Tate Modern is the national museum for international modern art from 1900 till today. It is part of the family of 4 Tate museums, all of which exhibit part of the Tate collection. The museum has been housed since 2000 in a disused power station on the Thames. The Tate Boat maintains a regular service in between Tate Britain, the London Eye and Tate Modern.
Like most museums in London, this museum is also free of charge.
