This stone fortification, built from large blocks carefully placed along both inner and outer edges, once formed part of a circular enclosure typical of early medieval Irish settlements. Today, roughly 25 metres of the eastern section survives, its 1.2-metre-wide construction still visible despite centuries of deterioration and the intrusion of a modern field wall that cuts north to south through the historic structure.

The cashel has suffered considerable damage over time, with gaps appearing where the modern wall crosses and another breach near the southern end where disturbance has taken its toll. A pile of stones further south appears to follow the original wall's trajectory, suggesting the cashel once extended much further. These ring-forts, known locally as cashels when built of stone rather than earth, served as defended homesteads for farming families from roughly the 5th to 12th centuries AD.

The location was clearly chosen with care; the elevated position offers commanding views across the surrounding countryside whilst providing excellent grazing land, both essential considerations for early medieval inhabitants. This particular site was documented in the Archaeological Survey of County Donegal, compiled by Brian Lacey and colleagues in 1983, which catalogued field antiquities spanning from the Mesolithic period through to the 17th century. Like many of Donegal's archaeological sites, this cashel stands as a subtle reminder of Ireland's layered history, its stones quietly marking a place where people once lived, farmed, and watched over their lands.
