That gap, in its own way, says something. Enclosures of this kind, circular or sub-circular boundaries formed from earthen banks, stone walls, or a combination of both, are among the most common prehistoric and early medieval features in the Irish landscape. They served many purposes across many centuries: farmsteads, burial grounds, ceremonial spaces, places of assembly. Without further detail it is impossible to say which of these Cornaroya's enclosure represents, and that uncertainty gives it a particular quality, the quality of something not yet spoken for.

Cornaroya sits in a part of Mayo shaped as much by Atlantic weather and post-Famine silence as by anything that came before. Enclosures in this region tend to date from the Bronze Age through to the early medieval period, roughly spanning several thousand years of continuous, if fluctuating, human activity. Many were constructed as ringforts, known in Irish as ráth when earthen and caiseal or cashel when built in stone, and served as enclosed farmsteads for a single family and their livestock. Others predate this entirely. Without excavation, even a trained eye on the ground cannot always say with confidence what a particular enclosure was for or when it was made. The fact that this one has been formally recorded as a monument means it was considered significant enough to note, even if the detail behind that judgement remains, for now, out of reach.
