Chelmno

Chelmno was a Nazi concentration and extermination camp in Poland during World War II, operational from 1941 to 1943. It was responsible for the systematic murder of approximately 150,000 Jews, Roma, and others targeted by the Nazis. The camp used mobile gas vans to kill victims quickly and secretly, making it one of the earliest sites of mass extermination in the Holocaust. Chelmno’s operation exemplifies the industrialized, bureaucratic nature of Nazi genocide, and it remains a symbol of the atrocities committed during this dark period in history.
