Teufelsberg
Teufelsberg (“Devil’s Mountain”) is an artificial hill in the Grunewald forest in western Berlin, constructed between 1950 and 1972 from approximately 26 million cubic metres of rubble from the bombed city. On its summit, the United States National Security Agency operated a field station from the early 1960s until German reunification in 1990 that monitored Soviet and East German military and civilian communications across the Iron Curtain. The distinctive golf-ball-shaped radomes of the listening station remain standing as one of Berlin’s most recognisable Cold War landmarks, now a legal graffiti park and cultural venue open to visitors.

Overview
Teufelsberg offers a layered landscape where post-war urban history, Cold War surveillance, and contemporary street art converge. The hill itself is a monument to destruction and reconstruction: every cubic metre of rubble represents a fragment of pre-war Berlin buried beneath the new city. The NSA listening station above was one of the most strategically significant signals intelligence facilities in Western Europe during the Cold War, listening in on Warsaw Pact communications from its elevated position above the flat North German Plain. Today the site is a destination for history enthusiasts, street art lovers, and visitors seeking panoramic views over the city and surrounding Grunewald lakes.
History
After World War II, Allied authorities needed to dispose of enormous quantities of rubble from Berlin’s devastated buildings. Beginning in 1950, the rubble was systematically piled in the Grunewald on the foundations of an unfinished Nazi military-technical college (Wehrtechnische Fakultät) designed by Albert Speer, which was too solid to demolish. The mound was progressively raised through 1972. The US Army Corps of Engineers built the listening station on the summit in the early 1960s, its distinctive radomes housing radar dishes and antennae pointed east. The facility was abandoned after reunification and the land was sold for redevelopment, but financing repeatedly collapsed; the station fell into decay and became a magnet for urban explorers before being partially stabilised and opened as a guided tour and street art venue.
What you see
Three large white radome spheres crown the summit alongside rectangular concrete station buildings extensively covered in murals by Berlin and international street artists. The largest dome retains its acoustic properties and is used for music and art events. Inside the station, original infrastructure has been stripped but the bones of the surveillance facility remain visible: antenna mounts, cable ducts, and observation platforms. From the hilltop, on clear days, visitors can see across the Spree valley to the television tower at Alexanderplatz 15 km to the east, and over the Havel lakes to the south and west.
Cultural significance
Teufelsberg is one of the most tangible Cold War monuments in Berlin, a city already dense with such layers. Unlike the Berlin Wall — most of which was demolished — the listening station remains physically present and accessible, making it a rare first-person encounter with the infrastructure of the intelligence war. The hill itself is a literally built landscape, a city buried under a city, giving visitors an experience of urban archaeology unique in Europe.

Getting there
From central Berlin, take the S-Bahn to Heerstraße (S5) or Olympiastadion and walk approximately 30 minutes through the Grunewald, or cycle from Charlottenburg (approx. 6 km). Alternatively, take bus 218 toward the Grunewald. The site is not served directly by public transport; a forest walk is part of the experience. Parking is available near the Teufelssee lake at the forest edge.
