What is the designated space in a columbarium for the permanent placement of cremated remains called?

The designated space in a columbarium for the permanent placement of cremated remains is referred to as a niche. This term is specifically used within the context of cremation and memorialization, denoting a small compartment or recess designed to hold urns containing cremated remains. Niches are usually arranged in a wall structure, allowing multiple remains to be stored in a respectful and organized manner.

Each niche is typically marked and can be personalized with various memorialization options, such as plaques or inscriptions, to honor the individual whose remains are housed there. This form of memorialization allows for the safe and dignified preservation of cremated remains in a public or private setting.

In contrast, the other terms mentioned have different meanings within crematory and cemetery operations. For instance, a vault generally refers to an outer container used to encase a casket or urn, enhancing protection and permanence. A chamber usually indicates an enclosed space used for certain processes related to cremation, while a plot is commonly understood as a designated piece of land in a cemetery where a burial can take place. Understanding these distinctions further clarifies why 'niche' is the appropriate term in this context.
