The Teufelsberg lies at the northern end of a large area of historic woodland, the Grunewald, bounded to the west by the River Havel and to its north by the gentle valley of the River Spree. The name of the Teufelsberg or Devil’s Mountain, created from unusable wartime rubble, might seem particularly appropriate, but was in fact derived from a small natural lake, the Teufelsee that lies to its south in the Grunewald. At the northern end of the Grunewald, and beneath what is the Teufelsberg, the architect Albert Speer planned to build a new university, including an army technical institute. In wartime Berlin, the Grunewald was a place of escape from an increasingly bomb-damaged city, but it also took on a more sinister function as its railway station became one of the main places of forced deportations to the east.
