This one is different. A circular enclosure near Nohoval Church and Graveyard in Ballyegan, County Kerry, was identified not by anyone on the ground, but from the air, and even then only tentatively. At ground level, there is apparently nothing to see at all.

In early July 1987, a researcher named O'Hare was conducting an aerial survey when something in the landscape below caught attention: the faint crop or soil marks suggestive of a circular enclosure, sitting within the interior of a larger enclosure already associated with an early church site. The location places it immediately to the south-west of Nohoval Church and Graveyard, itself part of a cluster of related ecclesiastical features. Aerial photography is one of the principal tools for finding buried or vanished structures of this kind, since variations in soil moisture, crop growth, or ground disturbance can reveal the outlines of ditches and banks long since levelled. What O'Hare recorded in 1987 falls into this category of ghostly evidence, a possible inner enclosure within a possible church enclosure, nested features that might, if confirmed, point to a more complex and layered early medieval site than the standing remains alone would suggest. The word "possible" appears twice in the original observation, and that honest uncertainty is itself worth noting. The feature has no confirmed status, no excavated context, and no visible presence.
