The monument itself consists of a low earthen mound, roughly oval in shape and measuring about 8 metres north to south and 5 metres east to west. Rising just half a metre above the surrounding landscape, it occupies the crest of an east-west ridge with commanding views across the countryside in both directions.

The most intriguing feature sits atop the northern half of the mound; a U-shaped arrangement of stones, open to the north and spanning 4 metres by 2.5 metres. Adjacent to this stone setting, touching its southeastern edge, lies a substantial subcircular slab measuring 2 metres by 1.7 metres and about 12 centimetres thick. The upper surface of this stone bears multiple cupmarks, each roughly 10 centimetres in diameter, adding an element of prehistoric mystery to the site. Victorian antiquarian Kinahan, writing in 1889, speculated that this cupmarked stone might once have served as a cover for the U-shaped structure, though this remains unproven.

While tradition firmly associates this spot with Columcille’s nativity, historians note that Churchtown, another site in the area, also claims this distinction. A modern cross has been erected nearby, testament to the enduring spiritual significance of the place. The archaeological record, compiled during the comprehensive Survey of County Donegal in 1983, preserves these details whilst acknowledging the competing claims and uncertain history that characterise so many of Ireland’s ancient monuments.
