This modest earthwork is all that remains visible of a site that dates back to Ireland’s early Christian period. The mound sits atop a drumlin, one of those characteristic egg-shaped hills formed by glacial activity, offering commanding views across the surrounding countryside. At the base of this natural elevation, a holy well continues to mark the site’s religious significance.

The area is known locally as Racoo Children’s Burial Ground, a disused cemetery that occupies the same spot as the ancient religious foundation. Such repurposing of early ecclesiastical sites for later burial purposes was common throughout Ireland, particularly for unbaptised infants and children who, according to Catholic doctrine of earlier centuries, could not be buried in consecrated ground. These cillíní, as they’re known in Irish, represent a poignant chapter in the country’s social and religious history.

The site was documented in the Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, which catalogued field antiquities from the Mesolithic period through to the 17th century. Historical sources, including Gwynn and Hadcock’s work from 1970, confirm the location’s identity as Rath Cunga, whilst local tradition preserved by Ó Muirgheasa adds another layer to our understanding of this quietly significant place where early Christianity, medieval burial practices, and folk memory intersect.
