What survives of this ringfort, or rath, is only a partial arc of earthen bank, standing about a metre high and curving from the south around to the east, its outer edge now absorbed into a modern field boundary. The full circle, roughly 35 metres across, has otherwise been levelled by centuries of agricultural work, yet the shape was clear enough to be recorded on Ordnance Survey maps in both 1842 and 1903, drawn with the hachured lines that cartographers used to indicate earthworks.

Ringforts were the standard farmstead enclosure of early medieval Ireland, typically dating from around the sixth to the twelfth century. A family would raise a circular bank of earth and, sometimes, a surrounding ditch, enclosing a domestic space where houses, animals, and stores were kept. What makes the Berrings example particularly interesting is the souterrain in its interior. A souterrain is an underground stone-built passage or chamber, constructed beneath the surface of the enclosure, and thought to have served as storage space, a refuge, or both. They are frequently associated with ringforts across Ireland, though their precise function in any given case is rarely certain. The presence of one here indicates that whoever occupied this enclosure invested considerable effort in its construction, even if the earthworks above ground have not fared so well against the plough.
