Ringfort (Cashel), Claggan, Dunfanaghy, Co. Donegal
This circular stone cashel in Claggan, County Donegal, sits atop a hill in what was clearly chosen as a defensive position.
Ringfort (Cashel), Claggan, Dunfanaghy, Co. Donegal
The structure measures approximately 14 metres north to south and 12 metres east to west, enclosed by a collapsed stone wall that was originally about 1.5 metres wide. The builders cleverly incorporated natural rock outcrops into the wall construction, blending human engineering with the existing landscape.
The site reveals interesting architectural features that hint at its complex design. About 2 metres below the cashel’s northern side, an arc of stones set on edge runs parallel to the main wall, curving concentrically before merging with rock outcrops at both ends. This creates a distinctive D-shaped level area measuring roughly 20 metres north to south, bounded on its northern edge by a sheer cliff face where remnants of a drystone wall still stand just inside the precipice.
Today, rough pasture covers most of the hilltop, though the D-shaped area notably retains good grazing land; a detail that suggests this space may have served a practical agricultural purpose even in ancient times. The cashel represents a type of ringfort common throughout Ireland, where stone was the preferred building material in rocky upland areas, as opposed to the earthen banks used in lowland regions.
