Rather than relying solely on human construction, whoever built this structure let cliffs and rock scarps do much of the work along the northern and north-western sides, while the river closes off the southern edge entirely. Only the south-western, north-western, and south-eastern stretches required a hand-built wall, and that wall, now collapsed, survives as a low drystone ridge rarely more than half a metre high.

The enclosure is irregular in shape, stretching roughly 135 metres on its longer north-west to south-east axis and about 47 metres across at its widest. Drystone construction, which involves stacking stones without mortar and relies on careful selection and placement for stability, was a common technique across early Irish settlement and farming enclosures. What makes this particular example quietly strange is how thoroughly the natural terrain has absorbed it. The lower courses of the south-eastern wall have sunk into deep bog, effectively swallowed by centuries of peat accumulation, and the interior of the enclosure slopes downward toward the south-east, following the natural fall of the hillside. The site sits in rough pasture on a south-east facing slope, a setting that would have offered reasonable shelter and some solar exposure, though no date or period of construction has been established for it.
