That single word covers a great deal of Irish archaeological ground: enclosures can mean the remains of a ringfort, a cashel, a monastic boundary, or simply a defined space whose original purpose is no longer legible in the landscape. What draws attention to this particular one is less what is known about it than how little has been said, a site catalogued and passed on with the lightest of touches.

The townland name, Íochtar Cua, suggests a place long rooted in Irish-language geography, and south-west Kerry is a landscape dense with early medieval and prehistoric survivals. Enclosures of the kind found here were typically constructed during the early medieval period, roughly the fifth to twelfth centuries, and served as farmsteads, the circular or oval earthen banks defining a domestic space for a family and their animals. The published Archaeological Inventory of County Kerry, compiled by Ailbhe O'Sullivan and John Sheehan and issued in 1996, records this site among the many dozens of similar monuments catalogued across the region, each one a small node in a much larger pattern of early rural settlement.
