It measures approximately thirty metres in diameter, it sits on a flat terrace with open views to the north, east, and west, and the only evidence that it was ever there at all comes from a map drawn in 1839.

The first edition Ordnance Survey six-inch map, produced in that year, clearly marks a roughly circular enclosure at this location in Ballyroe. Enclosures of this kind are typically ringforts, the most common field monument in Ireland, built as enclosed farmsteads during the early medieval period and defined by a circular bank and ditch. By the time the Ordnance Survey revised its maps around 1900, the enclosure had disappeared from the record entirely. A field boundary running east-south-east to west-north-west was shown nearby, but the monument itself was gone, levelled at some point during the intervening sixty years as agricultural improvement reshaped the land. A second enclosure, also now levelled, once stood roughly 150 metres to the south-west, suggesting this part of the valley was once a more structured landscape than the open grassland that covers it today.
