Also known as "Boros Bunker" in English, this is one of my top 5 spots in Berlin you can't miss! Like the Reichstag, go online and book a tour (only way to access it) in advance otherwise it'll sell out. World class art collection - with Ai Wei Wei - in an old Nazi bunker that sheltered thousands of Germans during the war. You can actually see bullet holes on the outside of the building and spots where the toilets used to be inside the building. The family that now owns the building and art collection live in the penthouse apartment here. Really, really cool!!' Cost is 12 Euros, I believe. #nazi #germany #berlin #art #gallery #history #war
