Teufelsberg Radar Site, Berlin

The Teufelsberg radar site, nestled atop a man-made hill in Berlin, was once a crucial Cold War listening station operated by the United States. Built atop the rubble of World War II, its domes housed radar equipment used to intercept Soviet communications. Abandoned after the Cold War, the site now stands as a haunting relic, attracting urban explorers and artists drawn to its eerie atmosphere and graffiti-covered surfaces.
