A small gap between its roofing slabs is the only visible sign of what sits below: a souterrain, the name given to the kind of underground stone-lined tunnel or chamber that early medieval communities in Ireland built for storage, refuge, or some combination of both. This one is drystone-built, meaning its walls were laid without mortar, and the visible section of its passage runs roughly north-northeast to south-southwest, measuring at least two metres in length, though it is not currently accessible.

The place-name Na Leadhba Liatha locates the site within the broader landscape of the Iveragh Peninsula, a part of Kerry with a dense archaeological record reaching back through the early medieval period and beyond. Souterrains were typically associated with ringforts or early settlement sites, and their construction involved considerable effort, suggesting they served an important function for the communities that built them. Whether this particular example was attached to a nearby settlement feature is not recorded, and its absence from mapping makes its history harder to trace. What is known comes from fieldwork compiled by A. O'Sullivan and J. Sheehan for their survey of the Iveragh Peninsula, published by Cork University Press in 1996.

The site sits in rough pasture and the interior cannot be entered, but the gap between the roofing slabs does allow a partial view down into the passage. That narrow aperture is, in practical terms, the entire encounter on offer, which makes the place more curious than convenient, a small irregularity in a field that most people would walk past without a second glance.
