The feature is a circular earthen enclosure, roughly 35.5 metres across, defined by a low bank that has worn down considerably over time. These enclosures are a common enough class of monument in the Irish countryside, ranging in date from the prehistoric through to the early medieval period, though without excavation it is rarely possible to say which era produced any particular example. What gives this one a degree of quiet interest is a gap on its east-south-east side that may represent an original entrance, a detail that hints at deliberate design rather than gradual erosion.

The enclosure was noted by researchers Knight and Conway in the mid to late 1970s and subsequently recorded in the Archaeological Inventory of County Galway, compiled by Olive Alcock, Kathy de hÓra, and Paul Gosling and published in 1999. Beyond those bare references, the documentary record offers little. The site is described as poorly preserved, which is not unusual for earthworks of this kind; centuries of agricultural use, livestock grazing, and general weathering have a way of flattening banks that were once substantial enough to define a space clearly. The ridge setting, with its natural elevation and southward aspect, is a position favoured across many periods of Irish prehistory, offering both drainage and a degree of visibility across the surrounding terrain.
