It is incomplete, its lower portion broken away, but what remains is quietly arresting: a triple-line cross, incised or pock-marked into the stone, with triangular terminals from which broad ribbons of interlace spread outward. The slab measures roughly 78 centimetres tall and 45 centimetres wide, and it spent an unknown length of time buried or lost before a local parishioner found it in the adjacent Kilbixy graveyard. It now sits indoors, rescued from the ground but separated from whatever context it originally occupied.

The site of Kilbixy, whose older name Ceall Bhigsighe translates roughly as the church of Bigsech, was founded by St Bigseach, a figure associated with St Brigid of Kildare. That connection places the site within a network of early Irish monasticism linked to one of the country's most significant early Christian communities. The cross-slab itself is thought to date from the tenth or eleventh century, a date arrived at by comparing its design with similar stones bearing inscriptions. The style is described as an expansional cross, meaning the arms widen toward the terminals rather than remaining uniform in width, and the ribbon interlace framing those terminals is characteristic of a particular phase of early medieval Irish stonework. A cross-slab of this kind would have served a commemorative or devotional function, possibly marking a grave or acting as a focus for prayer within the monastic enclosure.
