentary electoral purposes until 1832, and for judicial and local-government purposes until the coming into force of the Counties (Detached Parts) Act 1844, which merged most remaining exclaves with their surrounding county. The boundaries of the county proper remained in use for administrative and ceremonial purposes until the Local Government Act 1972.
Survey
Boldon Book (1183 or 1184) is a polyptichum for the Bishopric of Durham.
Palatinate
Until the 15th century, the most important administrative officer in the Palatinate was the steward. Other officers included the sheriff, the coroners, the Chamberlain and the chancellor. The palatine exchequer originated in the 12th century. The palatine assembly represented the whole county, and dealt chiefly with fiscal questions. The bishop's council, consisting of the clergy, the sheriff and the barons, regulated judicial affairs, and later produced the Chancery and the courts of Admiralty and Marshalsea.
The prior of Durham ranked first among the bishop's barons. He had his own court, and almost exclusive jurisdiction over his men. A UNESCO site describes the role of the Prince-Bishops in Durham, the "buffer state between England and Scotland":
From 1075, the Bishop of Durham became a Prince-Bishop, with the right to raise an army, mint his own coins, and levy taxes. As long as he remained loyal to the king of England, he could govern as a virtually autonomous ruler, reaping the revenue from his territory, but also remaining mindful of his role of protecting England’s northern frontier.
A report states that the Bishops also had the authority to appoint judges and barons and to offer pardons.
There were ten palatinate barons in the 12th century, most importantly the Hyltons of Hylton Castle, the Bulmers of Brancepeth, the Conyers of Sockburne, the Hansards of Evenwood, and the Lumleys of Lumley Castle. The Nevilles owned large estates in the county. John Neville, 3rd Baron Neville de Raby rebuilt Raby Castle, their principal seat, in 1377.
Edward I's quo warranto proceedings of 1293 showed twelve lords enjoying more or less extensive franchises under the bishop. The repeated efforts of the Crown to check the powers of the palatinate bishops culminated in 1536 in the Act of Resumption, which deprived the bishop of the power to pardon offences against the law or to appoint judicial officers. Moreover, indictments and legal processes were in future to run in the name of the king, and offences to be described as against the peace of the king, rather than that of the bishop. In 1596 restrictions were imposed on the powers of the chancery, and in 1646 the palatinate was formally abolished. It was revived, however, after the Restoration, and continued with much the same power until 5 July 1836, when the Durham (County Palatine) Act 1836 provided that the palatine jurisdiction should in future be vested in the Crown.
Wars
During the 15th-century Wars of the Roses, Henry VI passed through Durham. On the outbreak of the Great Rebellion in 1642 Durham inclined to support the cause of Parliament, and in 1640 the high sheriff of the palatinate guaranteed to supply the Scottish army with provisions during their stay in the county. In 1642 the Earl of Newcastle formed the western counties into an association for the King's service, but in 1644 the palatinate was again overrun by a Scottish army, and after the Battle of Marston Moor (2 July 1644) fell entirely into the hands of Parliament.
Parliamentary representation and secular powers
In 1614, a Bill was introduced in Parliament for securing representation to the county and city of Durham and the borough of Barnard Castle. The bishop strongly opposed the proposal as an infringement of his palatinate rights, and the county was first summoned to return members to Parliament in 1654. After the Restoration of 1660 the county and city returned two members each. In the wake of the Reform Act of 1832 the county returned two members for two divisions, and the boroughs of Gateshead, South Shields and Sunderland acquired representation. The bishops lost their secular powers in 1836. The boroughs of Darlington, Stockton and Hartlepool returned one member each from 1868 until the Redistribution of Seats Act 1885.
Later government
The Municipal Corporations Act 1835 reformed the municipal boroughs of Durham, Stockton on Tees and Sunderland. In 1875, Jarrow was incorporated as a municipal borough, as was West Hartlepool in 1887. At a county level, the Local Government Act 1888 reorganised local government throughout England and Wales. Most of the county came under control of the newly formed Durham County Council in an area known as an administrative county. Not included were the county boroughs of Gateshead, South Shields and Sunderland. However, for purposes other than local government, the administrative county of Durham and the county boroughs continued to form a single county to which the Crown appointed a Lord Lieutenant of Durham.
Over its existence, the administrative county lost territory, both to the existing county boroughs, and because two municipal boroughs became county boroughs: West Hartlepool in 1902 and Darlington in 1915. The county boundary with the North Riding of Yorkshire was adjusted in 1967: that part of the town of Barnard Castle historically in Yorkshire was added to County Durham, while the administrative county ceded the portion of the Borough of Stockton-on-Tees in Durham to the North Riding. In 1968, following the recommendation of the Local Government Commission, Billingham was transferred to the County Borough of Teesside, in the North Riding. In 1971, the population of the county—including all associated county boroughs (an area of 2,570 km2 (990 sq mi)—was 1,409,633, with a population outside the county boroughs of 814,396.
In 1974, the Local Government Act 1972 abolished the administrative county and the county boroughs, reconstituting County Durham as a non-metropolitan county. The reconstituted County Durham lost territory to the north-east (around Gateshead, South Shields and Sunderland) to Tyne and Wear and to the south-east (around Hartlepool) to Cleveland. At the same time it gained the former area of Startforth Rural District from the North Riding of Yorkshire. The area of the Lord Lieutenancy of Durham was also adjusted by the Act to coincide with the non-metropolitan county (which occupied 3,019 km2 (1,166 sq mi) in 1981).
In 1996, as part of 1990s UK local government reform by Lieutenancies Act 1997, Cleveland was abolished. Its districts were reconstituted as unitary authorities. Hartlepool and Stockton-on-Tees (north Tees) were returned to the county for the purposes of Lord Lieutenancy. Darlington also became a third unitary authority of the county. The Royal Mail abandoned the use of postal counties altogether, permitted but not mandatory being at a writer wishes.
As part of the 2009 structural changes to local government in England initiated by the Department for Communities and Local Government, the seven district councils within the County Council area were abolished. The County Council assumed their functions and became the fourth unitary authority. Changes came into effect on 1 April 2009.
On 15 April 2014, North East Combined Authority was established under the Local Democracy, Economic Development and Construction Act 2009 with powers over economic development and regeneration. In November 2018, Newcastle City Council, North Tyneside Borough Council, and Northumberland County Council left the authority. These later formed the North of Tyne Combined Authority.
In May 2021, four parish councils of the villages of Elwick, Hart, Dalton Piercy and Greatham all issued individual votes of no confidence in Hartlepool Borough Council, and expressed their desire to join the County Durham district.
In October 2021, County Durham was shortlisted for the UK City of Culture 2025. In May 2022, it lost to Bradford.
Eighteenth century
Eighteenth century Durham saw the appearance of dissent in the county and the Durham Ox. The county did not assist the Jacobite Rebellion of 1715. The Statue of Neptune in the City of Durham was erected in 1729.
Nineteenth century
A number of disasters happened in Nineteenth century Durham. The Felling mine disasters happened in 1812, 1813, 1821 and 1847. The Philadelphia train accident happened in 1815. In 1854, there was a great fire in Gateshead. One of the West Stanley Pit disasters happened in 1882. The Victoria Hall disaster happened in 1883.
Twentieth century
One of the West Stanley Pit disasters happened in 1909. The Darlington rail crash happened in 1928. The Battle of Stockton happened in 1933. The Browney rail crash happened in 1946.
Political history
The First Treaty of Durham was made at Durham in 1136. The Second Treaty of Durham was made at Durham in 1139.
Military and naval history
The county regiment was the Durham Light Infantry, which replaced, in particular, the 68th (Durham) Regiment of Foot (Light Infantry) and the Militia and Volunteers of County Durham.
RAF Greatham, RAF Middleton St George and RAF Usworth were located in County Durham.
David I, the King of Scotland, invaded the county in 1136, and ravaged much of the county 1138. In 17 October 1346, the Battle of Neville's Cross was fought at Neville's Cross, near the city of Durham. On 16 December 1914, during the First World War, there was a raid on Hartlepool by the Imperial German Navy.
County Durham has long been associated with coal mining, from medieval times up to the late 20th century. The Durham Coalfield covered a large area of the county, from Bishop Auckland, to Consett, to the River Tyne and below the North Sea, thereby providing a significant expanse of territory from which this rich mineral resource could be extracted.
King Stephen possessed a mine in Durham, which he granted to Bishop Pudsey, and in the same century colliers are mentioned at Coundon, Bishopwearmouth and Sedgefield. Cockfield Fell was one of the earliest Landsale collieries in Durham. Edward III issued an order allowing coal dug at Newcastle to be taken across the Tyne, and Richard II granted to the inhabitants of Durham licence to export the produce of the mines, without paying dues to the corporation of Newcastle. The majority was transported from the Port of Sunderland complex, which was constructed in the 1850s.
Among other early industries, lead-mining was carried on in the western part of the county, and mustard was extensively cultivated. Gateshead had a considerable tanning trade and shipbuilding was undertaken at Jarrow, and at Sunderland, which became the largest shipbuilding town in the world – constructing a third of Britain's tonnage.[citation needed]
The county's modern-era economic history was facilitated significantly by the growth of the mining industry during the nineteenth century. At the industry's height, in the early 20th century, over 170,000 coal miners were employed, and they mined 58,700,000 tons of coal in 1913 alone. As a result, a large number of colliery villages were built throughout the county as the industrial revolution gathered pace.
The railway industry was also a major employer during the industrial revolution, with railways being built throughout the county, such as The Tanfield Railway, The Clarence Railway and The Stockton and Darlington Railway. The growth of this industry occurred alongside the coal industry, as the railways provided a fast, efficient means to move coal from the mines to the ports and provided the fuel for the locomotives. The great railway pioneers Timothy Hackworth, Edward Pease, George Stephenson and Robert Stephenson were all actively involved with developing the railways in tandem with County Durham's coal mining industry. Shildon and Darlington became thriving 'railway towns' and experienced significant growths in population and prosperity; before the railways, just over 100 people lived in Shildon but, by the 1890s, the town was home to around 8,000 people, with Shildon Shops employing almost 3000 people at its height.
However, by the 1930s, the coal mining industry began to diminish and, by the mid-twentieth century, the pits were closing at an increasing rate. In 1951, the Durham County Development Plan highlighted a number of colliery villages, such as Blackhouse, as 'Category D' settlements, in which future development would be prohibited, property would be acquired and demolished, and the population moved to new housing, such as that being built in Newton Aycliffe. Likewise, the railway industry also began to decline, and was significantly brought to a fraction of its former self by the Beeching cuts in the 1960s. Darlington Works closed in 1966 and Shildon Shops followed suit in 1984. The county's last deep mines, at Easington, Vane Tempest, Wearmouth and Westoe, closed in 1993.
Post markings
Postal Rates from 1801 were charged depending on the distance from London. Durham was allocated the code 263 the approximate mileage from London. From about 1811, a datestamp appeared on letters showing the date the letter was posted. In 1844 a new system was introduced and Durham was allocated the code 267. This system was replaced in 1840 when the first postage stamps were introduced.
Antiquities
According to the Encyclopædia Britannica Eleventh Edition (1911): "To the Anglo-Saxon period are to be referred portions of the churches of Monk Wearmouth (Sunderland), Jarrow, Escomb near Bishop Auckland, and numerous sculptured crosses, two of which are in situ at Aycliffe. . . . The Decorated and Perpendicular periods are very scantily represented, on account, as is supposed, of the incessant wars between England and Scotland in the 14th and 15th centuries. The principal monastic remains, besides those surrounding Durham cathedral, are those of its subordinate house or "cell," Finchale Priory, beautifully situated by the Wear. The most interesting castles are those of Durham, Raby, Brancepeth and Barnard. There are ruins of castelets or peel-towers at Dalden, Ludworth and Langley Dale. The hospitals of Sherburn, Greatham and Kepyer, founded by early bishops of Durham, retain but few ancient features."
The best remains of the Norman period include Durham Cathedral and Durham Castle, and several parish churches, such as St Laurence Church in Pittington. The Early English period has left the eastern portion of the cathedral, the churches of Darlington, Hartlepool, and St Andrew, Auckland, Sedgefield, and portions of a few other churches.
'Durham Castle and Cathedral' is a designated UNESCO World Heritage Site. Elsewhere in the County there is Auckland Castle.
