Most raths, the roughly circular enclosed settlements built across Ireland during the early medieval period, have a single bank and ditch. This one was built with two concentric stone-faced earthen banks and a fosse, the ditch between them, arranged around an oval interior measuring 56 metres east to west and 45 metres north to south. That extra ring of earthwork suggests the enclosure's occupants either wanted, or needed, a more substantial barrier between themselves and the outside world, whether for livestock, status, or defence.

The rath sits on a broad north-south ridge in County Clare, roughly 300 metres west of the Rathborney River, set within what appears to be a much larger, multiperiod field system that predates and postdates the ringfort itself. The inner bank still carries remnants of its original stone facing on both interior and exterior sides, and at the north it is possible to estimate the facing gave a wall width of around 1.45 metres. The outer bank has fared less well; from the south-west round to the north it has slumped into the fosse, so the ditch is only readable as a genuine earthwork feature from the north to south-west. Viewed in aerial or satellite imagery, however, the full circuit comes through clearly. A gap in both banks at the east-south-east is likely where the original entrance once stood. In the level grassed interior, slightly to the south-east of centre, there is a possible hut-site, the kind of shallow depression or low platform that once supported a timber or wattle structure where people actually lived.
