In the organizer's words:

We will explore the site of the former listening station by the light of our flashlights. Our extraordinary discovery tour will take us through abandoned corridors and stairwells, former offices and rooms that are otherwise not open to the public. We follow the traces of history from espionage, secret services and the Cold War to its current use as a place for art, culture and remembrance. The excitement is followed by relaxation: after the tour, a cozy get-together in the open air with a drink awaits us. Please bring a strong flashlight, a large portion of curiosity and, of course, nerves of steel, as the site seems even more mysterious in the dark.
