Bunker

The Bunker in Berlin-Mitte is a listed air-raid shelter.
Originally based on plans of the architect Karl Bonatz, it was constructed in 1943 by Nazi Germany to shelter up to 3,000 Reichsbahn train passengers. The square building has an area of 1,000 square metres and is 18 metres high; its walls are up to 3 metres thick. There are 120 rooms on five floors. In May 1945, the Red Army took the building and turned it into a prisoner-of-war camp. From 1949, it was used to store textiles and from 1957, as storage for dry and tropical fruit.

In the summer of 1992, it was turned into a hardcore techno club. Gabba, hard trance, house and breakbeat parties were held on four floors. However, after a raid in 1995 the events became more irregular. A further raid in 1996 placed severe building restrictions on the tenants, causing the club to close.
