What do you call an above-ground structure that contains crypts for the entombment of caskets?

The term for an above-ground structure that contains crypts for the entombment of caskets is a mausoleum. Mausoleums provide a dedicated space for the burial of multiple individuals, often within compartments known as crypts or niches. This structure is typically more elaborate than standard burial methods and allows families to entomb their loved ones in a dignified, permanent setting. Mausoleums can be architecturally significant, serving both as a memorial and as a place for family visitation.

In contrast, a tombstone is a marker placed over a grave, a grave itself refers to an excavation in the ground where a body is buried, and a columbarium is specifically designed for the storage of cremated remains in urns. Each of these alternatives serves distinct purposes in cemetery operations but does not encompass the same characteristics as a mausoleum.
