Stele or marker, usually stone, placed over a grave
A gravestone or tombstone is a marker, usually stone, that is placed over a grave. A marker set at the head of the grave may be called a headstone. An especially old or elaborate stone slab may be called a funeral stele, stela, or slab. The use of such markers is traditional for Chinese, Jewish, Christian, and Islamic burials, as well as other traditions. In East Asia, the tomb's spirit tablet is the focus for ancestral veneration and may be removable for greater protection between rituals. Ancient grave markers typically incorporated funerary art, especially details in stone relief.
