Dachau Concentration Camp was the first camp opened in Germany by the Nazi’s, in 1933.  I found visiting Dachau quite difficult and feel sickened thinking about how we as human beings treated each other ( I would say in the past, however, sadly some of this still goes on in parts of the world).   It’s an awful place and I felt quite depressed for a few days after visiting it.

Dachau served as a model for other concentration camps and a larger camp was later built in Auschwitz, which was in the German-occupied southern Poland.

It is located on the grounds of an abandoned munitions factory southeast of the medieval town of Dachau, about 16 km (10 mi) northwest of Munich in the state of Bavaria, in southern Germany.^[1] Opened in 1933 by Heinrich Himmler, its purpose was enlarged to include forced labor, and eventually, the imprisonment of Jews, ordinary German and Austrian criminals, and eventually foreign nationals from countries that Germany occupied or invaded. The Dachau camp system grew to include nearly 100 sub-camps, which were mostly work camps or “Arbeitskommandos,” and were located throughout southern Germany and Austria.^[2] The camps were liberated by U.S. forces on 29 April 1945.

Prisoners lived in constant fear of brutal treatment and terror detention including standing cells, floggings, the so-called tree or pole hanging, and standing at attention for extremely long periods.^[3] There were 32,000 documented deaths at the camp, and thousands that are undocumented. — Wikipedia
