In the rough grazing land of Canvarstown in County Kilkenny, an enclosure was recorded on the Grand Jury Map sometime between 1812 and 1824, tucked into a curious geographical fold where a river running east to west meets a north-south stream, and the townland boundary bends briefly to follow the junction before continuing north. The enclosure sat within that kink, a natural and administrative quirk of the landscape that made it, at least on paper, easy to locate. By the time anyone went looking for it on the ground, it had effectively ceased to exist.

The Ordnance Survey's first edition six-inch map of 1839 makes no mention of an enclosure here, nor does the revision carried out around 1900. What those later maps do show is a limekiln just south of the east-west river at the same location. A limekiln was a small stone structure used to burn limestone and produce quicklime, widely used in agriculture for improving acidic soils and in building mortar. Its presence suggests the area was being actively worked in the nineteenth century, and the quarrying that accompanied that activity may well account for the enclosure's disappearance. When the site was inspected in 1987, there was no trace of any enclosure at ground level, and the land around the limekiln had been quarried away. Whatever the original structure was, and whether it dated to early medieval, post-medieval, or some other period, the record from the early nineteenth century is now the only evidence that it stood there at all.
