A circular enclosure roughly twenty metres across, it was recorded on the first edition of the Ordnance Survey six-inch map, which means that when nineteenth-century surveyors passed through this part of north Galway, something was still visible enough to commit to ink. Today, that something has all but vanished. A barely perceptible rise in the field surface and a slight curve in a boundary to the west are all that remain of what was once a defined, enclosed space.

Enclosures of this kind are among the most common, and most quietly erased, features of the Irish archaeological landscape. Circular enclosures typically served as the boundary of a ringfort or ráth, a type of defended farmstead used throughout the early medieval period, though some examples are earlier or later. The townland boundary, which cuts across this one at both its northern and southern edges, suggests the enclosure predates the administrative division of land into townlands, a process largely completed by the medieval period. A second enclosure was recorded approximately fifty metres to the north-east, hinting that this was not an isolated feature but part of a wider pattern of early settlement in the area. The proximity of St Mary's Church adds another layer; early ecclesiastical sites in Ireland frequently developed near, or directly over, pre-existing secular enclosures.
