A roughly circular enclosure, about 24 metres across, once occupied the high ground above the Ballymeeny river, which runs northward through the ravine below before reaching the sea. The bank that defined the enclosure has been so thoroughly levelled that it survives now only as a slight rise in the grass, curving from the south-west to the north-west, and fading at its northern end into a barely perceptible undulation, or in dry conditions, a cropmark, the kind of ghost-image that appears in parched grass when buried features draw moisture unevenly from the soil.

The enclosure does not appear on the six-inch Ordnance Survey map of 1837, suggesting either that it was already too degraded to record or that the surveyors of the time simply passed over it. By the 1913 edition, however, it is marked as a semi-circular hachured area, with its southern edge defined by a field boundary that may itself have been shaped by, or overlaid on, the older feature. Circular and sub-circular enclosures of this kind are common across Ireland, and while their origins vary, many are associated with early medieval settlement, enclosing a farmstead or house-site within a bank and sometimes a ditch. What is less common here is the relationship with the landscape immediately below. At the south-eastern edge, where the enclosing bank meets a natural break of slope, the ground drops away into the ravine in a way that allows relatively easy descent. Roughly 15 metres down that slope sits a natural spring, also recorded as a holy well, its presence suggesting that whoever chose this ridge-top location did so with an awareness of what lay beneath as much as what could be seen from above.
