This is a rath, a type of ringfort built during the early medieval period, typically between the sixth and tenth centuries, as an enclosed farmstead for a single family or small community. What makes this one quietly arresting is not any dramatic monument but the way the landscape has gradually absorbed and adapted it: the ditch that once defined its outer edge has been partly filled in and pressed into service as a forest road, while the interior is colonised by coniferous trees planted well after the fort's original purpose had long been forgotten.

The enclosure is roughly circular, measuring approximately 38 metres east to west and 33 metres north to south. It is defined by an earthen bank that still stands 1.7 metres high on the interior face and around 0.7 metres on the exterior, with an external fosse, or ditch, reaching a depth of 1.3 metres where it remains intact. The entrance, a causewayed gap left uncut across the fosse, faces east and is about four metres wide, which is typical of the form; east-facing entrances are common in Irish ringforts. On the north side, the interior has been deliberately raised to compensate for the natural slope of the hill, a detail that speaks to the care and calculation that went into even modestly scaled constructions of this kind. The site sits on a north-north-east-facing slope, and the surrounding Philip's Wood, now in maturity, wraps it in near-total shade.

The fosse to the north-east, infilled at some point and converted into a forest track, is one of those small, telling details that accumulates meaning over time: a boundary ditch that once marked social and agricultural territory quietly becoming infrastructure for a plantation that postdates it by perhaps a thousand years. The coniferous planting within the enclosure itself means that from ground level the internal space is as crowded as the surrounding woodland, though the bank and ditch profile remain legible to anyone moving slowly around the perimeter.
