Jasenovac concentration camp
The camp's size: Jasenovac was a complex of various camps, including Krapje and Brocice, Ciglana, Stara-Gradiska, Sisak, Djakovo, Jablanac, Mlaka, Draksenic, Gradina and Ustice, Dubica, Kosutarica, and Jasenovac's tannery. These camps and mass graveyards covered 120 square miles. In the list of names found in the Jasenovac memorial, only 4000 victims are from Stara-Gradiska, where inmates were killed with poison gas as early as 1942.  This suggests that the victim list may not be complete.
