There is nothing to see from the ground, no earthwork, no raised bank, no hollow in the grass. The only evidence that anything is there at all came from the air, in 1971, when an aerial photograph captured a cropmark tracing the outline of the enclosure below.

Cropmarks form when buried features alter how plants grow above them. Stone walls or compacted ditches stress crops in dry conditions, while pits and ditches filled with looser, moisture-retaining soil encourage more vigorous growth. From the air, these subtle differences in colour and height resolve into shapes, circles and rectangles and lines, that correspond to structures long since swallowed by the earth. The Connahy enclosure appears as one such circle, its diameter suggesting a modest enclosed space of the kind associated across Ireland with early settlement, agriculture, or ritual activity, though nothing in what is known about this particular site specifies its age or purpose. What the site does have, notably, is position: the valley floor offers clear sightlines in every direction, which may or may not have mattered to whoever established the enclosure, and may simply be a feature of the landscape rather than a deliberate choice.
