The enclosure measures roughly 39 metres north to south and 41 metres east to west, making it a substantial example of a rath, the Irish term for a ringfort, which was the standard form of rural settlement in early medieval Ireland. Farmers and their families lived inside these circular enclosures, protected by the bank and an external ditch, and tens of thousands of them once dotted the Irish countryside. Most have been ploughed flat or built over; this one survives with its earthen bank still standing 1.2 metres high and its outer fosse, a defensive ditch, still visible at around half a metre deep.

The entrance faces east, as was common with ringforts, and a causeway crosses the fosse to reach it, the gap measuring 2.2 metres wide. That eastward orientation is thought to reflect both practical and symbolic concerns, catching the morning light and facing away from the prevailing Atlantic weather. The interior is now tree-lined, which gives the site a quietly enclosed character that open pasture alone would not produce. The site sits in the district covered by a 1994 archaeological survey of the Ballinrobe area, including the landscapes around Lough Mask and Lough Carra, compiled by D. Lavelle, which recorded the structure as part of a broader effort to document the archaeology of that lake-rich corner of Mayo.
