Checkpoint Charlie was a crossing point in the Berlin Wall 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. 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).
