Crypt

A crypt (from Greek κρύπτη (kryptē) crypta "vault") is a stone chamber beneath the floor of a church or other building.

Originally, crypts were typically found below the main apse of a church, such as at the Abbey of Saint-Germain en Auxerre, but were later located beneath chancel, naves and transepts as well.

The earliest known origin of both is in the Ancient Greek κρύπτω, the first person singular indicative of the verb "to conceal, to hide".

In some localities, an above ground crypt is more commonly called a mausoleum, which also refers to any elaborate building intended as a burial place, for any number of people.

There was a trend in the 19th century of building crypts on medium to large size family estates, usually subtly placed on the edge of the grounds or more commonly incorporated into the cellar.
