Berlin Bunkers, Germany
Incredible secrets lie under the now peaceful city of Berlin. Once the epicenter of World War II, Berlin saw brutal war crimes and can’t forget the Nazi concentration camps.
The Berlin Bunkers were originally intended to shelter the citizens from the air raids during the war. A few of these bunkers also acted as defensive shelters during the nuclear Cold War conflict.
After that, the bunkers remained empty for the remainder of the twentieth century until 1997, when they were rediscovered. They’re an insight into the atrocities committed in World War II and, therefore, now serve as museums operated by Berliner Unterwelten eV.
