The west wall has been swallowed into the ringfort's surrounding bank, and the remaining walls to the north, south, and east survive only as low earthen ridges, rising at most to about one and a half metres. There are no visible window or door openings. What does remain with some clarity is a drystone altar set against the interior of the east wall, a compact construction roughly a metre and a half long and just under a metre high, built without mortar in the manner common to vernacular religious structures across Munster.

The building of a chapel inside a ringfort is itself a telling detail. Ringforts, the circular enclosed farmsteads of early medieval Ireland, were already ancient when Christianity was spreading across the country, and sacred sites were often deliberately established within or beside them, either to repurpose their spiritual associations or simply because the enclosure offered a ready-made boundary. By the time the first Ordnance Survey six-inch maps were being produced in 1842, this structure was already recorded as a Roman Catholic chapel in ruins, suggesting it had fallen out of active use well before that point. The rectangular plan, aligned roughly east to west as was conventional for Christian worship, measures just under ten metres in length and a little over six metres wide, placing it at the smaller end of what might be called a penal chapel or a simple rural mass house, the informal places of Catholic worship that became widespread during periods of religious restriction in Ireland.
