Teufelsberg
"Devil's Mountain" is an artificial hill in the Grunewald forest, built almost entirely from the rubble of bombed Berlin after WWII — and it's hiding two histories stacked on top of each other. This is the Cold War's intelligence-gathering side, physically the most striking site on this list.
What's actually buried underneath it
Beneath the rubble lies an unfinished Nazi-era military-technical college, a building the Allies found too structurally reinforced to demolish easily after the war — so they buried it under an estimated 25 million cubic metres of wartime debris trucked in from across the city instead, creating Berlin's highest point at roughly 80 metres. The irony was not lost on anyone: a monument to destruction became the literal foundation for a Cold War listening post.
Field Station Berlin
From the 1950s, the US Army — later joined by British forces — built a signals-intelligence facility on top of the hill, using its elevation and clear line of sight deep into East German and Soviet territory to intercept radio and telecommunications traffic. It became one of the most important Western listening posts of the entire Cold War, its presence an open secret behind a heavily restricted perimeter. The station's distinctive white radome domes, which sheltered the antenna equipment, remain the site's most recognisable feature and are still standing today.
Decommissioned, painted, and open for tours
The radome towers
Several of the original geodesic radome structures are accessible on a guided tour, giving a genuine sense of scale that photographs from the ground don't convey.
Large-scale street art
Since decommissioning in the 1990s, the buildings have been extensively covered in murals and graffiti by artists from around the world, giving the site a second, very different visual identity layered over the original architecture.
The view
As Berlin's highest natural-plus-rubble point, the site offers a genuinely wide panoramic view over the surrounding Grunewald forest and the city skyline beyond.
Book ahead, budget the travel time
- Access is by paid guided or self-guided ticket only — walk-up entry without a ticket is not reliable, book in advance especially on weekends.
- It's genuinely out of the central-city cluster: budget real travel time via S-Bahn to Heerstraße plus a walk or shuttle up the hill, closer to 30–45 minutes each way from central Berlin.
- Footwear matters — the site is a mix of gravel paths, uneven ground, and stairs inside the towers.
- Because of the travel time, this pairs best as a dedicated half-day rather than squeezed between central sites.
Getting there
S-Bahn (S3, S7, or S9) to Heerstraße, then a signposted walk or seasonal shuttle up to the site entrance.
