No wall, no ditch, no raised lip of earth remains to tell you something was once here. The only evidence is contradictory, and quietly puzzling: two maps, drawn decades apart, that cannot quite agree on what they were looking at.

When the Ordnance Survey produced its six-inch map in 1838, surveyors recorded a subrectangular enclosure on the hillock, measuring roughly 26 metres east-west and 18 metres north-south. Enclosures of this kind in the Irish landscape are often the remains of early medieval ringforts or farmsteads, defined by earthen banks or ditches that once marked out a domestic or agricultural space. When a second survey was carried out between 1912 and 1916 for the larger-scale OS 1:2500 plan, the same feature was recorded again, but this time as a roughly circular enclosure, around 18 metres in diameter. The shape had changed in the telling, or perhaps in the seeing. Whether the original form had already degraded between one survey and the next, or whether the two teams simply interpreted the same eroded feature differently, is impossible to say now. Either way, by the time anyone looked closely again, no visible surface trace survived at all.
