Sobibor extermination camp
Lager III was the extermination area. It was kept separate from the rest of the camp, set back in a clearing in the forest and surrounded by its own thatched fence. Prisoners from Lager I were not allowed near Lager III, and were killed if the Nazis suspected that they had seen inside. Because few people who saw Lager III survived, there is little eyewitness testimony about this part of the camp. Historians know little about Lager III, except that it contained gas chambers, mass graves, and special separate housing for the Sonderkommando prisoners who worked there.
