It is a souterrain, a type of artificial underground structure built during the early medieval period in Ireland, typically consisting of one or more corbelled or lintelled chambers connected by low crawlways. Their precise purposes are still debated among archaeologists, though they are generally thought to have served as places of refuge, cool storage for dairy produce, or both. Kerry has a notable concentration of them, which is not surprising given the density of early Christian settlement across the peninsula landscapes of the southwest.

Beyond its classification and location, the details of this particular example remain sparse. No dimensions, construction date, associated finds, or excavation history are currently available in the public record, which places it among a category of monuments that are known to exist but not yet fully documented or studied. That absence is itself telling. Many souterrains across Ireland were discovered incidentally, through agricultural work or land drainage, and a significant number have never been formally excavated. Some retain their original lintels and side walls intact; others have partially collapsed or been disturbed over centuries of farming. Without further investigation, it is difficult to say where the Ballymakegoge example sits on that spectrum.
