Berlin in the cold war: on the top of an artificial hill called „Teufelsberg“ (devil‘s mountain) that was erected from the rubble of the final stages of the Second World War the NSA operated a huge field station essentially sitting in the heart of East Germany.

For a couple of years now the city of Berlin tried to get one or the other commercial project running but it all failed for either political reasons or mere incapability. Recently, the remaining security personal has been withdrawn and for a limited time it was possible to access the whole area.

The Chaos Computer Club undertook a couple of excursions to the field station and has put together a documentation with old maps, new photographs and explanations on how the facility was structured and operated: read NSA Field Station Teufelsberg Berlin – a late post mortem .

Enjoy!
