Abstract: A columbarium system for the storage of human remains that includes a plurality of similarly configured storage containers is disclosed. The storage container has walls that define an enclosure having an opening at one end with a mounting plate attached thereto. The mounting plate has a pair of tabs that are arranged on opposite sides of the mounting plate and one pair of receiving grooves arranged at opposite sides of the mounting plate. The receiving grooves are dimensioned for receiving a tab from another container so that an arrangement of containers can be formed by the interlocking engagement of the tabs and grooves in adjacently arranged containers. The storage containers are self-framing in that additional framing members are not required for the erection of the columbarium system.
