Checkpoint Charlie was a crossing point between East and West Berlin during the Cold War. Others on the Autobahn to the West were Checkpoint Alpha at Helmstedt and Checkpoint Bravo at Dreilinden, southeast of Wannsee, named from the NATO phonetic alphabet. Many other checkpoints existed, some for German citizens, others for foreigners and members of Allied forces. Checkpoint Charlie is at the junction of Friedrichstraße with Zimmerstraße and Mauerstraße (which coincidentally means 'Wall Street') in the Friedrichstadt neighborhood, in the heart of Berlin, which was divided by the Berlin Wall. The Soviets simply called it the Friedrichstraße Crossing Point.
