Sitting on a gentle natural rise in County Westmeath, it commands good views across the surrounding grassland in every direction, yet there is little left of it that would catch the eye of a casual passer-by. The earthen bank that once enclosed the site has been worn down and broken in several places, and the shallow ditch, or fosse, that ran around its outer edge is almost entirely filled in. What survives is a roughly circular enclosure about thirty-two metres across from north to south, the kind of modest domestic ringfort, an enclosed farmstead typically occupied during the early medieval period, that would once have been a commonplace feature of the Irish countryside.

Inside the enclosure, faint traces of cultivation ridges run diagonally across the interior from northeast to southwest, suggesting that the site was later put to agricultural use, which accounts for some of the disturbance to the bank. A field fence erected after 1837 cuts along just outside the southwestern edge, a reminder of how successive generations of landowners reorganised the landscape around monuments they had no particular reason to preserve. A second ringfort lies roughly 160 metres to the northeast, making Rathganny something of a minor cluster, though whether the two were ever occupied simultaneously or represent different phases of settlement is not recorded here. What remains is an archaeological outline rather than a dramatic ruin, the kind of site that repays a slow look across the ground surface rather than any expectation of standing walls or clear boundaries.
