In general, crypts refer to the vault that is often located below a church or on the grounds of a memorial facility within a mausoleum to house a casket and the departed, while a mausoleum is a stately and serene building that may house one or more crypts.

The main difference between Mausoleum and Crypt is that the Mausoleum is a monument enclosing the interment space or burial chamber of a deceased person or people and Crypt is a stone chamber or vault beneath the floor of a burial vault.
