The cross, measuring roughly 40 centimetres long and 34 centimetres wide, was removed from Sceilg Mhichíl, the extraordinary early medieval monastery built on a rock pinnacle some 12 kilometres off the Kerry coast, and is now held at the Office of Public Works National Monuments Depot in Killarney.

On the island, the cross had stood on a leacht at the inner end of the entrance passage to the main terrace. A leacht is a low, flat-topped stone structure associated with early Irish monasticism, typically used for prayer or commemoration, often marking a significant threshold or devotional point within a monastic enclosure. Its position at the inner end of the entrance passage would have placed it at a meaningful transitional point, where monks passed from the approach route onto the main terrace of the settlement. The damage to its head and arms means much of whatever carved detail it once carried is now lost, though the slab itself survives intact enough to have been recorded and measured.
