The structure is D-shaped, a form commonly associated with early Irish settlement or ceremonial use, and its dimensions are substantial: roughly 93 metres along its longer axis and 46 metres across. The straight edge of the D runs parallel to the lip of the ridge on which it sits, suggesting its builders were working deliberately with the natural topography rather than simply clearing a convenient flat space.

The enclosure sits on a ridge overlooking the River Nore, which runs approximately 100 metres to the east. That relationship between elevated ground and a river is a recurring pattern in early Irish landscape use; the combination offered defence, visibility, and access to water in roughly equal measure. The northern portion of the monument has been built over by a large agricultural shed, aligned along the same north-east to south-west axis, while the southern portion lies under a concrete yard and car park. The result is that a monument of considerable scale has been effectively absorbed into an everyday working landscape, visible now only as an outline on aerial surveys or in the slight irregularities of the ground where the enclosure bank has not been entirely levelled.
