Set into a recess in the outer wall of a small church on High Island, off the Connemara coast of County Galway, the stone served as a headstone for what is called a pseudo grave, a grave-shaped feature that may never have contained a burial at all. The slab was found still in position, its western face pressed against the stonework of the church wall, its decorated eastern face turned outward toward the graveyard. That concealed face was not simply blank, however, and what it carries makes the stone considerably more interesting than it might otherwise appear.

The slab is cruciform in shape with short side-arms, cut from garnet mica-schist, a locally available metamorphic rock with a faintly glittering surface. It measures 0.79 metres high, 0.28 metres wide, and just 0.03 metres thick. The visible eastern face bears a central roundel enclosing an equal-armed cross whose terminals are a mixture of straight and slightly forked ends, a detail that places it within a recognisable tradition of early Christian stone carving in the Irish west. A linked pair of bosses survives in the upper left quadrant, though the right quadrant has suffered damage. The hidden western face carries a simpler linear cross, also with forked terminals on the cross-head. The slab was probably reused, meaning it was not carved specifically for Grave 2 but brought from elsewhere and repurposed, a common enough practice on early monastic sites where good stone was scarce and older carvings were evidently not considered an obstacle. It is one of three decorated cross-slabs associated with this part of the graveyard, and the decoration on its eastern face closely resembles that found on a companion slab associated with Grave 1 nearby. The site as a whole was recorded by Fisher in 2014, drawing also on earlier work by White Marshall and Rourke published in 2000.
