Nightscape of Barcelona 06, Spain

is a city on the northeastern coast of Spain. It is the capital and largest city of the autonomous community of Catalonia, as well as the second-most populous municipality of Spain. With a population of 1.6 million within city limits, its urban area extends to numerous neighbouring municipalities within the province of Barcelona and is home to around 5.3 million people, making it the fifth most populous urban area of the European Union after Paris, the Ruhr area, Madrid and Milan. It is one of the largest metropolises on the Mediterranean Sea, located on the coast between the mouths of the rivers Llobregat and Besòs, bounded to the west by the Serra de Collserola mountain range.

Founded as a Roman city, in the Middle Ages Barcelona became the capital of the County of Barcelona. After joining with the Kingdom of Aragon to form the confederation of the Crown of Aragon, Barcelona, which continued to be the capital of the Principality of Catalonia, became the most important city in the Crown of Aragon and the main economic and administrative centre of the Crown, only to be overtaken by Valencia, wrested from Moorish control by the Catalans, shortly before the dynastic union between the Crown of Castile and the Crown of Aragon in 1492. Barcelona became the centre of Catalan separatism, briefly becoming part of France during the 17th century Reapers' War and again in 1812 until 1814 under Napoleon. It was the capital of Revolutionary Catalonia during the Spanish Revolution of 1936, and the seat of government of the Second Spanish Republic later in the Spanish Civil War, until its capture by the fascists in 1939. After the Spanish transition to democracy in the 1970s, Barcelona once again became the capital of an autonomous Catalonia.

Barcelona has a rich cultural heritage and is today an important cultural centre and a major tourist destination. Particularly renowned are the architectural works of Antoni Gaudí and Lluís Domènech i Montaner, which have been designated UNESCO World Heritage Sites. The city is home to two of the most prestigious universities in Spain: the University of Barcelona and Pompeu Fabra University. The headquarters of the Union for the Mediterranean are located in Barcelona. The city is known for hosting the 1992 Summer Olympics as well as world-class conferences and expositions. In addition, many international sport tournaments have been played here.

Barcelona is a major cultural, economic, and financial centre in southwestern Europe, as well as the main biotech hub in Spain. As a leading world city, Barcelona's influence in global socio-economic affairs qualifies it for global city status (Beta +).

Barcelona is a transport hub, with the Port of Barcelona being one of Europe's principal seaports and busiest European passenger port, an international airport, Barcelona–El Prat Airport, which handles over 50 million passengers per year, an extensive motorway network, and a high-speed rail line with a link to France and the rest of Europe.

The name Barcelona comes from the ancient Iberian Baŕkeno, attested in an ancient coin inscription found on the right side of the coin in Iberian script as Barkeno in Levantine Iberian script, in ancient Greek sources as Βαρκινών, Barkinṓn; and in Latin as Barcino, Barcilonum and Barcenona.

Some older sources suggest that the city may have been named after the Carthaginian general Hamilcar Barca, who was supposed to have founded the city in the 3rd century BC, but there is no evidence that Barcelona was ever a Carthaginian settlement, or that its name in antiquity, Barcino, had any connection with the Barcid family of Hamilcar. During the Middle Ages, the city was variously known as Barchinona, Barçalona, Barchelonaa, and Barchenona.

An abbreviated form sometimes used by locals for the city is Barna. Barça is only applied to the local football club FC Barcelona, not to the city. Another common abbreviation is 'BCN', which is also the IATA airport code of the Barcelona-El Prat Airport. The origin of the earliest settlement at the site of present-day Barcelona is unclear. The ruins of an early settlement have been found, including different tombs and dwellings dating to earlier than 5000 BC. The founding of Barcelona is the subject of two different legends. The first attributes the founding of the city to the mythological Hercules. The second legend attributes the foundation of the city directly to the historical Carthaginian general, Hamilcar Barca, father of Hannibal, who supposedly named the city Barcino after his family in the 3rd century BC, but there is no historical or linguistic evidence that this is true. Archeological evidence in the form of coins from the 3rd century BC have been found on the hills at the foot of Montjuïc with the name Bárkeno written in an ancient script in the Iberian language[citation needed]. Thus, we can conclude[clarification needed] that the Laietani[citation needed], an ancient Iberian (pre-Roman) people of the Iberian peninsula, who inhabited the area occupied by the city of Barcelona around 3–2 BC[clarification needed], called the area Bàrkeno, which means "The Place of the Plains" (Barrke = plains/terrace).

The marriage of Ferdinand II of Aragon and Isabella I of Castile in 1469 united the two royal lines. Madrid became the centre of political power whilst the colonization of the Americas reduced the financial importance (at least in relative terms) of Mediterranean trade. Barcelona was a centre of Catalan separatism, including the Catalan Revolt (1640–52) against Philip IV of Spain. The great plague of 1650–1654 halved the city's population.

In the 18th century, a fortress was built at Montjuïc that overlooked the harbour. In 1794, this fortress was used by the French astronomer Pierre François André Méchain for observations relating to a survey stretching to Dunkirk that provided the official basis of the measurement of a metre. The definitive metre bar, manufactured from platinum, was presented to the French legislative assembly on 22 June 1799. Much of Barcelona was negatively affected by the Napoleonic wars, but the start of industrialization saw the fortunes of the province improve.

In the mid-1850s, Barcelona was struggling with population density as it became an industrial, port city and European capital. The city's density was at 856 people per hectare, more than double that of Paris. Mortality rates were on the rise and any outbreaks of disease would devastate the population. To solve the issue, a civil engineer named Ildefons Cerdà proposed a plan for a new district known as the Eixample. The citizens of Barcelona had begun to demolish the medieval wall surrounding and constricting the city. Cerdà thought it best to transform the land outside the walls into an area characterized by a scientific approach to urbanization. His proposal consisted of a grid of streets to unite the old city and surrounding villages. There would also be wide streets to allow people to breathe clean air, gardens in the centre of each street block, integration of rich and poor giving both groups access to the same services, and smooth-flowing traffic. Urban quality, egalitarianism, hygiene, sunlight, and efficiency were all major keys for Cerdà's vision. Not everything he imagined would be realized within the Eixample district, but the iconic octagonal superblocks with chamfered corners for better visibility are his direct brainchild and remain immensely helpful even 170 years later. The district and its ideals were not appreciated at the time. The city council awarded the design of the extension plan to another architect. The Spanish government was the one to step in and impose Cerdà's plan, laying the groundwork for many more tensions between the Spanish and Catalan administrations. Regardless, some of the upper class citizens of Barcelona were excited by the new plan and began a race to build "the biggest, tallest, most attractive house" in the district. Their interest and money fueled the rich diversity that we now see in the district's architecture. In the end, Cerdà's ideas would have a lasting impact on Barcelona's development, earning it international recognition for its highly efficient approach to urban planning and design.

The death of Franco in 1975 brought on a period of democratization throughout Spain. Pressure for change was particularly strong in Barcelona, which considered that it had been punished during nearly forty years of Francoism for its support of the Republican government. Massive, but peaceful, demonstrations on 11 September 1977 assembled over a million people in the streets of Barcelona to call for the restoration of Catalan autonomy. It was granted less than a month later.

The development of Barcelona was promoted by two events in 1986: Spanish accession to the European Community, and particularly Barcelona's designation as host city of the 1992 Summer Olympics. The process of urban regeneration has been rapid, and accompanied by a greatly increased international reputation of the city as a tourist destination. The increased cost of housing has led to a slight decline (−16.6%) in the population over the last two decades of the 20th century as many families move out into the suburbs. This decline has been reversed since 2001, as a new wave of immigration (particularly from Latin America and from Morocco) has gathered pace.

In 1987, an ETA car bombing at Hipercor killed 21 people. On 17 August 2017, a van was driven into pedestrians on La Rambla, killing 14 and injuring at least 100, one of whom later died. Other attacks took place elsewhere in Catalonia. The Prime Minister of Spain, Mariano Rajoy, called the attack in Barcelona a jihadist attack. Amaq News Agency attributed indirect responsibility for the attack to the Islamic State of Iraq and the Levant (ISIL). During the 2010s, Barcelona became the focus city[citation needed] for the ongoing Catalan independence movement, its consequent standoff between the regional and national government and later protests.

In July 2023, Barcelona was announced as the UNESCO-UIA World Capital of Architecture for the 2024–2026 term. This means it will be the hub for discussion around global challenges including culture, heritage, urban planning and architecture. In addition to being the capital through 2026, it will also host the UIA World Congress of Architects for that year. The honour is befitting of Barcelona, as its history is peppered with architectural achievement and various iconic styles and influences. From its ancient Roman roots, to the Gothic and Modernisme movements, Barcelona has thrived through the way it ties together architecture and culture.

Barcelona is located on the northeast coast of the Iberian Peninsula, facing the Mediterranean Sea, on a plain approximately 5 km (3 mi) wide limited by the mountain range of Collserola, the Llobregat river to the southwest and the Besòs river to the north. This plain covers an area of 170 km2 (66 sq mi), of which 101 km2 (39.0 sq mi) are occupied by the city itself. It is 120 km (75 mi) south of the Pyrenees and the Catalan border with France.

Tibidabo, 512 m (1,680 ft) high, offers striking views over the city and is topped by the 288.4 m (946.2 ft) Torre de Collserola, a telecommunications tower that is visible from most of the city. Barcelona is peppered with small hills, most of them urbanized, that gave their name to the neighbourhoods built upon them, such as Carmel (267 m or 876 ft), Putget (es) (181 m or 594 ft) and Rovira (261 m or 856 ft). The escarpment of Montjuïc (173 m or 568 ft), situated to the southeast, overlooks the harbour and is topped by Montjuïc Castle, a fortress built in the 17–18th centuries to control the city as a replacement for the Ciutadella. Today, the fortress is a museum and Montjuïc is home to several sporting and cultural venues, as well as Barcelona's biggest park and gardens.

The city borders on the municipalities of Santa Coloma de Gramenet and Sant Adrià de Besòs to the north; the Mediterranean Sea to the east; El Prat de Llobregat and L'Hospitalet de Llobregat to the south; and Sant Feliu de Llobregat, Sant Just Desvern, Esplugues de Llobregat, Sant Cugat del Vallès, and Montcada i Reixac to the west. The municipality includes two small sparsely-inhabited exclaves to the north-west.
