Белжец
The Bełżec extermination camp, set up near the railroad station of Bełżec in the Lublin District, began operating officially on March 17, 1942, with three temporary gas chambers later replaced with six made of brick and mortar, enabling the facility to handle over 1,000 victims at one time. At least 434,500 Jews were exterminated there. The lack of verified survivors however, makes this camp much less known. The bodies of the dead, buried in mass graves, swelled in the heat as a result of putrefaction making the earth split, which was resolved with the introduction of crematoria pits in October 1942.
