No earthworks, no stones, no visible boundary of any kind breaks the surface of the field. The enclosure exists, for most practical purposes, only as a photograph.

What gave it away was a single aerial survey carried out in 1972, recorded under the reference FSI 4513/4. The image captured a circular cropmark, roughly 30 metres in diameter, sitting on a natural rise in a field close to the townland boundary on a high ridge with long views across to Knockbrack. Cropmarks of this kind appear when buried archaeology affects how plants grow above it; the fill of a ditch or the compacted soil of an old bank can cause crops to ripen at slightly different rates, and from altitude those variations become legible as shapes. Circular enclosures of this general type are common across Ireland and often date to the early medieval period, serving as farmsteads, burial grounds, or places of assembly, though nothing in the available record pins a specific function or date to this one. What is known is its form, its approximate size, and the fact that it occupies an elevated position that would have commanded a wide outlook.

The site sits within a large field in Loughmain, positioned near the townland boundary, and the ridge setting is the clearest indicator of where to orient yourself if you visit the area. At ground level there is simply nothing to see, and the enclosure's outline would only resolve itself again from the air under the right crop conditions. The 1972 photograph remains the primary evidence. The record was compiled by Geraldine Stout and updated by Christine Baker, uploaded to the Sites and Monuments Record in October 2014.
