Tresor

Housed in what was formerly the main central-heating power station for East Berlin, the colossal location is breathtaking, and since only a tiny portion of its 28,000sq m (300,000sq ft) is in use, there's plenty of room for future development in what is intended to be not just a club, but a huge centre of alternative art and culture. The basement floor is an experience you'll not forget; a black hole occasionally punctuated by flashing strobes with some of the loudest, hardest techno you are likely to hear.
