Teufelsberg is an artificial hill in Berlin, Germany, in the Grunewald locality of former West Berlin. It rises about 80 meters above the Teltow Plateau and 120.1 meters above sea level in the north of Berlin's Grunewald forest. It takes its name from the Teufelssee (i.e. the devil's lake) in its southern vicinity.
The hill is made of rubble and covers a Nazi military-technical college, built during the Cold War. Famous place for street art enthusiasts, here you can photograph wonderful works that various street artists have imprinted on the walls of abandoned buildings.
