London, south-east of Britain, is the capital and largest city of the United Kingdom. Long time the capital of the British Empire, it is henceforth the political center and the seat of the Commonwealth.
Founded almost 2000 years ago by the Romans under the name Londinium, London in the nineteenth century was the most populous city in the world. Now widely exceeded by many megacities, it remains a city of the first rank, because of its reach and its considerable economic power, mainly due to its status as the first global financial center.
In the London area, composed of the Inner London and Outer London, there were 8,416,535 residents in 2013, and it produced a fifth of gross domestic product in the United Kingdom. In 2012, the urban area of London had 8,416,535 inhabitants, its agglomeration 11,140,445 and its metropolitan area (larger urban zone or area of direct influence) 12,317,800 inhabitants. In Europe, only the agglomerations Moscow, Istanbul and Paris have a comparable demographic weight. Its inhabitants call themselves Londoners.
London, the only city to have hosted the Olympics three times (1908, 1948, 2012), is dynamic and very diverse culturally. It plays an important role in art and fashion. It receives 28 million tourists per year and has four sites in World heritage and numerous iconic landmarks: the Palace of Westminster, Tower Bridge, Tower of London, Westminster Abbey, Buckingham Palace, and renowned institutions like the British Museum or the National Gallery.
