That is, for now, very nearly all that can be said with certainty. It has been recorded, given a classification, and placed on the map of Irish archaeological monuments, yet the details that might explain it, its age, its shape, its purpose, the people who built or used it, remain officially undisclosed. The monument exists in a kind of administrative limbo, acknowledged but not yet described.

Enclosures are among the most common and most varied features in the Irish landscape. The term covers an enormous range of structures, from prehistoric ringforts, which were enclosed farmsteads typically defended by an earthen bank and ditch, to early medieval ecclesiastical enclosures that once defined the boundaries of monastic communities, to later field enclosures of uncertain purpose. Without further detail, Treannaskehy's example could belong to almost any of these traditions. Mayo itself is rich in such remains, its boglands and hillsides having preserved earthworks that elsewhere were ploughed away long ago. The townland name, with its Gaelic roots, hints at a settled landscape with a long memory, though what the enclosure itself remembers is, for the moment, unknown.
