A bank and fosse, meaning a raised earthen boundary and accompanying ditch, would have defined the perimeter of a space roughly eighty metres across. Such enclosures are commonly associated with early medieval settlement, the circular ringfort being perhaps the most widespread monument type surviving across Ireland, built by farming families to protect livestock and mark out their territory. This one, however, no longer survives.

The third edition of the Ordnance Survey six-inch map, published in 1931, recorded the enclosure clearly: a curving line of hachures, the small marks used by cartographers to indicate an earthen bank or rising ground, traced the structure from the north-east round through south to south-west, where a curving field boundary, which also served as the townland and barony boundary, continued the arc northward. The enclosure was still legible on that map, but by the late 1970s it had been levelled. The landowner confirmed that the bank and fosse had been there before the ground was cleared. What was once a monument of some scale left behind only indistinct undulations in the field, and farm buildings now occupy the western and northern sectors of the site. A comparable enclosure of similar dimensions once stood approximately 325 metres to the north, suggesting this was not an isolated feature but part of a broader pattern of early occupation across this part of Galway.
