"Once collectively known singularly as the Tate Gallery, London now has two Tate art galleries: Tate Britain and Tate Modern. Comprising one of the world's most important art collections, the original gallery opened in 1897 as the basis of a national collection of significant British art, and continued to make acquisitions, needing more space to properly display its collections. The end result was the establishment of Tate Britain, in Millbank on the north side of the Thames, as home to its permanent collection of historic British paintings."
