These sites occupy a peculiar and melancholy corner of the Irish landscape, neither fully sacred nor entirely secular, and the one at Cinn Aird Thoir follows a pattern found across the country: quietly set apart, overlooking water, and long since fallen out of use.

The enclosure measures roughly 19 metres north to south and 17.5 metres east to west internally, enclosed by a sod-covered bank of earth and stone that still stands to a maximum external height of 1.15 metres on its eastern side. Stretches of drystone facing, a technique in which stones are stacked without mortar, survive along the inner western flank, though sections of the northern bank have been levelled over time. Inside, the ground is crowded with loose stone, quartz blocks, and upright slabs, most of them concentrated in the western half and arranged in rough east to west rows. Several low, shapeless mounds are also visible. The arrangement suggests deliberate, if modest, grave-marking, the quartz blocks in particular being a material associated with burial across many periods of Irish prehistory and early Christianity. By the late nineteenth century, the site had ceased to function as a burial ground, leaving only the stones and the mounds to indicate what had taken place within the bank.
