English: Checkpoint Charlie "Checkpoint C" was the name given by the Western Allies to a crossing point between East Berlin and West Berlin during the Cold War, located at the junction of Friedrichstraße with Zimmerstraße and Mauerstraße, (which for older historical reasons coincidentally means 'Wall Street'). It is in the Friedrichstadt neighborhood, which was divided by the Berlin Wall. Many other sector crossing points existed in Berlin. Some of these were designated for residents of West Berlin and West German citizens. Checkpoint Charlie was designated as the single crossing point (by foot or by car) for foreigners and members of the Allied forces. (Members of the Allied forces were not allowed to use the other sector crossing point designated for use by foreigners, the Friedrichstraße railway station). The name Charlie came for the letter C in the NATO phonetic alphabet; similarly for other Allied checkpoints on the Autobahn from the West: Checkpoint Alpha at Helmstedt and its counterpart Checkpoint Bravo at Dreilinden, Wannsee in the south-west corner of Berlin. The Soviets simply called it the Friedrichstraße Crossing Point (КПП Фридрихштрассе) .

During its 28-year active life, the infrastructure on the Eastern side was expanded to include not only the wall, watchtower and zig-zag barriers, but a multi-lane shed where cars and their occupants were checked. However the Allied authority never erected any permanent buildings, and made do with the iconic wooden shed, which was replaced in the 1980s by a larger metal structure now on display at the Allied Museum in western Berlin. Their reason was that they did not consider the inner Berlin sector boundary an international border and did not treat it as such. In the years after reunification, a reproduction of the 1960s-era wooden shed was placed at the site of the original [Wikipedia.org]
