Enclosures of this kind are among the most common yet least understood monuments in the Irish countryside. The term covers a broad range of features, from the circular earthen banks of early medieval ringforts, which served as farmsteads and status markers, to later field boundaries and ecclesiastical enclosures. Without more detailed survey information, the precise form and function of this particular site remains, for now, an open question.

Aghtaboy is a small rural townland, and like much of Mayo, the ground beneath and around it has been shaped by centuries of farming, clearance, and seasonal habitation stretching back into prehistory. Mayo's landscape holds an unusually dense concentration of ancient field systems, some of them famously preserved beneath the bog at Céide Fields to the north, which date to the Neolithic period. An enclosure in this county could belong to almost any era, its origins ranging from the Bronze Age to the early modern period, and its purpose from domestic to ritual to agricultural.
