This circular stone structure, measuring nearly 11 metres across internally, features walls built from local stone that still stand over half a metre high despite centuries of weathering. The builders cleverly incorporated natural rock outcroppings into the wall construction, which varies between 1.25 and 1.5 metres in thickness; a deliberate gap on the southeast side likely served as the original entrance.

At the heart of this ancient enclosure stands a cairn, a carefully constructed stone mound roughly 3.9 metres in diameter and rising 1.2 metres from the ground. This central feature suggests the site held particular religious or ceremonial significance for the community that built it. The cairn’s purpose becomes clearer when examining what rests atop it: a stone slab bearing the unmistakable marks of Christian devotion.

The slab itself is a fascinating artifact, shaped to create a cross-like silhouette when viewed from certain angles, measuring 90 centimetres by 46 centimetres and varying in thickness from 9 to 17 centimetres. On its western face, someone carefully carved a simple cross, marking this place as sacred ground. Such ecclesiastical enclosures, known locally as ‘Bíofán’, were common features of early Irish Christianity, serving as boundaries for monastic settlements or marking places of worship and burial. This particular example, documented in the Archaeological Survey of County Donegal, represents the kind of modest yet enduring religious sites that dot the Irish countryside, each one a testament to the faith and craftsmanship of medieval communities.
