In the townland of Dungarvan in County Kilkenny, a circular enclosure roughly fifteen metres in diameter was identified not by fieldwork or excavation but through a high-altitude aerial photograph taken between 1973 and 1977 by the Geological Survey of Ireland. The site had by then been reclaimed from scrubland, meaning that whatever surface trace once existed had largely been absorbed back into the working landscape. Its outline endured only as a crop or soil mark, legible from above at the right angle and season.

Enclosures of this kind are among the most common archaeological forms in Ireland, typically associated with early medieval settlement, though without excavation or dating evidence it is impossible to say more about this particular example. What adds quiet interest is that the same aerial photograph hints at a second, smaller enclosure approximately twelve metres to the north-west. The image of that companion feature is less distinct, leaving open the question of whether it represents a related structure or simply a trick of the light and soil. The two together suggest the possibility of a small cluster of activity at this spot, though that possibility remains exactly that.
