Nazistvakten Josef S, 100, ställs inför rätta i Tyskland

Sachsenhausen (German pronunciation: [zaksn̩ˈhaʊzn̩]) or Sachsenhausen-Oranienburg was a German Nazi concentration camp in Oranienburg, Germany, used from 1936 to the end of the Third Reich in May 1945. It mainly held political prisoners throughout World War II. Prominent prisoners included Joseph Stalin's oldest son Yakov Dzhugashvili, assassin Herschel Grynszpan, Paul Reynaud the penultimate Prime Minister of France, Francisco Largo Caballero Prime Minister of the Second Spanish Republic during the Spanish Civil War, the wife and children of the Crown Prince of Bavaria, Ukrainian nationalist leader Stepan Bandera, and several enemy soldiers and political dissidents. Sachsenhausen was a labor camp outfitted with several subcamps, a gas chamber, and a medical experimentation area. Prisoners were treated harshly, fed sparingly, and killed openly. After World War II, when Oranienburg was in the Soviet Occupation Zone, the structure was used by the NKVD as NKVD special camp Nr. 7. Today, Sachsenhausen is open to the public as a memorial.
