Sachsenhausen (German pronunciation: [zaksn̩ˈhaʊzn̩]) is a district on the Havel River in the north of the town Oranienburg, 35 kilometres north of Berlin in Germany. As of December 2005[update] it had a population of 2,735. The district's name means 'Houses of the Saxons'.
The area became notorious for the nearby site of the Nazi concentration camp - also called Sachsenhausen - which operated from 1936 to 1945.
For five years after World War II the Soviets used the facility as Special Camp No. 7 (later Soviet Special Camp No. 1).
