The site is known as Lisroe, or Lios Rua, meaning russet ringfort, a name that may reflect the reddish quality of the soil or stonework. What makes it quietly interesting is not just the earthwork itself but what survives inside it: the traces of a stone structure and, possibly, a concealed underground passage that nobody has yet confirmed or fully excavated.

The ringfort is a univallate rath, meaning it has a single enclosing bank with an exterior fosse, or ditch, running around its outer edge. The interior sits at a noticeably higher level than the surrounding land, and two entrances break the bank, one to the north at roughly five metres wide and a narrower one to the south-south-west at around three metres. In the south-western to western part of the interior, an oblong stone enclosure measuring approximately six by seventeen metres externally, with walls about a metre thick, has been identified as a possible house-site. Immediately to the west of this lies a small stone-laden mound, only about one and a half by three and a half metres internally, which archaeologists have flagged as a possible souterrain. Souterrains are stone-lined underground passages or chambers associated with early medieval settlement in Ireland, typically used for storage or as refuges. The tentative language here is deliberate; neither the house nor the souterrain has been confirmed through excavation, and both remain educated observations rather than established facts. The description was recorded by C. Toal in the North Kerry Archaeological Survey, published in 1995.
