The southern half of the bank has vanished entirely, its absence noted but unexplained, while the northern arc survives in a condition that is dense with vegetation and easy to overlook. The whole structure measures only about ten metres across internally, modest even by the standards of small early enclosures, which in an Irish context were commonly used as farmsteads, burial grounds, or ecclesiastical precincts.

The townland name, Cill Fhiontain, points to an early ecclesiastical connection. "Cill" is the Irish word for church or monastic cell, and its presence in a placename is generally a reliable indicator that some form of early Christian activity took place nearby, even where no visible structure survives. The enclosure itself sits in level, low-lying ground, which is an unusual choice for a site of this kind; most comparable enclosures in Kerry occupy more defensible or drier positions. Where the bank does survive, along the northern half, it is composed of both earth and stone, rising to between 0.75 and one metre above the interior ground surface, and roughly two metres wide at its base. The second edition of the Ordnance Survey map recorded the full circuit, which means the southern bank was still present, or at least traceable, at the time that survey was carried out, and has been lost to land improvement or gradual erosion since.
