The first Ordnance Survey recorded it as a roughly circular earthwork, the classic shape of an early medieval rath, a circular enclosure of banked earth typically used as a farmstead or high-status dwelling from roughly the fifth to the twelfth century. By the time surveyors returned for the revised edition, the map showed something unrecognisable: a much-modified rectangular-shaped earthwork. Whatever occurred in those intervening decades reshaped, deliberately or otherwise, a monument that had likely held its original form for a thousand years or more.

When the site was formally described in 1980, it measured roughly 37.5 metres east-northeast to west-southwest and 34 metres north-northwest to south-southeast, encircled by an inner bank, an intervening fosse (a defensive ditch), and the partial remains of an outer bank, suggesting this was once a multivallate rath, a more elaborate and possibly higher-status enclosure than a simple single-banked example. A second ringfort lies approximately 90 metres to the northwest, hinting that this corner of Westmeath was once a more densely settled early medieval landscape than its current pasture fields suggest. The site sits on a gentle east-facing slope with broad views in most directions, a siting typical of ringforts, where visibility and drainage both mattered. What has done most damage since then is quarrying: a large depression has eaten into the perimeter from the southwest through to the northwest, and has swallowed much of the interior in those same quadrants. The inner bank survives best from the north-northeast around to the south, and a wide gap of about 5.5 metres in the bank at the east may mark the original entrance. The fosse remains fairly wide and deep in places, and the outer bank, though mostly gone, is still more substantial along the south-southeast arc, where it appears to have been modified at some point. A ring of trees, visible in aerial photography, now traces the surviving circuit of the earthwork.
