Checkpoint Charlie 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. The Soviet Union prompted the construction of the Berlin Wall in 1961 to stop Eastern Bloc emigration westward through the Soviet border system, preventing escape across the city sector border from East Berlin to 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.
Checkpoint Charlie has become one of Berlin's primary tourist attractions. An open-air exhibit was opened during the summer of 2006. Gallery walls along the Friedrichstraße and the Zimmerstraße inform on escape attempts, how the checkpoint was expanded, and its significance during the Cold War, in particular the confrontation of Soviet and American tanks in 1961.
