That combination, a substantial earthen rampart enclosing an area the size of a small field, signals something more deliberate and more ancient than a simple pastoral boundary.

The enclosure is defined by an earthen bank with an internal fosse, meaning the ditch runs on the inside of the bank rather than the outside, a detail that raises questions about the site's original purpose. Whether it was ceremonial, territorial, or connected to burial practice is not fully resolved. The bank remains largely intact on the south-west and north-west to north sides, though it has been levelled on the north-east to south arc, and a later stone field boundary has been built directly over it on the southern side. That the enclosing element was still shown intact on the first edition Ordnance Survey map of 1838 suggests it was a recognisable feature of the landscape well into the modern period. Inside the enclosure, the site becomes more layered still: a cairn, which is a mound of stones typically associated with prehistoric burial or commemoration, sits within the interior, along with what may be a standing stone, roughly 0.6 metres high, positioned near the south-west section of the bank. Old field walls also thread through the interior, evidence that the land was worked and subdivided at some point, without any apparent awareness of, or concern for, what lay beneath the surface arrangement.

The site was documented in D. Lavelle's 1994 archaeological survey of the Ballinrobe district, which covered the broader landscape around Lough Mask and Lough Carra. That survey drew attention to a cluster of monuments in this part of Mayo that rarely feature in wider accounts of Irish prehistory, and this hilltop enclosure is among the more quietly compelling of them.
