The uncertainty is the point. What survives is not the monument itself but only a name, recorded in the Ordnance Survey Name Books as 'Liscoolcraheen', a placename that quietly encodes the memory of something that no longer exists above ground. The first element, 'Lis', is a common Irish word for a ringfort or enclosure, and its presence in the local name was enough to suggest that a structure of that type once occupied this ground.

Placenames of this kind often outlast the physical remains by centuries. The earthworks of a rath, as these enclosures are also called, could be levelled by centuries of ploughing, drainage works, or simple agricultural improvement, yet the name would persist in oral tradition and eventually find its way into official records. In this case, no visible trace of any structure survives, and the site's identification as a ringfort rests entirely on that linguistic clue. It is a reminder that the archaeological record of rural Ireland is partly a record of absences, places where something once stood that can now only be inferred.
