A recumbent slab, just under two metres in length and slightly wider at one end than the other, it carries an inscribed cross on its upper face. That asymmetry, 44 centimetres across at the western end and 60 centimetres at the eastern, is a small but telling detail, a reminder that these stones were shaped by hand for specific purposes, not cut to any standard formula.

The slab sits within the area known as Sevenchurches, the cluster of ecclesiastical remains at Glendalough whose popular name reflects the number of religious structures once gathered here. Recumbent cross-slabs of this kind are among the earliest forms of Christian grave marker found in Ireland, typically dating to the early medieval period, when a simple incised cross cut into a flat stone served to consecrate the ground beneath or to mark a person of some standing within a monastic community. This particular example was recorded lying approximately one metre east of the north-east corner of the structure known as the Priest's House, a small Romanesque building whose name is a later folk attribution rather than a documented historical function. The proximity of the slab to that building places it within one of the most densely layered corners of the entire site.
