Roughly 36 metres in diameter, it survives only as a low bank of earth, worn down to the point where it reads more as a gentle rise in the ground than a deliberate structure. A field boundary, drawn at some later point, cuts directly through its northern arc, a small act of agricultural practicality that has blurred whatever shape the enclosure once held.

Circular earthen enclosures of this kind are fairly common across the Irish countryside, typically interpreted as the remains of early medieval ringforts, though some examples are considerably older. A ringfort, or rath, would originally have enclosed a farmstead, its earthen bank offering a degree of protection for people, livestock, and stores. The Cloonteen example sits within an older field system, which hints at a landscape that has been worked and reorganised across many centuries, each generation leaving its own marks on top of earlier ones. The enclosure itself is now very poorly preserved, the bank so reduced that it takes some deliberate attention to trace its arc through the grass.
