In total, about 95,000 Jews were deported to the Lublin Reservation.[6] The main camp of the entire complex was set up in Bełżec initially (before the construction of death camps) for the Jewish forced labor. In March 1942 it became the first Nazi extermination camp of Operation Reinhard, with permanent gas chambers arranged by Christian Wirth in fake shower rooms.[7] Though the Burggraben camps were temporarily closed in late 1940, many of them were reactivated in 1941.
