The structure is modest in scale, measuring just 2.6 metres east to west, with a straight western side running 4.4 metres. What makes it quietly odd is its form: most field enclosures are roughly circular or rectangular, but this one combines a curved arc with a deliberate flat edge, giving it a geometry that feels considered rather than incidental.

The enclosure is defined by a drystone wall, a construction technique relying entirely on dry-laid stones without mortar, which was common across Irish landscapes from prehistory well into the early modern period. The wall has largely collapsed, though it still stands to an internal height of 0.6 metres and 0.9 metres on the exterior face, suggesting the ground inside was cut or levelled slightly lower than the surrounding slope. A narrow entrance, just 0.6 metres wide, opens to the east. The interior itself slopes downward to the south, and a small boulder sits near its centre. Whether that boulder is incidental or ever served some structural or functional purpose is not recorded. The enclosure sits within a broader field system on the hillside, which places it in a landscape of accumulated agricultural effort rather than as an isolated curiosity.
