It is, in fact, a prehistoric or early medieval enclosure, the kind of enclosed circular space that appears throughout the Irish landscape and would once have defined a domestic or ritual boundary. What survives is a raised roughly circular area approximately nineteen metres in diameter, its edge marked by a low scarp, a stepped drop in the ground surface, running around the south-southeast to southwest arc.

On the northwest to southeast side, the enclosure's boundary has been absorbed into a later field boundary, which at six metres wide and nearly two metres in external height is a substantial structure in its own right. Drystone walling, a construction technique using carefully stacked stones without mortar, survives in sections along the inner face of this boundary, though much of it has collapsed over time into a broadly slumped heap of tumbled stone, heavily overgrown. The incorporation of earlier archaeological features into later field systems is common across Ireland, where successive generations found it practical to reuse existing earthworks rather than build anew, and in doing so inadvertently preserved fragments of them. Here, the older enclosure boundary and the later field wall have merged so thoroughly that the two are now difficult to read as separate things.
