Sachsenhausen concentration camp (officially called Konzentrationslager Sachsenhausen, or KZ Sachsenhausen) was a Nazi concentration camp that existed from 1936 to 1945. It was located near Oranienburg, just north of Berlin. Please note, that even though it was located in Oranienburg, it is different from Oranienburg concentration camp. Between 1936 and 1945, over 200.000 people were detained at KZ Sachsenhausen. Medical experiments were carried out in KZ Sachsenhausen to test the effectiveness of drugs. People from Sachsenhausen were also forced to help produce goods used for war (such as weapons, or ammunition).
