07/20/2025 The castle was closed to visitors because it is being renovated. In front of the castle there is a memorial plaque that mentions that this castle was a concentration camp during the time of the Independent State of Croatia (NDH). Prisoners were segregated based on ethnicity, with the camp split into "Serbian-Yugoslav", "Jewish" and "Communist" sections.
On July 9, 1941, the first group, including Božidar Adžija, Otokar Keršovani and Ognjen Prica, was executed. The Communist Party reacted by organizing an impromptu prison break. On July 13, the guards were overpowered and all the remaining prisoners managed to escape. But the attempt soon turned out to be poorly organized and uncoordinated. Very quickly, most of the prisoners, including August Cesarec, were recaptured and shot in Maksimir and Dotrščina woods.
