The function of a vault is primarily to entomb various types of human remains, which includes caskets and other forms of interment. The vault is designed to protect the remains from the weight of the earth above and to provide a barrier against water and moisture, which can be detrimental to the integrity of the casket and its contents. This protective role is critical in ensuring the dignity of the deceased and maintaining the conditions of the burial site.

While a vault may have aesthetic features, its main purpose is not decorative. It is not intended to serve as a temporary holding area—this would be more closely associated with a morgue or holding facility prior to the final disposition. Additionally, it does not primarily serve as a housing unit for memorial artifacts, which are often displayed separately in a funeral home or memorial park. Thus, the focus on entombment and preservation underscores why this statement accurately captures the essential role of a vault in mortuary practices.
