This is a cashel, the Irish term for a ringfort constructed from drystone walling rather than earthen banks, and it measures roughly 21 metres across. Unlike earthwork ringforts, which are more common across much of Ireland, cashels are typically found where good building stone is readily available, and the Galway landscape obliges on that count.

The enclosure is in fair condition, though the south-eastern arc of its wall has been partially obscured by field-clearance rubble, the kind of slow burial that happens when generations of farmers pile loose stone from their fields against whatever solid structure stands nearby. Inside, an old field wall cuts across the interior on a roughly east-west axis, dividing the space into two unequal sections. This later addition is almost certainly post-medieval in origin, a practical reuse of a ready-made enclosure long after anyone remembered, or perhaps cared, what it had originally been built for. Cashels like this one are generally associated with early medieval settlement in Ireland, broadly the period from the fifth to the twelfth century, and would have served as a farmstead enclosure, protecting a household and its livestock within the drystone perimeter.
