What is a "columbarium"?
A columbarium is an above ground structure specifically used for the interment of ashes or cremated remains. There's many different types of columbariums. Depending on the kind of urn that you want to use, you should really check with the cemetery to make sure that they're going to allow you to use those types of urns. Some columbariums actually have glass fronts on them so you can put a decorative urn inside and see the actual urn itself that your loved one's been placed in. The fees associated with purchasing a columbarian will be the actual space itself, opening and closing, any sort of epitaph that you want to place on there, like a marker. You can also place flower vases on the outside of the niche space, which is what the space is called in the columbarium that your ashes go.
