This subcircular enclosure, measuring 18.3 metres in diameter, features walls that were originally 1.4 metres thick, with facing stones still visible on both the internal and external surfaces. A gap in the southern section provides entry, whilst a peculiar semicircular kink in the eastern wall appears to be an original architectural feature rather than later damage.

At the heart of this sacred site lie the ruins of St. Columbkille’s Chapel, a modest stone structure measuring 5.75 metres north to south and 3.4 metres east to west internally. The walls, constructed from mortared slab stones with ashlar quoins that survive particularly well at the northeast corner, stand 0.75 metres thick. The chapel’s eastern wall contains a centrally placed doorway surrounded by rebuilt cut stones, and in the northeast corner sits a curious feature known as St. Columbkille’s Bed; two horizontal slabs bounded on the south by three side stones. Above this ‘bed’, a small alcove has been carved into the eastern wall, measuring 35 by 20 centimetres and extending 35 centimetres deep, which plays a role in the traditional turas, or pilgrimage circuit, associated with St. Columbkille.

The enclosure contains several cairns topped with inscribed cross slabs, testament to the site’s long history as a place of devotion. The largest cairn, positioned against the southeast interior of the enclosure wall, rises 0.85 metres and bears two cross slabs; one stands 72 centimetres high with faint geometric designs between its arms, whilst a smaller slab displays an inscribed cross alongside other possible motifs. Additional cairns scattered throughout the enclosure also bear cross slabs, including one to the northeast topped with a stone showing a simple incised cross on its western face. Outside the enclosure to the east sits a distinctive mound crowned by a natural erratic boulder known as Leac Na mBonn, or ‘flagstone of the footsoles’. This stone bears a carefully inscribed cross within a circle, its shafts extending beyond the circumference to terminate in T-bars, marking another station in the ancient pilgrimage route through this atmospheric site.
