This subcircular cashel, measuring approximately 20 metres in internal diameter, features what appears to be an entrance on its southeastern side. The structure rests on a small plateau, its stones now weathered and partially concealed by centuries of vegetation growth, yet still discernible to those who know where to look.

The site gained renewed archaeological attention in 2007 when Caitríona Gleeson conducted pre-development testing just 50 metres to the south, ahead of construction for a new farmyard shed at Falduff, Carndonagh. Despite the proximity to this known cashel site, catalogued as DG011;058, the excavation of four test trenches revealed no archaeological materials or cultural layers predating the 20th century in the development area. This negative evidence is itself valuable, helping to define the boundaries of ancient activity and suggesting that the cashel stood somewhat isolated from other contemporary structures.

First documented in the Archaeological Survey of County Donegal in 1983, this cashel represents one of thousands of similar defensive homesteads that dotted the Irish landscape during the early medieval period. These stone;built enclosures, known locally as cashels or caiseal in Irish, served as fortified farmsteads for prosperous families, providing protection for both people and livestock. The thick stone walls would have originally stood much higher, possibly topped with timber palisades, creating a secure compound from which the surrounding lands could be farmed and managed.
