The ringfort, or rath, a type of enclosed farmstead typically built during the early medieval period in Ireland, now survives only in part: a curving arc of earthen bank, roughly 21 metres long, persisting on the south-east side of that intruding boundary. The bank rises about 1.3 metres on its outer face, considerably less on the inner, and its raised interior is overgrown, with tree stumps breaking the surface where planting has since come and gone.

The 1842 Ordnance Survey six-inch map records the full form of the enclosure as a hachured circle of approximately 30 metres in diameter, which gives a clearer sense of what once stood here before modern land use intervened. A researcher named Bowman, writing in 1934, noted a fort on what was then Mrs Faber's land in the area, describing it as having been levelled long since. Whether that refers to this same earthwork is uncertain, but it is plausible. The surviving bank has been planted with mature deciduous trees, suggesting the remnant was repurposed at some point as a tree ring, a common fate for partial earthworks that were too awkward to remove entirely but too reduced to be treated as anything more than a convenient windbreak or ornamental feature. The site sits on a south-facing slope roughly 100 metres north of the River Blackwater, within pasture ground that has continued to be worked around it.
