The cashel, a type of stone ringfort common throughout Ireland, occupies a dramatic position with steep drops to the north and northwest towards the lough below, whilst a hillside rises sharply to the east. Though heavily overgrown and partially ruined, careful observation reveals the outer wall face running intermittently from north;northwest to southeast, constructed from large stones set on edge around the platform’s upper rim.

The interior remains relatively level despite some protruding bedrock, suggesting it once provided a defendable living space for an early medieval farming family. Today, the southeastern and southern sections of the original cashel wall have been incorporated into a later field boundary, a common fate for many ancient monuments as they were repurposed by subsequent generations. The surrounding landscape tells its own story of marginal agriculture; whilst the immediate vicinity offers only poor grazing, the land improves notably to the west, perhaps explaining why this elevated, defensive position was chosen despite its exposed location.

This modest but evocative site appears on the third edition Ordnance Survey 6;inch map as ‘Cashelnahunalta’, preserving its Irish place name which likely references the cashel itself. Like many such monuments scattered across Donegal’s rugged terrain, it stands as a testament to the resourcefulness of Ireland’s early medieval inhabitants, who built their homes in stone on these windswept heights, balancing the need for defence with access to grazing lands and water sources.
