It is 1.75 metres wide and 0.6 metres high, sitting in the interior of an earthwork that has been here for well over a thousand years, and its purpose remains genuinely unknown. That unresolved quality is part of what makes the site worth thinking about: not everything old has been catalogued and interpreted.

The enclosure itself is a univallate rath, meaning a ringfort enclosed by a single earthen bank, a form of defended or semi-defended farmstead common across Ireland from the early medieval period, roughly the fifth to the twelfth centuries. This one has an internal diameter of approximately 26.5 metres and sits on a slope commanding a view over the entrance to Glenfais and the coastal plain bordering Tralee Bay. The enclosing bank varies considerably depending on whether you are measuring upslope or downslope: internally it stands about 1.1 metres on the uphill side and only 0.2 metres on the lower side, a disparity explained by the gradient of the ground rather than any deterioration. Externally the bank ranges from 0.35 to 1.3 metres in height and is 2.8 metres wide at its base. A three-metre entrance gap faces east-southeast. Beneath the dense vegetation that now covers much of the bank, partial clearance has revealed that sections of both the inner and outer faces were originally revetted with drystone masonry, a construction technique that lent structural stability to what might otherwise appear to be a simple earthen mound. The site was surveyed and documented by J. Cuppage as part of the Corca Dhuibhne archaeological survey of the Dingle Peninsula, published in 1986.

The dense overgrowth that obscures much of the interior is not merely an inconvenience for the casual observer; it is also the reason the site retains so much uncertainty. Other stone features were noted during survey but could not be properly examined. The L-shaped structure remains the only clearly legible element inside the enclosure, and whether it represents a later insertion, a structural remnant from the original occupation, or something else entirely is a question the vegetation has so far declined to answer.
