That is, officially, almost all that can be said about it. It has been recorded, classified, and assigned a place in the national inventory of monuments, yet the details that would bring it to life, its shape, its age, the material from which it was built, remain catalogued but not yet publicly described.

Enclosures of this kind turn up across Ireland in considerable variety. Some are the earthen ringforts, known as raths or liosanna, that served as the defended farmsteads of early medieval families, their low circular banks now softened by centuries of grass. Others are earlier still, prehistoric in origin, or later, associated with ecclesiastical settlements or land management in the post-medieval period. Without more specific information about Leagh, it is not possible to say which tradition this particular site belongs to, or what condition it survives in today. What is certain is that the townland of Leagh sits within a county whose landscape is exceptionally dense with such remains, from the karst limestone expanses of the Burren's fringes to the quieter drumlin and bog country further east.

The enclosure at Leagh is, for now, a placeholder in the archaeological record, a name on a map pointing to something that was once deliberately made by people who had reasons for making it. That gap between the fact of its existence and any account of its meaning is itself a fair summary of how much of Irish prehistory and early history still stands waiting.
