Fodor's Expert Review Sammlung Boros
This private collection has become one of Berlin’s star attractions, thanks to its unusual location inside a hulking WWII bunker in Mitte. Contemporary art collector Christian Boros bought the bunker in 2003 to house his art, and built a glass penthouse on top to house his family. The best works are those created specifically for the space by well-known artists such as Ai Weiwei, Olafur Eliasson, and Tomás Saraceno. Since this is a private home, admission is only allowed on guided tours, which take place Thursday to Sunday and can booked online. The tours are popular, so book as early as you can (months in advance).
