This single-ringed feature, documented on the second edition of the Ordnance Survey 6-inch map as DG010-033001, offers a tangible connection to the area’s distant past. The wall’s careful curve suggests it was built to preserve or mark the boundaries of the original earthwork, though much of the site’s early structure has been lost to time.

What makes this location particularly poignant is its reported use as a children’s burial ground, or cillín in Irish tradition. These unconsecrated burial sites were typically reserved for unbaptised infants, stillborn babies, and young children who died before receiving the sacraments. Found throughout Ireland, cillíns often occupied liminal spaces; old ring forts, abandoned churches, or boundary areas between townlands. The practice, which continued well into the 20th century in some areas, reflects a complex intersection of Catholic doctrine and folk belief.

According to local historian M.R. Calhoun, the children’s burial ground is believed to be located at or very near this enclosure site. While no visible grave markers remain, such burial grounds rarely featured formal headstones, making them easy to overlook in the landscape. The site was formally recorded in the Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, ensuring its preservation in the historical record even as physical evidence continues to fade.
