The main feature is a subcircular stone-walled enclosure measuring 18.3 metres in diameter internally, with walls that were originally about 1.4 metres thick. You can still see sections of the original wall facing both inside and outside the enclosure, and there’s a 2.3-metre gap on the southern side that likely served as the entrance. A curious semicircular kink in the eastern wall appears to be an original architectural feature rather than later damage.

Inside this ancient enclosure stand the ruins of St. Columbkille’s Chapel, a small stone church measuring roughly 5.75 metres by 3.4 metres internally. The walls, built from mortared slab stones with carefully cut corner stones, are about 75 centimetres thick, with the best-preserved quoins visible at the northeast corner. The main doorway sits centrally in the east wall, surrounded by several reused cut stones. In the northeast corner of the church lies what’s known as St. Columbkille’s Bed; two horizontal stone slabs bordered on the south by three upright stones. Above this ‘bed’, a small alcove has been carved into the east wall, measuring 35 by 20 centimetres and extending 35 centimetres deep into the wall. This alcove plays a role in the traditional turas, or pilgrimage circuit, associated with St. Columbkille.

The site contains several cairns topped with cross-inscribed slabs, adding to its religious significance. A cairn in the southeast, measuring 4.3 by 2.9 metres and standing 85 centimetres high, supports two cross-slabs; one stands 72 centimetres tall with faint geometric designs between its arms, whilst another smaller slab bears a cross and possible additional motifs. To the northeast, another cairn supports a slab inscribed with a simple cross on its western face. Perhaps most intriguing is a mound outside the enclosure to the east-southeast, topped with a large natural boulder known as Leac Na mBonn, or ‘flagstone of the footsoles’. This stone bears a distinctive carved cross enclosed within a circle, with the arms extending just beyond the circumference to end in T-shaped terminals, a design that speaks to the sophisticated stone-carving traditions of early medieval Ireland.
