In the wet boglands of Lettershanbo in County Donegal sits a curious circular enclosure, its 18-metre diameter marked by the remnants of a collapsed stone wall now overgrown with heather.
Ringfort (Cashel), Lettershanbo (Cloghan Ed), Co. Donegal
This ringfort, or cashel as such structures are sometimes known in Ireland, represents one of thousands of similar defensive homesteads that once dotted the Irish landscape during the early medieval period. Today, only traces of its original form remain visible; the western section has deteriorated to little more than a raised arc beneath the vegetation, whilst rushes growing thick against what’s left of the wall suggest there may once have been a defensive ditch, or fosse, surrounding the structure.
The interior of the enclosure tells its own quiet story of abandonment. Where once a family might have kept livestock, stored grain, or sheltered within a dwelling, there’s now only level, featureless ground that betrays no hint of its former purpose. The site’s location on open, waterlogged bogland might seem an odd choice for settlement, but such spots often provided strategic advantages; the wet ground itself acted as a natural barrier to potential raiders, whilst the elevated position of the ringfort would have offered clear views across the surrounding landscape.
This particular site was documented as part of the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of researchers. Their work catalogued field antiquities spanning from the Mesolithic period through to the 17th century, preserving details of sites like this cashel that might otherwise be lost to time and the encroaching bog. Though modest in its current state, this circular enclosure stands as a tangible link to the rural communities who shaped this corner of Donegal over a millennium ago.
