London is the capital and most populous city of England and the United Kingdom. Standing on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core. The bulk of this conurbation forms the Greater London administrative area (coterminous with the London region), governed by the Mayor of London and the London Assembly.
London contains four World Heritage Sites: the Tower of London; Kew Gardens; the site comprising the Palace of Westminster, Westminster Abbey, and St Margaret's Church; and the historic settlement of Greenwich (in which the Royal Observatory, Greenwich marks the Prime Meridian, 0° longitude, and GMT). Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Paul's Cathedral, Tower Bridge, Trafalgar Square, and The Shard. London is home to numerous museums, galleries, libraries, sporting events and other cultural institutions, including the British Museum, National Gallery, Tate Modern, British Library and 40 West End theatres. The London Underground is the oldest underground railway network in the world.
Status
Within London, both the City of London and the City of Westminster have city status and both the City of London and the remainder of Greater London are the ceremonial counties.The area of Greater London has incorporated areas that were once part of the historic counties of Middlesex, Kent, Surrey, Essex and Hertfordshire. London's status as the capital of England, and later the United Kingdom, has never been granted or confirmed officially—by statute or in written form.
Its position was formed through constitutional convention, making its status as de facto capital a part of the UK's unwritten constitution. The capital of England was moved to London from Winchester as the Palace of Westminster developed in the 12th and 13th centuries to become the permanent location of the royal court, and thus the political capital of the nation. More recently, Greater London has been defined as a region of England and in this context is known as London.
Tourism
London is a popular centre for tourism, one of its prime industries, employing the equivalent of 350,000 full-time workers in 2003, while annual expenditure by tourists is around £15 billion. London attracts over 14 million international visitors per year, making it Europe's most visited city. London attracts 27 million overnight-stay visitors every year.
