It only revealed itself clearly when viewed from the air, in photographs taken in 1987, where its outline resolves into an unusual pear shape. On the ground, it is nearly invisible, absorbed into the surrounding landscape and cut through on its southern and eastern sides by later fieldbanks, the low earthen or stone boundaries that divide agricultural land across Ireland. What remains measures 37.6 metres north to south and rises no more than 0.6 metres above the surrounding terrain, which is part of why it escaped cartographic notice for so long.

Enclosures of this kind, roughly circular or oval earthworks defined by a bank and sometimes a ditch, are among the most common early medieval monument types in Ireland, though most are associated with settlement or ritual use dating from roughly the fifth to the twelfth centuries. What makes this one of particular interest is not its scale or condition but its geometry. The pear shape is irregular enough to stand apart from the typical ring-fort or rath, and the partial destruction caused by later field boundaries means its original dimensions can only be approximated. The site was documented by Caroline Toal in the North Kerry Archaeological Survey, published in 1995 by Brandon in association with FÁS, which catalogued a wide range of monuments across a part of the country that had received relatively little systematic archaeological attention.
