Dachau

Dachau concentration camp (German: Konzentrationslager (KZ) Dachau), was the first of the Nazi concentration camps opened in Germany, located on the grounds of an abandoned munitions factory near the medieval town of Dachau, about 16 km (9.9 mi) northwest of Munich in the state of Bavaria, which is located in southern Germany. Opened 22 March 1933 (51 days after Hitler took power),[1] it was the first regular concentration camp established by the coalition government of the National Socialist Party (Nazi Party) and the German Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."

Dachau concentration camp in The War That Came Early
After the General’s Plot failed in removing Adolf Hitler, the survivors of the coup were sent to Dachau. Despite it's terrifying reputation many Germans still talked about it, and when ever it was brought up, it was enough to kill a conversation.
