London -- View from Tate Modern
London (/ˈlʌndən/) is the capital city of England and the United Kingdom, the largest metropolitan area in the United Kingdom and the largest urban zone in the European Union by most measures. Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who called it Londinium. London's ancient core, the City of London, largely retains its square-mile medieval boundaries. Since at least the 19th century the name London has also referred to the metropolis developed around this core. The bulk of this conurbation forms the London region and the Greater London administrative area, governed by the elected Mayor of London and the London Assembly.
Tate Modern is a modern art gallery located in London, England. It is Britain's national gallery of international modern art and forms part of the Tate group (together with Tate Britain, Tate Liverpool, Tate St Ives and Tate Online). It is the most-visited modern art gallery in the world, with around 4.7 million visitors per year. It is based in the former Bankside Power Station, in the Bankside area of Central London.
