It measures roughly half a metre tall and a quarter of a metre wide, and yet carved into its face, in low relief no deeper than thirteen millimetres, is a Latin cross with slightly rounded hollows cut into the angles where the arms meet the shaft. The care in those hollowed angles suggests a deliberate aesthetic choice by whoever shaped it, the background cut back a little deeper there to give the cross a subtle presence without any grandeur.

The enclosure that now houses the slab and its companions was constructed in 1946 by the Office of Public Works, built to a stepped oval plan to gather and protect the collection of early medieval carved stones associated with this site. The place itself, St. Berrihert's Kyle, is an ecclesiastical enclosure, a term referring to the bounded sacred precinct that typically surrounded an early Irish church or monastic cell. St. Berrihert is an obscure early Christian figure, and the Kyle, meaning a narrow wood or secluded place in this context, retains something of that atmosphere of deliberate withdrawal. The slab was catalogued as number 36 by the scholar Ó hÉailidhe in 1967, who noted that its reverse face remains hidden, presumably set against the ledge on which it rests, leaving whatever marks or plain stone lie on the back undescribed.
