In total , about 95,000 Jews were deported to the Lublin Reservation . The main camp of the entire complex was set up in Bełżec initially ( before the construction of death camp ) 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 . Though the Burggraben camps were temporarily closed in late 1940 , many of them were reactivated in 1941 . Two other extermination camps , Sobibor and Majdanek , were later set up in the Lublin district also . The Lipowa camp became a subcamp of the latter in 1943 . The Nisko Plan was abandoned for pragmatic reasons ; nevertheless , the '' Zwangsarbeitslagers '' ( German for " forced labor camps " ) already established for DAW became the industrial base of other SS projects such as Ostindustrie . A number of them functioned until '' Aktion Erntefest '' , others beyond the massacres
