World Wide Rave in Villingen-Schwenningen, Baden-Württemberg, Germany
The photo was taken by Sandy Jeschke in Villingen (Villingen-Schwenningen), which is a small town in Baden-Württemberg, a federal state at the South-West end of Germany. Many people know this part of Germany as the Black Forest area. The background is the "Riettor" which is a part of the mostly still existing city wall, the oldest city tower, built in 13th century.
