The enclosure, about 56 metres across at its widest point from northwest to southeast, is defined by straight sections of walling along its western and northern sides, with a gentle curve running from the northeast around to the southwest. The shape gives it away as something deliberate, something built rather than accumulated by chance, though the ground-level view offers little more than low, uneven ridges softened by decades of vegetation.

The enclosure sits within a much larger field system that extends along the Burren uplands between Poulbaun to the north and Rannagh West to the south. Field systems of this kind are a recurring feature of the Burren, where the limestone landscape preserved ancient agricultural boundaries that elsewhere were ploughed out or built over. Such systems could date from any number of periods, from the Bronze Age through to the medieval, and the enclosure itself, roughly D-shaped in plan, is a form associated with early settlement and farming across Ireland, sometimes serving as a farmstead boundary, sometimes as an enclosure for livestock. Without excavation, its precise age and function remain open questions. The site was noted by Ros Ó Maoldúin and identified through aerial imagery captured between 2012 and 2018, which made its outline visible in a way that ground survey alone might easily miss.
