What is another term for a "bone-pit"?

A bone-pit is often referred to as an ossuary. An ossuary is a storage place for human skeletal remains, typically used when individuals were buried in mass graves or when remains were exhumed and placed in a central location for various reasons, such as space management in cemeteries. Ossuaries can be found in both historical and contemporary settings, serving as a solution for the respectful re-interment of remains.

The other terms do not carry the same meaning. A grave box generally refers to a container used to hold the casket or burial materials at a grave site, while a cremation site indicates a location specifically intended for the process of cremating remains. A pit grave denotes a burial space but does not specifically imply the storage or collection of bones. Thus, ossuary accurately captures the essence of a bone-pit, emphasizing its function as a communal resting place for skeletal remains.
