Roughly circular, measuring about 24 metres north to south and just over 20 metres east to west, it is the kind of feature that reads as a slight thickening of the ground rather than a structure, until you notice that the interior dips gently downward toward the east and that there is a deliberate gap in the bank to the south-south-east, a 4-metre-wide entrance that has held its shape for centuries.

This is an earthen enclosure, a category of monument found across Ireland that encompasses everything from ringforts used as defended farmsteads in the early medieval period to stock enclosures of uncertain date. The bank here is modest, rising to a maximum of half a metre on the interior face and only about 15 centimetres on the exterior, which suggests a boundary that was more about definition than serious defence. Ringforts, sometimes called raths, typically served as the enclosed farmsteads of relatively prosperous families between roughly the fifth and twelfth centuries, though many earthen enclosures are difficult to date precisely without excavation. The southeast-facing entrance is a common orientation in Irish examples, thought by some researchers to reflect practical considerations of shelter and morning light.
