That absence is, in its own way, the most interesting thing about the site.

A souterrain is a man-made underground passage or chamber, typically constructed during the early medieval period in Ireland, often used for storage or as a place of refuge. In the 1930s, a Capt. D.B. O'Connell recorded what he found at the base of a steep north-west-facing slope: a slight mound at the centre of a large field sloping down from a farmhouse, marked by two massive flagstones concealing what he described as extensive cavities beneath. The field sits within what may also be the outline of an enclosure, suggesting that whoever built and used the souterrain was part of a more organised settlement of the surrounding land. None of that is visible today. The flagstones are gone, the mound has levelled out, and the cavity, if it persists at all, lies quietly under the grass with no surface trace. A scatter of stones and rocks along the northern boundary is all that remains above ground to suggest anything of archaeological note was ever here.
