A niche is a permanent, above-ground location in which to place an urn that contains cremation ashes. Niches are typically located in a cemetery, mausoleum, or chapel. It can stand on its own or in an arrangement of niches, called a columbarium.
A columbarium is a structure used to store and often display urns containing cremated remains. The structure is typically a wall, room, or building, usually made of brick or concrete. Niches and columbariums can be located indoors or outdoors.
