The Anhalter Bahnhof is a former railway terminus in Berlin, Germany, approximately 600 m (2,000 ft) southeast of Potsdamer Platz. Once one of Berlin's most important railway stations, it was severely damaged in World War II, and finally closed for traffic in 1952, when the GDR-owned Deutsche Reichsbahn rerouted all railway traffic between Berlin and places in the GDR avoiding the West Berlin area. The station's name lives on in the Berlin S-Bahn station of the same name, opened in October 1939 as part of the North-South S-Bahn link.

The Berlin Customs Wall was a ring wall around the historic city of Berlin, between 1737 and 1860; the wall itself had no defence function but was used to facilitate the levying of taxes on the import and export of goods (tariffs) which was the primary income of many cities at the time.
