Found embedded in the paved floor of an early medieval monastic cell on High Island off the Galway coast, this is not a monument displayed in situ or visible to passing visitors. It now sits in an Office of Public Works depot in Athenry, catalogued and stored, which is perhaps the quietest possible afterlife for an object with such a particular origin.

The slab was recovered from 'Cell A', a clochan, which is a dry-stone corbelled hut of the kind built by early Christian monks as individual living or sleeping quarters, situated to the north of the island's church. Two cross-slabs were found together from the same paved floor during recorded investigation of the site. This one measures 54 centimetres tall and 24 centimetres wide, cut from garnet mica-schist, a metamorphic rock whose flecked, glittering texture would have made it a striking choice even in the damp Atlantic light. The slab is cruciform in shape, meaning the stone itself was carved into the outline of a cross rather than simply having a cross incised upon it. One face carries a weathered linear Greek cross on the cross-head, the equal-armed form that appears widely in early Irish monastic carving. The stone is broken obliquely at the foot and damaged along the right side, marks of age and the rough conditions of the island itself. White Marshall and Rourke documented it in 2000, and Fisher examined it again in 2014, placing it within the broader material record of High Island's monastic community.
