It is not marked on any historic Ordnance Survey map. It leaves no impression on aerial photographs. To all practical purposes, it has vanished, and yet surveyors who visited in 2007 recorded it carefully, measuring a circular area just 3.2 metres in diameter, ringed by a shallow scarp, a fosse, and a low outer bank. The fosse, a narrow ditched depression, is only about ten centimetres deep; the outer bank barely registers above the surrounding ground. What you have, in other words, is the ghost of a small round hut, detectable only at close range and with some patience.

The site sits within the north-western interior of a ringfort, the enclosure recorded as LI033-014. Ringforts, the circular farmstead enclosures that dot the Irish countryside in their thousands, were most commonly occupied during the early medieval period, roughly the fifth to twelfth centuries, and it was not unusual for one or more smaller structures to occupy the interior alongside the main dwelling. This hut, modest even by the standards of such ancillary buildings, lies roughly 550 metres east of the hill summit, which reaches about 580 feet above sea level, and approximately 100 metres south of the townland boundary with Ballyvouden. Its absence from the historic Ordnance Survey mapping suggests it was already invisible to nineteenth-century surveyors, its features too subtle to be caught by conventional cartographic methods. It was the Archaeological Survey of Ireland that formally recorded it in 2007, the survey compiled by Martin Fitzpatrick and uploaded to the national record in April 2021.

Visitors approaching the area should be aware that there is genuinely very little to see on the ground. The scarp height is recorded at fifteen centimetres and the outer bank, at its most pronounced on the eastern to north-north-west arc, rises just forty centimetres on its exterior face. Low-angle morning or evening light in late autumn or winter, when vegetation is short and shadows are long, offers the best chance of distinguishing these earthworks from the surrounding pasture. The site is on private farmland, so permission from the landowner should be sought before approaching. The nearby ringfort itself, within whose boundary this hut sits, provides the broader context, and looking for both features together gives a clearer sense of how this small corner of a Limerick hillside was once organised and used.
