The Nuns of Dachau.
copyright, 2017.
Heinrich Himmler, as police president of Munich, officially described the camp as "the first concentration camp for political prisoners." It was located on the grounds of an abandoned munitions factory near the northeastern part of the town of Dachau, about 10 miles northwest of Munich in southern Germany. Many Catholic priests were arrested and placed into the camp, and to this day nuns pray for the priests that died in the barracks under the Nazi regime.
