This circular earthwork, measuring 24 metres in diameter, sits just below the hill’s crest amidst rough pasture. What remains today is a raised platform that stands 2.25 metres high on its northern side, though it slopes dramatically down to just 10 centimetres on the southern edge; a testament to centuries of erosion and the natural contours of the hillside.

The site, marked as ‘Fort’ on the first edition Ordnance Survey six-inch map, has suffered considerable disturbance over the years. Now heavily overgrown with vegetation, it requires a keen eye to appreciate its original form and purpose. These ringforts, known locally as raths, were once common throughout the Irish countryside, serving as fortified homesteads for farming families during the early medieval period, roughly from the 5th to 12th centuries.

Despite its current state, this Revlin ringfort represents an important piece of Donegal’s archaeological heritage. The site was documented in the comprehensive Archaeological Survey of County Donegal in 1983, which catalogued field antiquities from the Mesolithic period through to the 17th century. While nature has reclaimed much of the structure, the earthwork continues to mark the landscape, a subtle reminder of the generations who once called this hillside home.
