Tate Modern is Britain's national museum of international modern art in London and is, with Tate Britain, Tate Liverpool, Tate St Ives, and Tate Online, part of Tate. Since the museum's opening on 12 May 2000, it has become a very popular destination for Londoners and tourists. Entry to collection displays and some temporary exhibitions is free.

The permanent collection of Tate Modern is on display on levels three and five of the building, while level four houses large temporary exhibitions and a small exhibition space on level 2 houses work by contemporary artists. The Turbine Hall (level 1), which once housed the electricity generators of the old power station, is seven storeys tall with 3,400 square metres of floorspace.
