This is a rath, the Irish term for a ringfort, a type of enclosed farmstead typically dating from the early medieval period, roughly 500 to 1000 AD, built by a single family or small community as a combination of homestead and livestock enclosure. What makes this one quietly interesting is the layering visible in its structure: it has not simply decayed but has been actively reworked, its ancient earthen banks cut through, faced with stone, and then supplemented again with a later enclosing element of earth and stone piled on top.

The enclosure measures approximately 24 metres in diameter, defined by a scarp, essentially a shaped earthen slope or bank, that survives to only about 0.1 metres in height at the north and north-east but rises to 1.25 metres along the southern arc. That southern stretch is also the best-preserved section, where the original scarp has been faced with a dry stone wall, now largely hidden beneath briars and grass. The western and eastern arcs have been cut through entirely and rebuilt as straight linear stone walls, suggesting the site was at some point pressed into service as ordinary agricultural enclosure. Traces of the earlier earthen bank remain near the ends of those walls, hinting at what once existed. A more recent addition of earth and stone runs along much of the present perimeter, overgrown and broken in several places. The interior shows a small central depression and faint traces of cultivation. Trees have taken hold around the northern half. The rath was first formally identified by Myler in 1998, though the landscape it overlooks, across the valley towards Mullaghmesha, would have made it an obvious spot for settlement long before anyone thought to record it.
