5229'50"N 1314'26"E US National Security Agency (NSA) built one of its largest listening stations on top of the Teufelsberg, rumoured to be part of the global ECHELON intelligence gathering network. The hill was located in the former British sector of Berlin.
Mobile listening units would drive to different locales in West Berlin hoping to gain the best vantage point for listening to Soviet and East German military radio traffic. One such unit drove to the top of Teufelsberg and discovered a marked improvement in listening ability. This discovery eventually led to a large structure being builtl, which would be run by the NSA. At the request of US government, ski lifts were removed because they allegedly disturbed the signals.
The station continued to operate until the fall of East Germany and the Berlin Wall, but after that the station was closed and the equipment removed. The buildings and radar domes are to be demolished.
