This circular enclosure, measuring approximately 35 metres in internal diameter, sits atop a drumlin where the land quality is notably better than the wet, boggy terrain that characterises much of the surrounding area. Today, only the southern section of the earthwork survives, but it's enough to reveal the original triple defence system: an inner earthen bank, a defensive ditch or fosse, and an outer bank that would have presented formidable obstacles to any would-be attackers.

The ringfort occupies rising ground to the north of a substantial stream, a position that would have offered both defensive advantages and access to water. The fosse, though now wide and heavily silted, still traces the curve of the original fortification, hinting at the considerable labour invested in its construction. Such ringforts, known locally as raths, were the predominant settlement type in early medieval Ireland, typically housing extended families and their livestock within the protected enclosure.

What makes this site particularly intriguing is its proximity to another ringfort, catalogued as DG100-009. This clustering of defended settlements suggests the area held particular significance, perhaps as good agricultural land worth protecting in an otherwise challenging landscape of bog and wetland. The survival of these earthworks, documented in the Archaeological Survey of County Donegal in 1983, provides tangible evidence of how our ancestors adapted to and modified the Irish landscape over a millennium ago.
