Tate Modern is the national gallery of international modern art, created in the year 2000 from a disused power station in the heart of London. Tate Modern includes modern British art where it contributes to the story of modern art, so major modern British artists may be found at both Tate Modern and Tate Britain. Tate Modern's displays consist of four wings located on Levels 3 and 5. At the heart of each wing is a large central display, or ‘hub’, which focuses on a key period in the development of twentieth-century art. These four seminal periods are Surrealism, Minimalism, Post-war innovations in abstraction and figuration, and the three linked movements Cubism, Futurism and Vorticism. Around these ‘hubs’ a diverse range of related displays present works which anticipated, challenged or responded to these four major movements. Moving back and forwards in time, these displays reflect the ongoing dialogue between past and present and suggest contemporary perspectives for approaching and reassessing the past. Tate Modern is open to the public every day of the year except 24, 25 and 26 December. Admission is free except for major exhibitions. If you wish to see a particular work of art, please check it is on display first.
