This is a rath, the Irish term for a ringfort, a type of enclosed farmstead typically dating from the early medieval period, roughly 500 to 1000 AD. The earthen bank that defines this one still stands to a height of around one and a half metres, and the shallow external ditch, or fosse, that once reinforced it remains faintly visible. A gap of just over two metres in the north-east sector is the likely position of the original entrance, oriented, as was common, away from the prevailing westerly winds.

The site was recorded as part of an archaeological survey of the Ballinrobe district compiled by D. Lavelle and published in 1994 by the Lough Mask and Lough Carra Tourist Development Association. At roughly 62 to 63 metres across, this is a reasonably substantial example of its type. What makes it particularly interesting is the presence of a mound in the western portion of the interior, measuring nearly fourteen metres in length, almost ten metres wide, and nearly two metres high, composed of both earth and stone. Such internal features are not universal in ringforts and may represent a raised platform associated with a dwelling, a later addition to the site, or something else entirely. The interpretation remains open.

The site has not escaped the pressures of working farmland. A modern track cuts straight through the interior from north to south, entering and leaving through gaps that have been broken in the bank at either end. A field fence bisects the eastern half of the interior along roughly the same axis. These intrusions are legible on the ground, which means a visitor can still read the original form of the enclosure while also seeing exactly how successive generations of land use have negotiated around, and through, an ancient boundary they could not entirely ignore.
