Adjacent to the Chapel, the indoor Columbarium is designed specifically to house cremated remains. Niches of various sizes, some constructed to hold up to four urns, are enclosed by glass panels. Inscriptions are either located on name plates or etched directly onto the urns. Diamond-patterned windows flood the Columbarium with a soft glowing light, creating an atmosphere of serenity and beauty.

Maple Hill offers outdoor Columbarium niches as well. As with the indoor ones, these niches can hold up to four urns, with the inscription located on the front of the niche.

Urns for burial or the permanent storage of cremated remains are displayed at the office of the Crematory.
