This enclosure in Brenormore, County Tipperary, does none of that. On the ground, it is effectively invisible, a stretch of gently undulating pasture on a slope that falls away to the north-west toward a stream valley, offering no wall, no ditch, no outline that the eye can follow. What pattern there is in the land makes no discernible sense to a person walking it.

The site exists on record because of a single aerial photograph, reference GSI S.502/1, taken in June 1973. From the air, the geometry that ground-level observation cannot resolve sometimes becomes legible, and it was through this photograph that the enclosure was first identified. Aerial survey has been responsible for locating a considerable number of Irish enclosures that left no upstanding trace, their outlines surviving only as cropmarks or soil discolourations visible under particular conditions of light, moisture, and vegetation growth. The Brenormore site sits in pasture that was, at the time of recording, recently grazed to the north-west and in lush growth to the south-east, a difference that may itself reflect underlying buried features. A related enclosure lies approximately 190 metres to the south-south-west, suggesting this part of Tipperary preserves traces of an organised, if now largely concealed, early landscape.
