Jasenovac Memorial Site is in the immediate vicinity of the former Jasenovac concentration camp, Camp III (Brickworks). In the Memorial Site the original sites of buildings and execution sites within the camp itself are marked by earth mounds and hollows. The path to the Flower Memorial is paved with railway sleepers. They denote symbolically part of the preserved railway track used to transport prisoners to the camp.
Along with the memorial area, Jasenovac Memorial Site is responsible for the original, preserved camp building known as The Tower, the Stara Gradiška Camp cemetery, the Roma cemetery in Uštica and the mass graves in Krapje, Mlaka and Jablanac.
The activities of Jasenovac Memorial Site have developed in different directions and include compiling, researching, scientifically processing, preserving and exhibiting the museum buildings and documents on how the Jasenovac Ustasha camp system operated; an educational programme; organising exhibitions and publications; ongoing co-operation with surviving prisoners and organising commemorative events in honour of the Jasenovac victims.
