If the wall of Berlin could talk, it would probably tell us more interesting stories than we could imagine and it would share with us some forgotten secrets of this incredible city. And probably, one chapter of its book would be about Devil’s mountain or, as the Germans call it, Teufelsberg.

What now is just an abandoned place marked by graffiti and inhabited by squatters, after the Second World War used to be one of the largest listening stations built by NSA (National Security Agency), to survey the radio emissions emanating from eastern Germany, the GDR, and part of Poland. The base has been closed for years and now Teufelsberg is just an attraction for photographers, film makers or common people coming to enjoy its special acoustic.

In here, on the top of the 115m tower, the sound is more than a sound. Every whisper is a small revolution. Your tiny voice is ten times stronger in the ball built upstairs and a clap of hands sounds like a clash of the titans. The wind brings its own contribution and makes the tower seem to be inhabited by monsters.

“We don’t want just a piece of cake, we want the whole bakery” states a graffiti line written on the wall. If this line would apply for sounds, here it’s totally true.

But it’s not only the sounds that make this place special. It is the entire appearance, its entire underground atmosphere. Plus, the beautiful view from above.

You could stay an entire day and not get bored, while the forest and the lakes you see from up there combined with the strange sounds, make Teufelsberg look like taken out of a happy-end ghost story.

I really recommend you go see this place. It’s quite far, but not really in the Land of Far Far Away. You just need to take the S-Bahn (and a camera:)) until Heerstrasse, and then walk for another 20 minutes near the forest. With a bike, it’s even easier. So… no excuses allowed!:)
