The monument appears on historical Ordnance Survey maps as a circular enclosure measuring 50 metres across its interior, with an overall diameter of 76 metres when including its defensive features. A public road has bisected this ancient site since at least 1839, when it was first recorded on the inaugural OS 6-inch map, cutting through the monument from northwest to southeast much as it does today.

The site’s appearance changed notably between surveys; by the time cartographers returned for the 1899-1902 revision, they documented a rather different structure. Instead of the circular form, they recorded a sub-rectangular enclosure surrounded by a waterlogged fosse, or defensive ditch, measuring approximately 5 to 7 metres wide. This water-filled barrier would have provided both defence and drainage, typical features of medieval moated sites that often protected manor houses or agricultural settlements.

Archaeological surveys have revealed additional complexity to the area, with a rectangular enclosure visible as a cropmark situated about 60 metres to the northwest. This secondary feature, catalogued as KK024-151, suggests the site may have been part of a larger medieval complex or seen multiple phases of occupation. Today, while nature has reclaimed much of the monument, these earthworks remain as subtle reminders of medieval life in rural Kilkenny, their overgrown banks and waterlogged ditches preserving the footprint of a settlement that once stood at this crossroads.
