Situated adjacent to the new Globe Theatre on the South Bank, Tate Modern is the national repository for international modern art in the capital. The gallery, which is linked to St Paul's Cathedral by the Millennium Bridge, was converted to its present form by the Swiss architects Herzog & de Meuron from the former Bankside Power Station.
The striking architecture of the building is reminiscent of one its original designer's other works; as well as Bankside, Sir Giles Englebert Scott also designed Battersea Power Station and the classic red phone box.
The building contains three floors' worth of galleries as well as its imposing turbine hall, fully four storeys high, which is used for some of Tate Modern's more sizeable exhibits.
Contemporary artists have been specially commissioned to produce a piece for the hall for the last five years (since the gallery opened) and this looks set to continue.
