At roughly 24 centimetres by 28 centimetres, and only 8 centimetres thick, it is easily overlooked, yet the carving is precise and deliberate: a ringed cross in low relief, with rounded hollows cut into each angle, and on the reverse, a plainer cross with the same hollowed angles. A small round boss, just 4 centimetres across and a centimetre high, projects from the top. These are early medieval stoneworking conventions, the kind of careful ornament associated with the monastic tradition in Ireland, compressed here into an object you could carry under one arm.

The slab belongs to the site known as St. Berrihert's Kyle, an ecclesiastical enclosure in the Ardane area of County Tipperary. A kyle, in this context, refers to a small sacred enclosure or cell associated with an early saint, and St. Berrihert is a figure connected with early Christian activity in the Glen of Aherlow region. The cross-slab sits in the western sector of an oval stone enclosure that was constructed by the Office of Public Works in 1946, built to gather and protect a number of early carved slabs that had survived on the site. The enclosure is stepped internally, a deliberate design to display the collection. Scholar Ó hÉailidhe, writing in 1967, catalogued this particular piece as slab 5A/5B, noting both faces in detail, and it is his description that remains the primary account of the carving.
