The piece measures 0.56 metres by 0.33 metres and is only 0.06 metres thick, so it is not a large object, more the size of a substantial book than a monument. What survives of the carving shows the lower portion of a cross with T-shaped terminals, meaning the arms of the cross end in a horizontal bar rather than tapering to a point, set upon a base and enclosed within a rectangular border formed by two parallel lines running close together to create what is known as a ribbon border. Cross-slabs of this type are early medieval in character, typically associated with Irish monastic sites where they marked graves or served as devotional objects, and the combination of the T-shaped terminals and the simple incised border places this fragment within a recognisable tradition of insular stone carving.

The slab did not begin its recorded life in County Dublin. It was recovered during the 1980s from the graveyard of Gallen Priory in County Offaly, a site with early medieval ecclesiastical origins. How it came to be in Dublin after its recovery from Offaly is not detailed in the available record, compiled by Paul Walsh and uploaded in November 2011, but the transfer itself is part of a broader pattern in which architectural and sculptural fragments from rural or ruined sites end up in collections or institutions elsewhere, sometimes for safekeeping and sometimes through less careful routes. The Gallen Priory graveyard is separately catalogued, and this fragment is cross-referenced to that parent entry.

The present location is recorded as Newtown in the barony of Nethercross, County Dublin, though visitors hoping to see the piece should verify its accessibility before travelling, since fragments of this kind are often held in private custody, local authority storage, or ecclesiastical collections rather than on open display. The object is small enough to be easily overlooked even when accessible, so knowing in advance exactly what to look for, the surviving lower section of the cross composition and the double-line border, helps to make sense of what is otherwise a modest piece of stone. Its interest lies not in scale but in what it preserves of a carving tradition and in the slightly puzzling journey it has made from an Offaly graveyard to a Dublin townland.
