The possible enclosure at Lea Beg, in County Offaly, offers nothing of the sort. It exists, as far as anyone can tell, only in a single set of aerial photographs taken in 1973, and it leaves no impression whatsoever on the ground beneath your feet.

The site was identified from GSI aerial photographs, reference N 186/5, shot by the Geological Survey of Ireland in 1973. Aerial photography has long been one of archaeology's more quietly remarkable tools: crop marks, soil discolouration, and subtle variations in vegetation can betray the outlines of buried features, such as ditched enclosures, that are entirely invisible at ground level. What the 1973 photographs showed at Lea Beg was enough to suggest a possible enclosure of archaeological significance, though it never appeared on any edition of the Ordnance Survey six-inch maps, meaning it either escaped the attention of nineteenth-century surveyors or had already left so faint a trace that there was simply nothing to record. Whether the feature beneath the soil is a ringfort, a field boundary, or something older remains an open question.
