Sammlung Boros

A Reichsbahn bunker on Friedrichstraße houses this private collection of contemporary art, assembled by Karen and Christian Boros. Sculpture, photography and painting by international artists are spread over five floors, which architect Jens Casper turned into interlinked rooms. Some are classic white cubes, others still show traces of the bunker's years as a prison, storage depot and techno club. Each exhibition includes site-specific works, and visits are by guided tour only, booked in advance.
