It was only when someone walked the ground in 1997 that the reality became clear: a rectangular enclosure roughly fifteen metres by eighteen, its boundary formed by a low spread of stone with a drystone wall along the top, rising to about a metre at its northern side. Drystone construction, which uses no mortar and relies entirely on the careful placement of stone, is common across the Irish landscape, but walls that survive at even half a metre tend to attract attention. This one had been quietly sitting in a field system that spreads across several townlands, largely unremarked.

The enclosure sits on a gentle south-facing slope, and a slight field wall runs east to west across its northern interior, suggesting the space was subdivided or later interfered with. What makes the location particularly interesting is its immediate neighbourhood. A cashel, which is a stone-walled ringfort typically associated with early medieval farming settlement, sits fifty metres to the north-west, and a second cashel lies fifty metres to the south-east. The enclosure is effectively bracketed by them. Whether it was contemporary with either, or belongs to a different phase of activity within the same extensive field system, is not established. The aerial photograph that first flagged it, taken under conditions that made the subrectangular outline visible, gave no indication of how much lay beneath the grass.
