The Abandoned Cold War Listening Station via Neatorama
On a hill called Teufelsberg (Devil’s Mountain) near Berlin, an abandoned facility complete with “radar domes” stands. It was once used as a listening station for the US to intercept Soviet communications, and then abandoned when West and East Berlin were reunited. It was built over top the remains of a Nazi war college. Exploring this station is difficult, as it is deteriorating. One of the dangers is an open 10-story elevator shaft!
