It is a rath, the Irish term for a ringfort, the most common monument type in the Irish countryside. These were the enclosed farmsteads of early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries, built to define a household's space, provide a degree of security for livestock, and signal a family's standing in the landscape.

This particular example is univallate, meaning it has a single enclosing bank rather than the double or triple rings found at higher-status sites. The interior forms a roughly circular area measuring about 24 metres north to south and 28 metres east to west, enclosed by a bank nearly four metres wide. From the inside, the bank rises only about half a metre, but its outer face stands closer to a metre above the surrounding ground, giving it a more pronounced profile when viewed from outside. A fosse, the shallow ditch dug to provide material for the bank, survives at a depth of around 20 centimetres, though it is now only clearly visible in the south-east quadrant. The entrance, just under two metres wide, opens in the same south-east sector, a common orientation for ringfort entrances in Ireland. One further detail distinguishes the site: a field boundary wall curves around it concentrically from the west to the north-west, suggesting that at some point a later landowner incorporated the ancient monument into the organisation of the working farm, perhaps without fully recognising, or perhaps simply not caring, what it was.
