Sobibor extermination camp
Sobibor was an extermination camp, not a concentration camp. This meant the camp's only purpose was to murder Jews. The vast majority of prisoners were gassed within hours of arrival. People who were not killed immediately were forced to work in the camp. Few survived more than a few months. In total, some 170,000 to 250,000 people were murdered at Sobibor. Only three other camps (Belzec, Treblinka, and Auschwitz) killed more people than Sobibor.
