No walls, no earthwork to speak of, no local memory attached to the ground. The only reason anyone knows it is there at all is a cropmark, the faint differential in how crops grow over buried or disturbed soil, captured on an aerial photograph taken in July 2005. From the air, the roughly circular outline was legible enough to identify as an enclosure, the kind of defined, bounded space that appears throughout the Irish countryside in many forms, from prehistoric ringforts to early medieval farmsteads.

The story of how it almost disappeared entirely is layered into older maps. The second edition Ordnance Survey six-inch map, published in 1903, shows that part of the enclosure's bank had already been absorbed into the field boundary system of the time, with boundaries running along the south-east and south-west edges of the site. By the time anyone looked closely at the field again, the landowner confirmed that those boundaries had been removed at least thirty years prior, erasing even that secondary trace. There was, moreover, no tradition among local people of any monument or notable feature associated with the field, which is itself an unusual circumstance. Many archaeological sites in Ireland persist in folk memory long after the physical evidence is gone; here, the landscape kept no such record. What remains is a slightly raised area, just perceptible underfoot or at a low angle of light, though the dimensions of the original enclosure could not be reliably measured.
