Abstract: A modular memorial marker for marking a gravesite. The marker is created from a top shell having a top and a plurality of sides and a bottom shell which create a cavity into which a filler material is inserted to provide support for the top surface. Selected external elements, such as nameplates and decorative elements, are secured to the top surface of the marker. Selected internal elements, such as storage compartments and bolt receiving slugs, are provided under the top surface in the filler material or metal frame. The marker may be mounted on a slab and the entire unit is installed at the gravesite.
