What makes it quietly remarkable is that it carries carved decoration on both faces: the lower part of a Latin cross in low relief on one side, with double-rounded hollows cut into the angles where the arms meet the shaft, and a closely related cross design on the reverse. Two sides of the same modest stone, each bearing a version of the same ancient motif.

St. Berrihert's Kyle is an early ecclesiastical enclosure, the word "kyle" deriving from the Irish for a narrow wood or secluded place, and the site preserves a collection of early medieval carved slabs associated with local early Christian practice. The particular wall on which this slab now rests is part of an oval stone enclosure, stepped internally, that was constructed by the Office of Public Works in 1946 to gather and protect the various loose stones and slabs found at the site. The slab itself, catalogued as 20A/20B by the scholar Ó hÉailidhe in 1967, measures roughly 23 centimetres by 18 centimetres, with a thickness of just over 6 centimetres; a fragment, in other words, rather than a complete monument. Whether it was always this size or whether it represents the surviving lower portion of a larger cross-slab is suggested by its own description, which notes only the lower part of the cross on the principal face.
