A 30-year-old icon of Berlin's clubbing scene and a huge influence on the country's techno culture, Tresor was originally located in the vault of a department store in East Berlin. After some years of difficulty, it reopened in 2007 in a 236,000-square-foot abandoned power plant. The new digs carry on its techno revolution tradition: The derelict space of the factory, complete with a state-of-the-art sound system and red lighting, is an ultra-intense experience for even the most passionate clubber. It includes three interlinked floors play house and electronic music, while an almost-100-foot tunnel leads to the main dance floor.
