What makes it quietly remarkable is the precision with which its disappearance can be traced across successive maps, each one recording a little less of what was once there.

The 1842 Ordnance Survey map shows a circular enclosure positioned in the corner of a field, its boundary already compromised by a fieldbank cutting across the eastern side and another running along the northwest. Within that enclosure, a feature is marked simply as "Cave", which in nineteenth-century mapping convention typically indicates a souterrain, an underground stone-lined passage or chamber built during the early medieval period, often associated with nearby ringforts and used for storage or as a place of refuge. By the time the 1916 OS map was produced, only a tiny arc of the enclosure survived, visible along the western to southern edge. Today, nothing remains on the surface at all. The fieldbanks, the enclosure, and the underground passage have all been absorbed into the working landscape around them. Caroline Toal's North Kerry Archaeological Survey, published in 1995, recorded the site in this condition, drawing on what the maps could still tell rather than what the ground could show.
