4 metres high, measuring roughly five metres by six. A fort within a fort, its purpose unrecorded, its age unspecified, its function left entirely to speculation.

A cashel is a ringfort built from stone rather than earthen banks, a type of enclosed farmstead that was widespread across early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. This one at Kilbehy, in County Limerick, sits on a gentle east-facing slope amid outcropping limestone, a landscape that would have supplied building material close to hand. The main enclosure is sub-circular, spanning around 27.5 metres north to south and 30 metres east to west, enclosed by a stone bank that still stands about a metre high on the interior face and 0.8 metres on the exterior. According to the survey compiled by Denis Power and uploaded in August 2011, the bank is best preserved along its western side, while the north-eastern arc has eroded to little more than a low scarp. At the south-south-east, boulders have been dumped along the outer face, and shortly afterwards the bank is swallowed into the existing field boundary system at the south-west, as happens frequently when old structures become convenient walls for later farmers.

The interior is now covered by mature deciduous trees, which means the site reads more as a small woodland than an ancient enclosure when approached across the surrounding pasture. The western half of the interior sits slightly higher than the eastern, a subtle topographic detail worth noting when trying to read the space. The inner oval enclosure in the north-western quadrant is low and easy to miss beneath the tree cover, so it rewards careful looking. Access is across farmland, and as with most such sites in private ownership, it is worth approaching respectfully and being aware that the field boundaries in the immediate area have incorporated parts of the original structure, making the south-western perimeter harder to trace.
