If you think you've seen all of Berlin, bear in mind that the city knows how to keep secrets... Under Berlin's pavements exists a world shrouded in darkness! Serving as bomb shelters during the Second World War, these underground caverns were later used during the Cold War as fallout shelters. Open to the public since 1987, the galleries and bunkers bear witness to this part of Germany's history in their own way. Traditionally less popular than the Brandenburg Gate and Checkpoint Charlie, the Berlin Underworlds Association is attracting increasingly more visitors. Don't wait for the last minute to arrive at the starting point of the tours! There is a choice of four itineraries: 'The Dark Worlds': a guided historical visit; 'From Flak Towers to Mounts of Debris': Enter a fascinating and devastated underground world; 'U-Bahn (the underground) and Bunkers in the Cold War': A political history of Berlin from an unusual perspective; and 'The Charm of Pneumatic Tube Transport': Berlin's smallest underground. Your entrance ticket entitles you one guided visit in either German, English or French depending on the tour schedule.
