It has been levelled completely, leaving no visible surface trace, and yet it remains on record as a place of genuine archaeological significance, a circular enclosure roughly thirty metres in diameter that once stood as a typical example of early medieval rural settlement in Ireland.

Ringforts, known in Irish as raths, were the most common form of farmstead in early medieval Ireland, usually consisting of a circular area enclosed by one or more earthen banks and ditches. They served as farmsteads and places of shelter rather than military fortifications in most cases. The one at Rathcobane was documented on Ordnance Survey six-inch maps in both 1904 and 1936, appearing as a clear circular enclosure on both editions. At some point between those surveys and the present, the earthworks were removed, most likely through agricultural clearance. What makes this particular site quietly notable is that it is not alone in its fate: a second levelled circular enclosure of the same type lies approximately 140 metres to the southwest, suggesting that this slope once held a small cluster of early settlement activity, both examples now erased from the landscape but preserved only in maps and records.
