It is easy to walk past without registering what you are seeing, but the slight scarped edge, that is, the deliberate cutting or shaping of the ground to create a defined drop, marks this out as something made rather than merely natural. The enclosure at Coolreagh, in the old barony of Connello Upper, measures roughly 15.5 metres from north to south and 24 metres from east to west. The scarp itself is about 3.5 metres wide and just over half a metre high, which is modest enough to be dismissed as a trick of the terrain, yet consistent enough in its oval circuit to suggest clear human intent.

Enclosures of this kind are scattered across the Irish countryside and their purposes varied considerably. Some served as ringfort annexes or cattle pounds, others as early ecclesiastical precincts or simple settlement boundaries. Without excavation it is rarely possible to say which function any one example served, and the record compiled by Denis Power, uploaded to the National Monuments database in August 2011, makes no claim beyond the observable facts. What the record does note is that the interior slopes gently down toward the east and remains under pasture, while briars and bushes have taken partial hold along the scarped edge, softening its outline without entirely obscuring it.

A farm trackway skirts the scarp along its north-east to south-east arc, which means that anyone working the land here has been navigating around this feature for generations, probably without giving it much thought. That incidental preservation is worth something. Visitors approaching the area should expect ordinary working farmland; there is no formal access, no signage, and no interpretation on site, so the usual courtesies around land access apply. The feature is best observed in late autumn or winter, when lower vegetation makes the scarped edge easier to read against the surrounding ground. The thing to look for is the slight but consistent change in level that traces the oval perimeter, and the way the interior platform sits, almost imperceptibly, above the fields around it.
