Not far from Berlin, in the middle of Brandenburg, you can find Wünsdorf – a town formerly known as “the forbidden town”. The town used to be an important military base that was used during World War I and II by the German army, and later during the Cold War, the Sovjet Army used the complex. It’s purpose varied over time, and it saw many historic figures walk down its halls. For example, Claus Schenk Graf von Stauffenberg, who tried to assassinate Hitler was stationed there.
After World War II, the Soviets started to transform the military base into a whole military town with up to 70.000 soldiers living there
