There are several memorization options for cremation, including scattering cremated remains or keeping them in an urn. Scattering can occur in a cemetery scattering garden, or at sea. An urn can also be placed in a spot with special meaning, such as over a mantle in a home, or in an urn garden, community mausoleum niche, urn mausoleum (called a columbarium), or even buried in a gravesite space. Compared to other burial options, cremation service costs tend to be less expensive, particularly when planning and pre-paying a cremation. Viewings and full funeral services can also be held.
