Measuring around thirty metres in diameter, the enclosure was duly entered as a site of potential archaeological significance in the early 1990s, listed under that broad and usefully vague category simply as "Enclosure." When someone finally went up to look at it properly in 1998, the wall proved to be a narrow drystone construction of apparently modern origin, with a handful of larger stones near the base that hinted at something older beneath, or perhaps just at the ordinary way fieldstone gets reused over generations.

Drystone walling, built without mortar by laying stones so that they lock and balance against one another, is a technique with deep roots in the west of Ireland, and a wall built this way in the twentieth century can look, at a glance, very much like one built in the Iron Age. The interior of this particular enclosure offered no further clues, being rocky and uneven with only a partial cover of grass, the kind of terrain that resists confident interpretation. The site does sit on ground with good views to the north and east, with Knockauns Mountain itself rising to the southwest, which is exactly the sort of exposed, commanding position that genuinely ancient enclosures often occupy. That coincidence was presumably enough, at some distance, to earn it a place on the map.
