Within it sit at least three stone-constructed mounds, and nobody is entirely certain what they represent. The leading candidates are a souterrain, an underground stone-lined passage or chamber built in early medieval Ireland typically for storage or refuge, and the remains of house-sites. That ambiguity is itself the most interesting thing about the place: it has been noticed, mapped, and recorded, yet it has not quite been solved.

The site was documented as part of C. Toal's North Kerry Archaeological Survey, published in 1995, which catalogued the remarkable concentration of early remains across this part of the county. The enclosing earthen bank points toward a settlement context, and the stone mounds in the interior are consistent with what survives above ground when a souterrain collapses or silts up over centuries. Souterrains are found widely across Ireland, often associated with ringforts, and their entrances and passages can become so degraded that what remains looks, on the surface, more like rubble than architecture. Whether these particular mounds represent that kind of structural collapse, or something older and more domestic, has not been firmly established.
