Teufelsberg
The Teufelsberg (German for Devil's Mountain) is a hill in Berlin, Germany, in the Grunewald locality of former West Berlin. It rises about 80 metres (260ft) above the surrounding Teltow plateau and 120.1 m above the sea level, in the north of Berlin's Grunewald Forest. It was named after the Teufelssee (i.e. Devil's lake) in its southerly vicinity.
