killing center

Also called extermination camps and death camps, these sites were designed specifically for mass murder. In 1940, persons with disabilities were murdered by gas chamber in early killing centers established in Nazi Germany under the Aktion T4 “euthanasia” program. Between 1941 and 1943, Nazis established six centers designed for killing Jews in Nazi-occupied Poland: Chelmno, Belzec, Sobibor, Treblinka, Majdanek, and Auschwitz-Birkenau.
