Tate Modern is a modern art gallery located in London. 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 based in the former Bankside Power Station, in the Bankside area of the London Borough of Southwark. Tate holds the national collection of British art from 1900 to the present day and international modern and contemporary art. Tate Modern is one of the largest museums of modern and contemporary art in the world. As with the UK’s other national galleries and museums, there is no admission charge for access to the collection displays, which take up the majority of the gallery space, while tickets must be purchased for the major temporary exhibitions.
