Whether it was already reduced to a faint trace in the landscape or had been absorbed into agricultural ground is unclear, but the site endured in a form that would not become visible again until 1987, when the discovery of a souterrain brought it back into the record.

A souterrain is an underground stone-built passage or chamber, typically associated with early medieval settlement in Ireland, sometimes used for storage, refuge, or both. The one uncovered here was sub-rectangular in plan, constructed of small stones and capped by large horizontal slabs. Inside, the excavation led by Mary Cahill of the National Museum of Ireland revealed the fully extended skeleton of a woman, lying on an east-west orientation with her head to the west, the conventional Christian alignment of the period. Near the upper right side of the skeleton was a small spread of charcoal. Radiocarbon dating subsequently placed the burial in the tenth century, situating this woman firmly within the early medieval period, roughly contemporaneous with the consolidation of Christianity in rural Munster and the disruptions of the Viking age. The use of a souterrain as a burial context is relatively unusual; these structures were built for the living, and finding one repurposed, or perhaps simply convenient, as a grave gives the site a quietly anomalous character that no amount of cartographic erasure has entirely concealed.
