Arts, Museums and Cultural Institutions
London's national museums and galleries are, with the exception of some special exhibitions, free to enter, which means that the British Museum, the Natural History Museum, the Victoria and Albert Museum, the National Gallery, the Tate Modern, the National Portrait Gallery, and the Science Museum are accessible to everyone on every visit. The British Museum holds one of the largest and most comprehensive collections of human history and culture ever assembled, including objects of such significance and such contested ownership that the question of their repatriation is one of the defining international cultural debates of the current era. The Tate Modern, in the converted Bankside Power Station, is the most visited modern art gallery in the world. The Barbican Center, the Royal Festival Hall, the Royal Opera House, and the Southbank Center between them program the most diverse and extensive performing arts calendar of any city in Europe.
