London

Charles Saatchi's gallery, which opened after numerous delays in October 2008, has three floors, providing more than 70,000sq ft of space for temporary exhibitions. Given his fame as a promoter in the 1990s of what became known as the Young British Artists - Damien Hirst, Tracey Emin, Gavin Turk, Sarah Lucas et al - it surprised many that the opening exhibition was of new Chinese art. Since then Saatchi Gallery - housed in the historically significant Duke of York HQ - has continued its mission to provide a platform for unknown, young, contemporary artists both homegrown and international.
