The site, which sat at the western edge of a low north-to-south ridge, was levelled at some point before anyone thought to preserve it. What remained was a memory of a saucer-shaped hollow, roughly ten to fifteen metres across, edged by a low bank of earth and stone. Locals knew it as 'an poll mór', meaning simply 'the big hole', a name that carries more weight than it might first seem, suggesting the site was distinctive enough to landmark in the local imagination long after its original purpose had been forgotten.

When the ground was cleared, those doing the work uncovered three or four large stones that had been positioned within the interior, hinting at some kind of deliberate arrangement, whether structural or ceremonial is now impossible to say. More revealing was the discovery of a midden, a deposit of discarded sea shells that accumulated over time as people processed or consumed shellfish on or near the site. Middens of this kind are known from prehistoric and early historic contexts across Ireland's coastline, and their presence here, on a low inland ridge within reach of the Atlantic, suggests sustained human activity over a considerable period. The shells point toward a community that was at least partly oriented toward the sea, exploiting its resources and leaving, without any intention of doing so, a compressed record of their diet and their presence.
