A contemporary-art engine rather than a static collection, Saatchi Gallery turns fifteen airy white-cube rooms into a rolling conversation about now. Housed since 2008 in the Grade II* Duke of York's HQ off King's Road, it specialises in museum-scale temporary shows-from global surveys to pop-culture blockbusters-alongside photography prizes and film installations that give new voices real space. Expect clean sightlines, big gestures and curators who prize clarity over jargon. Start with the largest ground-floor gallery and loop clockwise; upstairs, stand well back to read monumental prints. Check what's on and pre-book if a headline show is running; some exhibitions are free, others ticketed. Allow 60-90 minutes, longer if you linger in the shop or catch a talk.
