Locally it goes by Kelly's Fort, a designation recorded as far back as 1914, when Neary noted it in the literature. That borrowed surname is a reminder of how vernacular memory works: a feature thousands of years old quietly acquires the name of a more recent family, and the older story recedes.

The structure itself is a rath, the most common type of ringfort in Ireland, typically a farmstead enclosed by earthen banks during the early medieval period, roughly between the fifth and twelfth centuries. This one measures thirty-one metres in diameter and is defined by two concentric banks with a fosse between them, the fosse being the external ditch dug to provide material for the banks and to add a further line of defence. The inner bank survives well along the western to northern arc and at the south-east, though elsewhere the enclosure is marked by a scarp, a slope in the ground rather than a raised bank, suggesting some erosion or later disturbance over the centuries. The outer bank and fosse hold up better, running from the south-west through north to north-east, though part of the outer bank has been absorbed into a later field boundary, the kind of quiet overwriting that happened across the Irish landscape as farming patterns shifted in the post-medieval period.

At thirty-one metres across, this is a modestly sized example, consistent with a single household enclosure rather than a high-status site with multiple rings of defence. Two-bank raths are somewhat less common than single-bank examples, which gives this one a mild distinction within the broader type. The outer bank surviving in reasonable condition means the original double-enclosure plan is still legible on the ground, even where modern field boundaries have complicated the picture.
