This is a rath, the Irish term for a ringfort, which was the standard form of rural settlement in early medieval Ireland, typically used by farming families between roughly the fifth and twelfth centuries. They were not military fortifications in any grand sense, but enclosed homesteads, the bank and ditch providing a degree of security for people, livestock, and stored goods.

The site measures approximately 38 metres across on its west-southwest to east-northeast axis, making it a fairly typical example in terms of scale. The earthen bank survives to an internal height of around 1.4 metres along the southern to northwestern arc, with a shallow external fosse, essentially a ditch dug to supply material for the bank, running about 3 metres wide along part of that same stretch. The northwestern to southern section of the bank has been levelled, though a low rise in the ground still traces its former line. What remains of the original bank has been absorbed into the local field boundary system over the generations, and deciduous trees have been planted along it, which is a common fate for these structures across the Irish countryside. The position on the lip of a steep northward fall to the river is characteristic of ringfort placement, which often favoured elevated or naturally defended ground with good views of the surrounding land.
