A wooden or stone copy of an actual dwelling, buried under a barrow or kurgan, and used as a tomb for the dead. There is sometimes an overlap between the definitions of mortuary house and mortuary enclosure, but very different ritual ideas may be involved. A mortuary house often contains only a single corpse, and serves primarily as a sepulcher rather than as a charnel house in which bodies were accumulated. Grave goods might be included and, in some instances, an earthen mound (barrow) was raised over the mortuary structure.
