The carving is on the wooded path between the upper and lower parking lots, near the columbarium.
The remains from the mass grave were placed in a columbarium built underground, beneath an artificial hill, and consecrated in 2004.
The columbarium was added to the nave in the 1950s, and the basement was remodeled at some point.
Numbers after some entries indicate niches in the columbarium, in other cases the ashes were scattered.
Remains have been found of ancient buildings, cisterns, grape presses and caves, one with a columbarium.
Columbarium niches have even been made a part of church buildings.
A columbarium was also incorporated into the design, with space for 1,400 niches.
The courtyard is a memorial garden and contains a columbarium with 36 niches for the interment of cremated remains.
