Just over a half-hour from central Berlin, Sachsenhausen was one of Nazi Germany’s most infamous concentration camps. Intended primarily as a camp for political opponents of the Nazi regime, some 200,000 people were sent to Sachsenhausen and thousands died under the inhumane working conditions. Sadly the camp’s dark history continued even after the fall of the Nazis when it was also used by the KGB as a prison for opponents of the communist regime in East Germany. Today visitors can tour the site and a museum covering the camp’s history. Given the subject matter, some material covered at the site may be inappropriate for young children.
