In a field near Cloonee in County Galway, the first edition of the Ordnance Survey six-inch map records an oval enclosure, roughly 35 metres by 25 metres, sitting some 50 metres south of a neighbouring ringfort. No earthwork, no ditch, no raised ground remains to confirm it today. The site has, in the language of fieldwork, no visible surface trace.

A ringfort, to use the broadest description, is a circular or oval area enclosed by one or more banks of earth or stone, used primarily as a farmstead during the early medieval period in Ireland, roughly between the fifth and twelfth centuries. Thousands survive across the country in various states of preservation. This one does not. What the map recorded, and what the ground no longer shows, may have been levelled by centuries of agricultural clearance, ploughing, or simple erosion. The proximity to a second, surviving ringfort nearby suggests that this part of Cloonee was once a more densely settled early medieval landscape than the empty fields now suggest. Two enclosures in close proximity occasionally indicate family groupings or successive occupation of the same general area, though in this case the evidence is too thin to say much with confidence.
