Teufelsberg Spy Station

Teufelsberg sits atop an artificial hill built from wartime rubble in the Grunewald forest west of Berlin, its ruined geodesic radomes and abandoned NSA listening towers rising above the treeline. The domes face open sky in most directions, so the site works from any angle, but afternoon side-light picks out the torn white fabric and rusted lattice of the radomes against the surrounding pine forest, while overcast days give flat, moody tones that suit the derelict, Cold War atmosphere better than harsh sun. Autumn and winter, when the surrounding trees are bare, open sightlines toward the towers from the approach path, while summer's full canopy screens the climb until the final approach. The site draws a steady stream of photographers and urban explorers on weekends, when guided tours run and access is easiest, but lone unguided entry is not permitted; a paid ticket for the guided or self-guided access covers entry to the towers and domes. There is no legal drone use without prior permission, since the site sits near flight paths and within Berlin city limits.
