The structure is a cashel, a type of ringfort built from dry-stone walling rather than earthen banks, and this one measures around 37 metres in diameter. What makes it particularly curious is how thoroughly the landscape has assimilated it: the original wall survives only along a partial arc running from west-northwest through north to south-southeast, and a curving field wall to the west may simply be the old cashel wall pressed into agricultural service at some point over the intervening centuries.

Recorded by McCaffrey in 1952, the site was already poorly preserved by that point, suggesting a long history of gradual disturbance. Modern field walls cut across the monument at two points to the south, slicing through what was once a continuous enclosure. Inside the cashel, a collapsed curving bank hints at an internal division, which would not be unusual; some cashels contained subdivided interiors used for separating livestock or demarcating different functional areas within the settlement. Cashels as a class date broadly to the early medieval period, roughly the fifth to twelfth centuries, and functioned as enclosed farmsteads, their stone walls serving both a practical and a social role in a landscape where such enclosures signalled status and ownership.
