This roughly circular earthwork, measuring about 30 metres across, occupies a strategic position on an east-west ridge amongst the rough, rocky terrain of the mountainside. The site makes clever use of the natural landscape for its defences; sheer cliff faces protect the eastern approach, whilst steep natural slopes guard the western side, and a rock outcrop forms a barrier to the south. Only the northern edge required human intervention, where the builders constructed a low earthen bank to complete the defensive circuit.

At the heart of this mountain stronghold lies a small rectangular feature, measuring just 1.7 metres north to south and 1.4 metres east to west. This central structure might represent the foundation of a small dwelling or storage building, though its exact purpose remains uncertain. The fort’s elevated position would have provided excellent views across the surrounding landscape, making it an ideal location for monitoring movement through the mountain passes whilst offering a defensible retreat for the local population during times of conflict.

This ringfort forms part of a broader pattern of early medieval settlement across Donegal, where such fortified farmsteads were typically built between the 5th and 12th centuries AD. The site’s documentation comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983, which catalogued field antiquities spanning from the Mesolithic period through to the 17th century. Today, visitors to this remote spot can still trace the outline of this ancient homestead, its earthworks and natural defences bearing witness to a time when security and strategic positioning were essential considerations for those who chose to make their lives in these rugged uplands.
