We are heading for Berlin’s second highest hill, the renowned Teufelsberg 'Devil’s Mountain' born of rubble from the Second World War. Since then the hill has been greened and used for all kinds of sports. In 1986, it even hosted World Cup parallel slalom races. The crest of the hill is dominated by the former US army listening station, used by the Allies during the Cold War to intercept East Bloc radio communications. Over the last years, the decaying futurist-looking station has attracted Berlin’s club scene and film shoots – and is presently home to interventions by international artists. On a site tour, you’ll still find many things recalling Berlin shortly before the Wall fell.
