This Nazi-era bunker shelters one of Berlin's finest private contemporary art collections. Advertising guru Christian Boros acquired the behemoth in 2003 and converted it into a shining beacon of art. Book online (weeks, if not months, ahead) to join a guided tour (also in English) of works by such hot shots as Wolfgang Tilmanns, Olafur Eliasson and Ai Weiwei, and to pick up fascinating nuggets about the building's past incarnations as a tropical-fruit warehouse and techno and fetish club.
