Bullaun stone, Doon Glebe, Co. Donegal
On the southern slopes of Glendoon Hill in County Donegal sits the remains of what appears to be a destroyed ringfort, a circular earthwork that once served as a fortified farmstead in early medieval Ireland.
Bullaun stone, Doon Glebe, Co. Donegal
The site consists of an almost circular platform, measuring roughly 30 metres across, surrounded by a wet ditch that still holds water today. A low field bank encircles most of the platform’s perimeter, and numerous stones are visible both in the ditch and along the platform’s edges, likely remnants of the original stone facing that would have reinforced the earthen banks.
The most intriguing feature lies just northeast of the platform’s centre: a large oval stone, partially buried in the earth, measuring 1.8 metres by 1.15 metres and rising only 10 to 20 centimetres above ground level. Its long axis runs north to south, suggesting deliberate placement rather than random deposition. Records from the National Museum of Ireland mention a bullaun stone; a rounded granite block with a depression cut into it, traditionally used for grinding grain or holding holy water; located at the southwest of the ringfort, though recent surveys haven’t been able to locate this particular artefact.
The ringfort’s strategic position offers commanding views across the surrounding landscape, and the land itself remains fertile, if somewhat waterlogged. Archaeological evidence suggests the southern side may have featured a double or stepped bank within the ditch, a defensive enhancement that would have made the settlement even more formidable. These ringforts typically date from the early medieval period (roughly 500 to 1200 CE) and served as the homes of prosperous farmers and their extended families, providing both security and status in a turbulent era.
