At Knockanaddoge in County Kilkenny, a circular enclosure roughly 24 metres in diameter was recorded on the first edition Ordnance Survey six-inch map of 1839, plotted on the northern bank of a stream that feeds southward into the Dinin river. By the time the revised edition was produced in 1899, it had been left off entirely. Today, the ground shows nothing; the enclosure sits beneath grass, invisible at surface level, its outline absorbed into land that has since been reclaimed and stripped of the old field boundaries that once marked it.

Circular enclosures of this kind are a familiar feature of the Irish countryside, most often the remains of a ringfort, a type of enclosed farmstead used from the early medieval period onward, typically defined by an earthen bank or fosse. Whether this particular example at Knockanaddoge was of that type is not recorded. What the 1839 map does confirm is that it was legible enough to a surveyor working that year to be worth noting, a circle of modest size sitting above a minor watercourse with open views across the Dinin river valley. The sixty years between that survey and the 1899 revision were enough for agricultural improvement to erase whatever trace remained above ground, and with the removal of the surrounding field boundaries, even the landscape context that might have framed it has gone.
