What makes it worth pausing over is its double boundary: two earthen banks with a fosse between them. A fosse is simply a defensive ditch, typically dug to reinforce an earthwork, and here one survives to a depth of around 0.9 metres, though the outer bank and fosse have been levelled across the eastern to south-western arc, worn down to roughly 0.3 metres. The inner bank, standing at 0.9 metres, has accumulated considerable vegetation and shows signs of erosion, giving it that half-absorbed-by-the-landscape quality common to earthworks that have been neither maintained nor actively destroyed.

The enclosure is not alone in this landscape. Two ringforts, the enclosed farmsteads of early medieval Ireland typically consisting of a circular area bounded by one or more earthen or stone banks, lie within 250 metres of this site, one roughly 200 metres to the north-west, another about 250 metres to the south. Whether this enclosure belongs to the same broad period of settlement activity or represents something functionally different is not recorded, but the clustering of enclosed sites in the area points to a stretch of countryside that was clearly organised and inhabited over a long period. The description comes from D. Lavelle's 1994 archaeological survey of the Ballinrobe district, which covered the wider territory around Lough Mask and Lough Carra.
