Tresor (German for safe or vault) is an underground techno nightclub and record label. The club was founded in March 1991 in one of the vaults in the old Wertheim department store in Mitte, the central part of the former East Berlin, next to the famous Potsdamer Platz, however the history of the club goes back to 1988 when the electronic music label Interfisch opened the UFO Club in Berlin. UFO was the original centre of Berlin house and techno, but due to financial problems that club closed in 1990.
After UFO closed, Interfisch's head, Dimitri Hegemann and some investors in the club found the new space in East Berlin. This was advantageous timing, as it was only a few months before Germany unified. The vaults under the Wertheim department store proved to be the perfect location for a club, and Tresor quickly became the place to be in Berlin. Tresor continued to be a popular club to this day, having expanded several times to include an outdoor music garden, and a second club on the top floor of the Tresor building.
Tresor closed on the 16th April 2005, as the landlord plans to build offices on the Leipziger Straße location. It was open for each night of April, with the final event starting the Saturday night with queues stretching all the way down the road, and still going Monday morning. A new location is currently being sought for the seminal nightclub.
