Set in a former power station by the Thames, from the outside it looks just like your ordinary power plant. The interior, however, has been reinvented to accommodate Britain's collection of international modern art. With an ever expanding acquisition programme, the works range from 1900 to the present day. The Turbine Hall, a massive five-story high room holds large, specially-comissioned works by contemporary artists. A large performance space, the tanks (three connecting, underground former oil tanks), an auditorium, an eduction centre, a café and a community garden are all part of this massive, seven-floor cultural venue. Admission is free of charge. The Tate boat connects the Tate Modern to the Tate London across the river and runs every 40 minutes.
