A caher, or stone-walled ringfort, is the kind of structure that once marked out a farmstead in early medieval Ireland, its thick drystone walls enclosing a household and its activities. Here, however, a survey carried out in 1999 found no above-ground trace at all. The site had, by that point, been swallowed entirely by scrub and slope.

What makes the place quietly puzzling is how the cartographic record changed over the decades. The 1842 edition of the Ordnance Survey six-inch map recorded it as a rectangular enclosure, while the 1916 edition depicted the same feature as circular, with hachuring to suggest relief. Whether that shift reflects a genuine reinterpretation of the remains or simply different surveyors reading a badly degraded feature in different ways is not clear. The antiquarian Thomas Johnson Westropp, writing in 1901, mentioned three levelled cahers in the area alongside the nearby Cahermoyle, and this site is thought to be one of them. Westropp was a prolific recorder of Munster antiquities, often working in precisely the kind of terrain where official surveys missed things or got them wrong. That his cahers were already described as levelled at the turn of the twentieth century suggests the damage was well advanced long before anyone thought to inspect more carefully.
