What is columbarium?

By Karl-Gustav Kallasmaa

Published August 2025 · Updated February 2026

A columbarium is a structure or wall containing niches that hold urns of cremated remains. It is often located in a cemetery, mausoleum, or place of worship, and provides a permanent, visitable place for ashes.

Each compartment in a columbarium is called a niche, and a niche may hold one or more urns. Fronts are commonly granite, marble, glass, or bronze and can be engraved with names and dates. A columbarium may stand outdoors as a garden wall, occupy a room inside a mausoleum, or be built into a church, synagogue, or memorial garden.

As cremation has become the most common choice in the United States, columbaria have grown more widely available. A niche is a frequent choice for families who want cremation but still want a fixed, visitable place to gather and remember, rather than scattering the remains or keeping the urn at home.

Costs vary by cemetery and by the niche's size and position — eye-level and glass-front niches typically cost more than those near the floor or ceiling. The price you are quoted may or may not include the urn, the engraving, and the fee to open, place, and seal the niche, so ask for an itemized breakdown before buying.
