Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically enclosing a farmstead within one or more circular earthen banks. What makes this example worth pausing over is its bivariate construction: two concentric banks separated by a fosse, the term for the ditch dug between them, giving the enclosure an added layer of definition that hints at a household of some local standing.

The site measures roughly 39 metres north to south and 37 metres east to west, making it a fairly substantial example of the type. The inner bank still stands to a height of 1.6 metres, and the outer to around 1.2 metres, with the intervening fosse dropping to a depth of approximately 0.8 metres. These earthworks survive best along the north-east to east arc and from the south-east round to the west, though the interior and the northern bank have suffered from quarrying at some point in the past, likely for stone or useful fill. A possible entrance gap on the eastern side, around 2.9 metres wide, aligns with a common convention in Irish ringfort construction, where eastward-facing entrances were favoured. Marshy ground to the west of the knoll may well have influenced the original choice of this slightly elevated position, offering a degree of natural drainage and visibility that flatter ground nearby could not provide. The site was recorded in a 1994 archaeological survey of the Ballinrobe district compiled by D. Lavelle, covering the wider area around Lough Mask and Lough Carra.
