The abandoned Cold War field station at the top of Teufelsberg is not very discreet. Three huge bulbous globes crown the main building, where the NSA once intercepted East Berlin and Soviet communications. The middle one is perched atop a six story high tower rising above the trees of Grunewald. It looks, for lack of a more elegant way of putting it, like a giant dick and balls.

Teufelsberg means devil’s mountain. Not to be confused with Teufelswerk, which means the work of the devil. No, it’s a man-made mount alright. 12 million cubic meters of war rubble. That’s about 400.000 bombed houses. 3% of the more than 400 million cubic meters of rubble that dressed German cities not so long ago. Collected by Berlin’s Trümmerfrauen, and dumped here. Buried beneath that lie the remains of a Nazi military training academy. Designed by Hitler’s chief architect Albert Speer. Envisioned as part of the University City in the world capital Germania. Once destined to welcome the Reich’s blunted and brutalized Napola graduates. It takes no more than ten to fifteen minutes to ascend, usually. But we need twenty this time, because two days ago storm Xavier left an array of fallen trees in it’s wake that we have to clamber over on our way up.

The reward is the ever-changing street art on display in and on the ruins. And a spectacular view of the sunset, which we watch from the roof of the main building. And if you climb the highest tower - the penis - you can enter the globe at the tip through a trap door. Inside here the light is very dim. Even before the last of the sunrays slip away behind the horizon. The space is watched by two large, faceless, hooded figures spray painted on to the inner shell of the globe. But the best part is the echo. Everything you do in here echoes. Every step, every shuffle. Everything you say, even a whisper, swaddles itself around you in repitition. It’s exactly how you’d imagine someone loosing their mind.
