Sachsenhausen or Sachsenhausen-Oranienburg was a Nazi concentration camp in Oranienburg, Germany, used primarily for political prisoners from 1936 to the end of the Third Reich in May 1945. After World War II, when Oranienburg was in the Soviet Occupation Zone, the structure was used as an NKVD special camp until 1950. The camp ground with the remaining buildings is now open to the public as a museum.
