This is a cashel, a type of ringfort built from stone rather than earthen banks, and what remains here sits quietly in rough pasture on a naturally raised area, its walls reduced by time and agricultural pressure to little more than a low scatter of stone, nowhere more than sixty centimetres high.

The enclosure is oval, measuring roughly 44 metres north to south and 51 metres east to west, and its surrounding wall, once perhaps two metres thick, has been largely levelled along its north-eastern to south-eastern arc. A field fence has been built directly over the wall on the southern side, the practical needs of farming having long since overwritten the archaeology beneath. The interior is overgrown and uneven, with evidence of clearance, the kind of surface disturbance that suggests stones have been removed and redistributed over the centuries. Most intriguing is a souterrain in the south-western part of the interior. Souterrains are underground stone-lined passages or chambers, typically associated with early medieval settlement in Ireland, probably used for storage and possibly as places of refuge. Their presence within a cashel is relatively common, but each one is a small puzzle of purpose and construction. This site was recorded by D. Lavelle in an archaeological survey of the Ballinrobe district, published in 1994, which catalogued monuments around Lough Mask and Lough Carra, two lakes that dominate this corner of Mayo.
