The name "Cyclopean" refers to a style of masonry built with very large, irregular stones, and while the wall here is now low and tumbled, the circuit it once traced extended roughly 73 metres on a north-west to south-east axis. What makes this particular enclosure quietly unusual is that nature appears to have done some of the architectural work: from the south and south-west, a natural limestone scarp serves to define and overlook the interior, folding the surrounding karst landscape into the boundary itself rather than relying solely on built stone.

The enclosure belongs to a cluster of early Christian remains in this part of the island, sited about 180 metres south-east of Teampall Mac Duagh, a church associated with the sixth-century saint Colman mac Duagh. Near the centre of the enclosure stands Teampall na Naomh, the Church of the Saints, suggesting that this was not a marginal or secondary site but a deliberately organised sacred precinct with internal subdivisions, traces of which are still visible at the eastern side. An outer revetment, a facing of stone used to stabilise and retain the wall, can also be detected on the eastern edge, hinting at a structure that was once more formally constructed than its present ruinous state suggests. The site is referenced in O'Flanagan's early twentieth-century survey and in Tim Robinson's 1980 work on the Aran Islands, both of which recognised its significance even as so little of it remained legible above ground.

Visitors approaching from Port Mhuirbhigh will find the remains on level ground, though the collapsed wall blends easily into the broader limestone landscape and demands a slow, attentive eye. The natural scarp to the south is perhaps the most immediately readable feature, its rock face rising just enough to give a sense of the enclosure's original spatial logic.
