n A small building (or "
vault") for the
remains of the
dead, with walls, a roof, and (if it is to be used for more than one corpse) a door. It may be partly or wholly in the ground (except for its entrance) in a cemetery, or it may be inside a church proper or in its
crypt. Single tombs may be permanently sealed; those for families (or other groups) have doors for access whenever needed.
