Chełmno extermination camp
Chełmno nad Nerem is a village in Poland, annexed to Nazi Germany in 1939 and renamed "Kulmhof" during German occupation. As the Nazis themselves exclusively referred to the camp as "Kulmhof", the name "Chełmno extermination camp" is not historically accurate, with its use perhaps deriving from the Main Commission for Investigation of German Crimes in Poland shortly after the war.
