The Topography of Terror is an outdoor museum in Berlin, the capital of Germany. It is located in Niederkirchnerstrasse, formerly Prinz-Albrecht-Strasse, on the site of buildings which during the Nazi regime from 1933 to 1945 were the headquarters of the Gestapo and the SS, the principal instruments of repression during the Nazi era. The buildings that housed the Gestapo and SS headquarters were largely destroyed by Allied bombing during early 1945 and the ruins demolished after the war.
