This subcircular structure, built from carefully placed stones, measures just under 11 metres across its interior, with walls that vary between 1.25 and 1.5 metres thick. Though time has worn them down to about half a metre in height, the walls remain largely intact, cleverly incorporating natural rock outcrops into their construction. A gap of nearly two metres on the southeastern side provides the only break in this otherwise continuous barrier.

At the heart of the enclosure stands a cairn, a deliberately constructed mound of stones rising 1.2 metres high and spanning almost four metres in diameter. This central feature suggests the site held significant importance, possibly serving as a burial monument or ceremonial focal point for the local community. The careful placement at the centre of the walled space indicates deliberate planning and considerable effort went into its construction.

What makes this site particularly intriguing is the stone slab placed atop the central cairn. Measuring 90 by 46 centimetres, this slab has been shaped to create a rough cross profile when viewed from the side, varying in thickness from 9 to 17 centimetres. Its western face bears a simple inscribed cross, marking this as a Christian site or at least one that was adopted for Christian use. This combination of features; the circular enclosure, central cairn, and Christian symbolism; suggests a complex history where ancient traditions may have been adapted or repurposed as new beliefs took hold in the landscape of County Donegal.
