The cliff runs from west to north-east, and a drystone wall picks up where the rock leaves off, completing the enclosure around to the south. Together, they define a space of approximately thirty-five metres across in both directions. It is the kind of place that could pass unnoticed, particularly with a modern house immediately to the south, yet underneath the visible drystone construction, a stretch of earlier walling survives, around ten metres long and a metre and a half wide, suggesting that people were deliberately enclosing this spot long before the current stonework was laid.

The site appears in the Record of Monuments and Places, dated 1996, under the cautious designation "Enclosure Possible", which reflects the difficulty of classifying a structure where the natural landscape and human intervention are so thoroughly entwined. A cashel, the Irish term for a stone-walled ringfort typically associated with early medieval settlement, sits roughly seventy-three metres to the east-north-east, and a separate enclosure lies about eighty-eight metres to the north-east. The proximity of these features to one another, set within what is described as an extensive field system, points to a landscape that was once carefully organised and well used. Whether the Clooneen enclosure functioned as a settlement, a stock enclosure, or something else entirely is not resolved, and the "possible" classification keeps that question open.

The interior of the enclosure slopes downward from its centre toward the north and west, which gives the space an unusual, slightly bowl-like quality when approached from those directions. That topography, combined with the cliff edge and the remnant walling still legible beneath later stonework, makes this a place where several periods of use seem to have accumulated quietly on top of one another, without any single period declaring itself the definitive one.
