Ossuary is usually a vault or building where human skeletal remains are stored, mostly if burial space is scarce. A body is first buried in a temporary grave, then after some years the skeletal remains are removed and placed in an ossuary. The greatly reduced space taken up by an ossuary means that it is possible to store the remains of many more people in a single tomb than if the original coffins were left as is. Our model presents small underground chapel build as ossuary to store thousands of human remains. It seems it is old and deserted by now since one of side chapels is destroyed by nearby tree roots protruding through stone walls. But there is a candle burning a top large macabre candelabra holder… Perhaps this place serves as site for some sinister rituals?
