The monument consists of a roughly D-shaped enclosure measuring about 25 metres north to south and 26.5 metres east to west. Its defining feature is a low earthen bank that varies in preservation; whilst parts remain intact at around 2.1 metres wide at the crest, the southern section has been reduced to little more than a scarp. A possible entrance can be spotted in the eastern quadrant, though centuries of weathering make this difficult to confirm with certainty.

What makes this site particularly intriguing is a crescent-shaped annexe that adjoins the southern side of the main enclosure. This secondary feature, measuring 6.5 metres by 21.2 metres, follows the natural contours of a spur along the ridge edge. Its bank, constructed from both earth and stone, stands more prominently than the main enclosure at up to 1.2 metres high on its external face, though it barely rises above ground level on the interior. The annexe appears to have been carefully positioned to take advantage of the natural topography, with the bank continuing to drop away following the natural slope.

Archaeologists note that whilst the enclosure’s shape and construction are similar to Irish ringforts, its elevated position is more characteristic of a ringwork castle, a type of Norman fortification common in the 12th and 13th centuries. This ambiguity in classification reflects the complex history of medieval fortifications in Ireland, where native Irish and Anglo-Norman building traditions often influenced one another. The site’s commanding position over the river valley would have provided both defensive advantages and control over movement through the landscape, making it a strategic location regardless of who built it.
