Tate Britain, known from 1897 to 1932 as the National Gallery of British Art and from 1932 to 2000 as the Tate Gallery, is an art museum on Millbank in the City of Westminster in London. It is part of the Tate network of galleries in England, with Tate Modern, Tate Liverpool and Tate St Ives. It is the oldest gallery in the network, having opened in 1897. It houses a substantial collection of the art of the United Kingdom since Tudor times, and in particular has large holdings of the works of J. M. W. Turner, who bequeathed all his own collection to the nation. It is one of the largest museums in the country.
