A small circular enclosure once occupied this ground, set on a break in the hillside with views across the Blackwater River valley to the north and the Owenbaun River valley to the east. By the time anyone thought to look carefully, it had already largely vanished, reduced to a faint scarping of the earth on the downslope side, the kind of subtle earthwork that rewards patient looking but gives little away at first glance.

The 1842 Ordnance Survey six-inch map recorded the site as a hachured circular enclosure roughly fourteen metres in diameter, a modest ring by any measure. By the 1904 revision, surveyors were depicting it as a hachured platform of only about ten metres across, suggesting that the feature had already lost much of its definition over those intervening decades. A 1937 account by Broker noted it as lying on the land of a John Mahony, describing it simply as a fort of less than a quarter of an acre, very small. Enclosures of this type, sometimes called ring forts or raths, were typically used as enclosed farmsteads during the early medieval period in Ireland, their banks and ditches providing security for a household and its animals. This one was always on the smaller end of the scale. Adding a further layer of interest, a possible souterrain may lie within the interior. A souterrain is an underground stone-lined passage or chamber, often associated with early medieval settlement, and used variously for storage, refuge, or ventilation of a dwelling above. Whether that underground element survives intact beneath the pasture here remains uncertain.
