No earthwork, no ridge, no shadow in the grass. The only reason anyone suspects it is there at all is a photograph taken from the air.

The site was identified as a possible enclosure through the Bruff 35 aerial photograph survey, which captured crop or soil marks invisible at ground level. Enclosures of this kind are among the most common archaeological features in the Irish landscape; they typically took the form of a circular or subcircular bank and ditch surrounding a domestic or ritual space, and can date from the Bronze Age through to the early medieval period. Over centuries, ploughing, grazing, and general land use can reduce such features entirely, leaving only faint traces detectable when soil disturbed by buried ditches retains or loses moisture at a different rate to the surrounding ground, creating patterns legible only from above. In this case, even the aerial evidence amounts to no more than a possibility.
