A cover closes the open top, and one or more vault fasteners are provided so the container can be attached to a second container. The vault is configured to hold a plurality of urns side-by-side, and end-to-end. The urns are stored along each of a plurality of sidewalls, or along the periphery, or within the vault. The vault cover is attached with a keyed fastener. The key is used to remove the fastener and to lift the cover from the vault. At least one urn spacer is inside the chamber(s) spaces and locates the urns. The urn spacer may be stamped, and the stamped portion used for a memorial plaque. The container is cylindrical or polygonal (three, four, five, six and eight sidewalls). The vault is cast, molded, and/or in one piece. A memorial plaque impression may be cast on the vault.
