The site is a rath, the Irish term for a ringfort, which was the standard form of enclosed farmstead used across Ireland from the early medieval period onward. Most were built between roughly 500 and 1000 AD, though some are older, and they functioned as family homesteads, their enclosing banks offering a degree of protection for livestock rather than any serious military defence. This particular example measures around 42 metres across, making it a fairly typical specimen in terms of scale, and it retains both an earthen bank and a fosse, the shallow external ditch that would originally have reinforced the enclosure on the southern side.

The bank survives to only about 0.3 metres in height, and the fosse to a similar depth, which means centuries of cultivation and natural erosion have worn both features down considerably from whatever their original dimensions were. The surrounding field has continued to be worked, which goes some way to explaining the condition of the site. More visibly intrusive is a stone field fence that cuts directly through the north-western sector of the enclosure, a fairly common fate for earthworks that have long since lost any obvious function in the eyes of those farming around them. A survey of the Ballinrobe district compiled by D. Lavelle in 1994, covering the area around Lough Mask and Lough Carra, recorded the site as heavily overgrown at that time, a description that likely still holds.
