Nazi Extermination Camps
The major extermination camps were in German-occupied Poland and included Auschwitz, Belzec, Chelmno, Majdanek, Sobibor, and Treblinka. At its peak, the Auschwitz complex, the most notorious of the sites, housed 100,000 persons at its death camp. This is a map where you can see the sites for where most of the atrocities were carried out towards innocent Jewish people.
