Set among undulating pastureland in County Galway, this large oval enclosure carries a children's burial ground in its western half, a detail that quietly reframes the whole site. In Irish tradition, such burial grounds, known as cillíní, were used for unbaptised infants and others who could not be interred in consecrated ground. Their presence within or beside an enclosure of this scale is a strong pointer toward early ecclesiastical origins rather than the military or territorial function the word "fort" implies.

The enclosure itself is substantial, measuring roughly 98 metres north to south and 85 metres east to west, making it considerably larger than a typical ringfort. It surrounds a low hummock whose interior rises toward the centre, and its boundary is formed in two distinct ways: an earthen bank running from south to southwest, and a scarp, essentially a steep natural or cut slope, that defines the perimeter elsewhere. That scarp has been partially worn down along the eastern to southern arc, where walnut trees have been planted. A gap on the northern side, about five metres wide, may represent an original entrance. A narrow drain cuts across the interior from east-southeast to south, and the whole enclosure is ringed by mature trees, giving it an enclosed, self-contained quality even from a distance. The combination of the large diameter, the internal topography, and the burial ground has led archaeologists to suggest this may have begun life as an early ecclesiastical enclosure, perhaps the boundary of a small monastic or church settlement, later remembered only by its association with the dead.
