What was once a roughly circular earthwork, some thirty metres across, has been worn down to the point where much of it blends almost seamlessly into the surrounding field. Only the south-western arc still holds its shape clearly. The rest is a matter of reading subtle gradients, shallow depressions, and the way the land lifts almost imperceptibly beneath your feet.

This is, or was, a rath, the most common form of early medieval enclosure in Ireland. Typically earthen, sometimes reveted with stone, a rath would have enclosed a farmstead and its associated buildings, with a bank and external ditch, known as a fosse, marking the boundary. The fosse here is tentative at best: a depression no more than ten centimetres deep on the south-south-west side, another shallow trace on the west, both too faint to read with certainty. A report from 1991 captured the site in better condition, noting a scarp still standing a metre high along the southern half, with the northern perimeter already fading into the field around it. By 2006, ground works had levelled part of the site further, shifting its outline from roughly circular to something closer to a D-shape, measuring around thirty-three metres on its longer axis. Ballysadare Bay lies about three hundred metres to the south, with a marshy peninsula reaching out into the water just a hundred metres beyond the field's edge, a detail that suggests whoever originally chose this position was attentive to both land and water.
