This one, in low-lying rough pasture near Rathpatrick in County Kilkenny, cannot be seen at all from the ground. A field inspection in 1987 found nothing visible at eye level, and the terrain, wet and uneven, offers no obvious clue that anything lies beneath. It is only from the air that the site reveals itself, as a ploughed-out bivallate ringfort roughly 100 metres in diameter. Bivallate means it once had two concentric earthen banks and ditches enclosing a central area, a more substantial arrangement than the single-banked ringforts that are common across Ireland, and one generally associated with higher-status settlement during the early medieval period.

The site was identified from a high-altitude Geological Survey aerial photograph, where indistinct earthen features were just legible against the surrounding pasture. It was recorded in the Record of Monuments and Places in 1996, listed simply as "Earthworks", a designation that captures how little survives at ground level. By 2013 it had become readable through satellite imagery, the pale cropmark geometry of the two rings tracing out what centuries of cultivation had long since levelled. A second bivallate ringfort of similar size sits around 400 metres to the north-east, suggesting that this corner of Kilkenny was once a more populated and organised landscape than its present quiet fields imply.
