This circular fortification, measuring 37 metres across its interior, is defined by a remarkable stone wall that has largely survived the centuries. The best preserved sections of the original construction can be found along the northern and eastern sectors, as well as on the western side of what appears to be the main entrance; a three metre wide gap in the northern wall.

The cashel's interior is remarkably level, save for three low rock outcrops that break the otherwise smooth surface. This practical design would have made it ideal for housing both people and livestock within its protective walls. The site's elevated position offers commanding views across the surrounding countryside, a strategic advantage that would have been crucial for its original inhabitants, allowing them to spot approaching visitors or threats from a considerable distance.

Archaeological evidence suggests this type of ringfort, known locally as a cashel when built of stone rather than earth, would have served as a defended farmstead for a prosperous family during the early medieval period, roughly between the 5th and 12th centuries. Today, the structure sits peacefully in good quality pasture land, its weathered stones bearing silent witness to over a millennium of Donegal's history. The site was formally documented in the Archaeological Survey of County Donegal in 1983, ensuring its significance is preserved for future generations to study and appreciate.
