The enclosure is classified as a univallate cahir, meaning a stone-built ringfort defended by a single surrounding wall or bank, a form of settlement that appears widely across early medieval Ireland. What makes this particular example quietly puzzling is what lies inside: the raised interior sits at a noticeably higher level than the surrounding land, and the mounds distributed across it resist easy interpretation.

According to the North Kerry Archaeological Survey compiled by C. Toal and published in 1995, the interior contains at least three distinct mounds. In the western sector, an oblong mound runs roughly ten metres north to south and between one and two metres east to west. About two and a half metres to the east of this sits a second mound, three metres by two metres in plan and standing four metres high, making it a substantial feature by any measure. A third, smaller mound lies to the south-east of that. The surveyors noted that these mounds could represent house sites, the buried footprints of structures that once stood within the enclosure, or they could be souterrains, the stone-lined underground passages sometimes built beneath early Irish settlements for storage or refuge. A semi-circular bank in the south-east sector curves inward toward the main enclosing wall, adding another element that does not immediately resolve into a clear function. The date of the site remains indeterminate, and without excavation the mounds will likely keep their ambiguity.
