With its weight of almost ten tons and a height of two and a half meters, the Schwarzacher mortar bell directly in front of the wildlife park is the largest bronze bell in southern Germany and the second largest bell in the history of the traditional Grassmayr bell foundry. Its imposing chime in E minor can be heard on Saturdays, Sundays and public holidays at 5 p.m. far beyond the borders of Schwarzach. Another eye-catcher in the sculpture park is the monumental stone mortar with a size of 2.05 meters and a weight of 6.9 t. Mortar bell, stone mortar and park are permanent loans or foundations from Dipl. Ing. h.c. Siegfried Genz.
