This one in Castlegar, on the northern slope of a low east-west ridge in what was once demesne land, now asks visitors to read the ground itself. The enclosure, roughly thirty metres across, no longer has any visible structure to speak of. What remains is a slight rise at the north-west that may follow the line of a bank, and a shallow curving depression running from the east around through the south to the west-south-west that may trace the line of a fosse, the ditch that would originally have defined the enclosure's boundary. The interior is uneven underfoot, scarred by the removal of tree stumps.

The site was recorded as recently as the 1915 third edition of the Ordnance Survey six-inch map, where it appeared as a tree-covered circular enclosure, still intact and wooded. At some point after that, the surrounding woodland was cleared, and local information suggests the monument was levelled during that process. Circular enclosures of this kind are among the most common monuments in the Irish landscape; they served various purposes across different periods, from enclosed farmsteads to ceremonial sites, and their circular earthen banks and surrounding ditches were once a familiar feature of the countryside. This one, sitting within what had been the managed grounds of a landed estate, survived long enough to be mapped but not long enough to be preserved.

There is little to guide a visit in any practical sense. The landscape has been thoroughly altered, and what archaeologists describe is less a monument than a faint memory of one, legible only to a careful eye and some prior knowledge of what to look for.
