It is not immediately obvious what it was for. The structure is classified as a hut site, but the archaeologists who recorded it noted it may equally have served as an animal pen, which is a reminder of how blurred the line between human shelter and livestock management often was in early rural Ireland.

The enclosure is subcircular in plan, measuring roughly six metres north to south and five metres east to west internally. Its drystone wall, built without mortar by fitting stones carefully against one another, survives to around a metre in height and is between 1.2 and 1.4 metres thick, which is a substantial construction for something of this scale. A narrow entrance, just 0.6 metres wide, opens to the northwest. The site sits within a wider field system and is not isolated in the landscape. A cashel, which is a stone-walled ringfort typically associated with early medieval settlement and farmsteads, lies approximately 80 metres to the northwest, and a second cashel stood around 70 metres to the south, suggesting this part of the valley once supported a cluster of related activity rather than a single lonely structure. The site was identified from a Cambridge aerial photograph taken in 1970 and confirmed on Ordnance Survey orthophotography from 1995, meaning its existence in the documentary record is relatively recent even if the structure itself is far older.
