Levelled at some point before living memory, it survives only as a ghost in the landscape, detectable from the air but invisible underfoot. What was once a circular enclosure, the kind of roughly bounded settlement common across early medieval Ireland, has been reduced to a faint impression that only aerial photography can reliably read.

The site was recorded on Ordnance Survey maps of both 1842 and 1897, which means it was still legible as a feature on the ground, or at least as a boundary, well into the Victorian period. By the time the Air Corps flew photographic surveys in 1949, the enclosure had been levelled, yet the cropmarks and soil differences remained visible from altitude. As recently as 1991 it could still be detected from the air. More intriguing is a discolouration visible at the centre of the site, which archaeologists have interpreted as potentially indicating house-sites or souterrains beneath the surface. A souterrain is an underground stone-lined passage or chamber, typically associated with early medieval settlement in Ireland and used variously for storage, refuge, or both. The Kerry Field Club noted a tradition of souterrains in this vicinity as far back as 1948, and a related souterrain has been separately recorded nearby, suggesting the Rahoneen enclosure may be part of a denser pattern of early occupation in the area than the bare surface now implies.
