‘The Hill’ is the name Teufelsberg earned from American soldiers who worked there beginning in 1961, when the US National Security Agency built one of its largest listening stations on top of Teufelsberg. In 1963, construction of a more permanent facility on top of Teufelsberg began and continued monitoring the Soviet, East German and other Warsaw Pact nations military traffic. At the end of East Germany in 1990, the Field Station Berlin was decommissioned.
