The Tate Gallery was founded as the National Gallery of British Art in 1897. It became popularly known as the 'Tate Gallery' after Sir Henry Tate, whose collection of paintings formed the core of the gallery exhibits. The original building was erected on the site of the Millbank Penitentiary. The gallery originally featured modern British art, but in 1911 the remit was changed to include British art since 1500. The gallery was later split into several divisions, with Tate Britain and Tate Modern in London, and other branches in St Ives and Liverpool.
