Permanent niches for the entombment of cremated remains are available in Columbariums at the Cemetery. The columbariums are made of solid granite. Each niche can accommodate two urns of appropriate size. The front panel is engraved with pertinent information. Columbaria are a building type dating back to the Etruscans, where urns holding cremated remains were placed behind memorial plaques.

The Columbaria units have numerous Niches available on both sides. They are located throughout the Cemetery grounds.
