Camp III (Brickworks) and the execution site in Donja Gradina were the largest in the Jasenovac Ustasha concentration camp system. Up to the beginning of 1942, when liquidations of prisoners began in Donja Gradina, most inmates were killed inside the camp or on the left bank of the River Sava.
A special detail of prisoner-gravediggers was ordered every day to bury the bodies in huge trenches dug close to the camp fence, in a place called Limani (at the southeast corner of the main camp), and inside the camp itself.
During the re-ordering of the memorial site in Camp III (Brickworks), the mass graves in the Limani camp cemetery were also re-ordered and marked. There are seven mass graves, with a total surface area of 1,175 m².
In 2002 a bronze plaque with an inscription bearing verses from a poem by Ivan Goran Kovačić, Jama (The Pit), was moved from the area in front of the Memorial Museum to Limani. It reads:
“THE FINAL LIGHT BEFORE THE FRIGHTFUL NIGHT
THE LIGHTNING SWOOPING OF THE POLISHED KNIFE,
THE CRY TO WHITE STILL IN MY BLINDED SLIGHT,
THE BLEACH-WHITE BODIES OF THE MURDERERS,
WHO STRIPPED THEIR TORSOS FOR THEIR SWEATY TASK -
WAS DAZZLING EVEN TO MY BLINDED MASK.”
