Teufelsberg

Teufelsberg was an NSA listening post during the Cold War in Germany. US agents listened to radio transmissions from the GDR. The site has an interesting history. Under the 400,000 buildings worth of rubble that the tower sits on is a Nazi Military Technical College designed by Albert Speer.

The site is abandoned now, but is sometimes used by artists because of its acoustics (the main tower has a fully enclosed geodesic sphere), surfaces which are conducive to projection, and historical significance.
