This enclosure is a different kind of puzzle. Thirty metres across and defined by an earthen bank planted with trees and bushes, it has the appearance of something old and purposeful, yet its exact function remains genuinely uncertain.

The bank itself is modest, standing about a metre high on the outside and slightly less on the inside, with a width of roughly 1.6 metres. On the north-western side, faint traces of an external fosse, a shallow ditch that would originally have run around the outside of the bank, are still just visible. A gap on the east-north-east side looks like a later, probably modern, intrusion rather than an original entrance. The surveyors who examined it considered the possibility that it might be a tree-ring enclosure, a type of feature sometimes created to protect or commemorate a significant tree, often associated with the boundary planting of estate landscapes. But the siting on a rise and the proportions of the bank align closely with a rath, the ringfort-style enclosures that are among the most common early medieval monument types across Ireland and are particularly well represented in this part of Galway. The interior, which rises slightly towards the centre, was densely overgrown with thistles at the time of inspection, which tells its own quiet story about how thoroughly such features can withdraw from attention even when they remain physically intact.
