The area which is now the Teufelsberg, used to be a landfill for 12 million cubic metres of WW II debris. Later on the US secret service built the world's most important listening post on the site.

For safety reasons this abandoned place may not be explored on your own. A security service guards the object and if you get caught on your own there, you will be reported to the police. There are guided tours however and the revenue created from them pays for the security expenses. Tour dates are published on the Teufelsberg website.

The former listening post is also popular as location for photo shootings or as movie set. For example the exciting closing scene of the modern Berlin vampire movie "Wir sind die Nacht" (among others with Karoline Herfurth and Nina Hoss) is filmed right here.

On top of that, familie use the Teufelsbergs for kiting and in winter as sledding hill. Other sports enthusiasts have conquered the site for paragliding, climbing or hiking.

Top10 Berlin tip: The view is not only spectacular in summer. Enjoy the fireworks of News Year's Eve here with loads of people marvelling at the sky over the city.
