Holocaust survivors who managed to reach Łódź planted their tree: oaks, maples, lindens, birches, hornbeams, beeches, pines, spruces and larches. The trees were numbered and entered into the register, and the survivors received certificates with the name and number of the tree. Along the avenue of Arnold Mostowicz there are plaques with the surnames and number of the survivor's tree. In total, 450 trees were planted throughout the park on an area of one and a half hectares. The target area of the park is 8.5 hectares, in this area there is a water reservoir on the Łódka River. Alleys and squares with gravel-clay surface and granite cubes were also created.
