The Memorial Cube is an innovative columbarium that can accommodate 4,000 spherical urns on an area of 25 m2. The exterior of the Memorial Cube can be freely determined. Solar panels make cabling unnecessary. The urns to be personalized are equipped with an RFID chip that is software linked to a deceased person. Using the Memorial App, relatives can place the urn in the Memorial Cube and, if necessary, remove it themselves. Life stories with photos, film and music are visible of all the deceased in the Memorial Cube. The Memorial Cube is available in various sizes and can also be installed underground. The Memorial Cube is particularly suitable for cemeteries and crematoria with limited space for graves, the many vacant churches and the loyal fans of the professional football clubs.
