Checkpoint Charlie (or "Checkpoint C") was the name given by the Western Allies to the best-known Berlin Wall crossing point between East Berlin and West Berlin during the Cold War (1947–1991).
Located on the corner of Friedrichstraße and Zimmerstraße, it is a reminder of the former border crossing, the Cold War and the partition of Berlin. The barrier and checkpoint booth, the flag and the sandbags are all based on the original site – and are a popular subject for photos. It’s no wonder that Checkpoint Charlie is one of the sights of Berlin that you really should see. East German leader Walter Ulbricht agitated and maneuvered to get the Soviet Union's permission to construct the Berlin Wall in 1961 to stop Eastern Bloc emigration and defection westward through the Soviet border system, preventing escape across the city sector border from communist East Berlin into West Berlin. Checkpoint Charlie became a symbol of the Cold War, representing the separation of East and West. Soviet and American tanks briefly faced each other at the location during the Berlin Crisis of 1961. After the dissolution of the Eastern Bloc and the reunification of Germany, the building at Checkpoint Charlie became a tourist attraction. It is now located in the Allied Museum in the Dahlem neighborhood of Berlin.
