The area known as Sevenchurches sits within the western valley at Glendalough, a monastic site associated with St Kevin that grew into one of the most significant ecclesiastical complexes in early medieval Ireland. This particular stone is not one of the site's celebrated high crosses. It is a plain Latin cross, cut in slight relief into the surface of the slab, on a face the stone itself has been slowly reworking: weathered into vertical ridges that run across the carving like lines of shallow grain.

Patrick Healy, writing in an unpublished OPW report from 1972, recorded its dimensions precisely: 0.98 metres high, 0.36 metres wide, and 0.08 metres thick. The material, mica-schist, is a metamorphic rock common to the Wicklow uplands, and its tendency to cleave and ridge under weathering explains the unusual texture Healy noted. In 1972, the slab was housed inside St Kevin's Church, one of the cluster of medieval structures that give the Sevenchurches area its name. At some point after that it was moved, and by 2005 it had been placed in the stone store at the Visitor Centre, presumably for protection from further exposure.

The slab is now held in storage rather than on open display, which means a visitor to Glendalough may not encounter it at all without specifically asking. Cross-slabs of this type, flat stones incised or carved in low relief with a simple cross, were produced at Irish monastic sites from the early medieval period onwards and served as grave markers or devotional objects. Most lack inscription or ornament, and their plainness is part of what makes them archaeologically interesting: they represent the more modest, everyday material culture of a monastic community, alongside the grander stonework that tends to draw attention.
