1Landmark
Built in 1941 as one of Berlin's massive flak towers designed to defend the city and shelter civilians from Allied bombing raids, the Humboldthain tower proved too solid to fully demolish after the war, so Allied forces instead buried much of it under rubble, leaving fragments and observation platforms exposed above what is now a public park. Guided tours, which must be booked ahead, lead visitors into the surviving bunker interior to see the tower's original structure up close, an experience reviewers describe as genuinely gripping for anyone interested in the war's physical remnants.
Above ground, the rubble hills offer good views over the surrounding cityscape and have become popular with casual park visitors unaware of what lies beneath their feet. Budget around 90 minutes if you're taking the full underground tour.
