The five-sided Verkehrsturm or traffic tower in the photo contained  the first traffic lights in Germany, is in place , only installed in December 1924 with traffic lights, but removed less than 13 years later in 1937 when, due to construction of the Potsdamer Platz underground S-Bahn station, a five-aspect suspended traffic light was installed above the street. In 1997 a reconstruction in exact detail was placed in Potsdamer Platz, currently at the south entrance of the regional station, with changing lights but not directing traffic.
