This is a rath, the more commonly used Irish term for a ringfort, a class of enclosed settlement built mostly between the seventh and tenth centuries and once numbering in the tens of thousands across Ireland. Most were farmsteads, their circular banks and ditches marking out a household's living space and livestock enclosure. Here, the circular area measures about 20.8 metres in diameter, modest even by the standards of the type.

What survives is slight but legible if you know what to look for. The earthen bank, roughly four metres wide, has been worn down to an external height of only half a metre and shows internally as little more than a faint lip along the ground. Outside it ran a fosse, the term for a defensive or drainage ditch, but this too has largely silted and flattened; it is now traceable only along the northern, upslope arc of the circuit, where a growth of rushes marks the line of slightly wetter ground it still creates. The interior slopes gently downward toward the south-west. Along the northern half of that interior, immediately inside the bank, there is a flat terrace about 6.4 metres wide and roughly half a metre high. The most likely explanation is that material from the bank was deliberately levelled here at some point, perhaps to create a working surface on the steeper side of the slope.

The site sits in working grazing land on a ridge, and the sloping approach from the south-west would have made the northern bank the most structurally significant part of the original enclosure. That is also where the most readable traces remain today, the slight hollow of the fosse and the rush growth above it offering a more reliable guide to the circuit than the eroded bank itself.
