Charles Saatchi, who made his fortune in advertising, is one of Britain's most highly regarded collectors of contemporary art, credited with popularizing the Young British Artists movement through his championing of early works by the likes of Damien Hirst and Tracey Emin. The museum's home—its third in ten years—is at the former Duke of York's HQ, just off King's Road. Built in 1803, its grand period exterior belies its imaginatively restored modern interior, which
was transformed into 14 gallery exhibition spaces of varying size and shape. Unlike Tate Modern, there is no permanent collection beyond an ongoing site-specific installation; instead, at any one time the galleries are given over to between one and three exhibitions that normally run for up to six months. There's also an excellent café, which is open late.
