Now kept at the National Monuments Depot in Killarney under the care of the Office of Public Works, this piece was originally found on Sceilg Mhichíl, the remote pyramidal rock rising from the Atlantic some twelve kilometres off the Kerry coast, where early Christian monks established one of the most austere monastic settlements in Ireland. The fragment measures just 0.24 metres long, 0.18 metres wide, and 0.05 metres thick; a rounded head survives, along with the upper portions of two short rounded arms, each retaining traces of a rounded angle at the junction. The lower parts of the arms and the shaft are entirely gone.

What remains is enough to identify it as a cross of a type associated with early medieval Irish monasticism, when stone crosses served as markers of sacred space, focal points for prayer, and signs of territorial or spiritual boundary. The rounded form of the head and arms is consistent with early cross-slab and free-standing cross traditions found across Irish monastic sites, though the precise date of this piece is not established. Its original location on Sceilg Mhichíl, a site occupied by monks from perhaps as early as the sixth or seventh century, places it within one of the most isolated and demanding of all Irish monastic communities. That such a fragment survived the crossing to the mainland and entered formal care speaks to the ongoing effort to account for everything the island once held.
