Many families, who choose cremation, wish to have all or a portion of the ashes placed in permanent memorials. This allows friends and family to have a place to return for memorialization. Many find it an important part of the grieving and healing process. Many wonderful options exist today.
Family Plot
If a family has an existing plot at a cemetery and wishes to bury cremated remains, the urn can be interred there. It is up to the individual cemetery if they allow multiple internments into a single space. If you want to be in the same cemetery as your family but do not wish to be buried, many cemeteries have mausoleums to accommodate cremated remains.
Urn Gardens & Scattering Gardens
Portions of some cemeteries / memorial parks are designated for cremated remains. Check with the cemetery in which you are interested to find out what special accommodations they make for cremated remains. Some of the modern cemeteries have dedicated special areas for cremated remains that include special scattering gardens, areas for permanently holding remains and even small chapels nearby for gatherings.
Columbarium Niche
A columbarium wall contains recessed spaces specifically designed for urns. They come in a variety of styles and sizes. Some columbariums allow room for personal items to be added along with the urn or have enough space for multiple urns.
