The site consists of a subcircular stone enclosure, approximately 18.3 metres in diameter, with walls that were originally 1.4 metres thick. Both internal and external wall facings remain visible, and there’s a distinctive semicircular kink in the eastern section that appears to be an original architectural feature. A gap of 2.3 metres on the southern side provides access to this ancient sacred space.

At the heart of the enclosure lie the ruins of St Columbkille’s Chapel, a modest structure measuring 5.75 metres north to south and 3.4 metres east to west internally. The mortared slab stone walls, three quarters of a metre thick, feature ashlar quoins that have survived particularly well on the northeast corner. The centrally placed eastern doorway incorporates several cut stones that have been rebuilt into the surrounding wall. In the northeast corner, visitors can find St Columbkille’s Bed; two horizontal slabs bounded on the south by three side stones, with a small alcove above it in the eastern wall. This alcove, measuring 35 by 20 centimetres and 35 centimetres deep, plays a role in the traditional turas, or pilgrimage rounds, associated with the saint.

The enclosure also contains three cairns topped with cross slabs, each displaying early Christian carved symbols. The southeastern cairn supports two cross slabs, one bearing a geometric design between its arms and another inscribed with a cross and possible additional motifs. The northeastern cairn features a slab with a simple incised cross on its western face, whilst a third cairn to the south stands without any cross slab. Perhaps most intriguing is a mound abutting the outer edge of the enclosure to the east southeast, topped with a large natural erratic known as Leac Na mBonn, or ‘flagstone of the footsoles’. This stone bears an inscribed cross within a circle, with the cross’s shafts extending just beyond the circumference to end in T bars, alongside what may be a shallow cupmark on its surface.
