Yet deliberate it was. The enclosure measures approximately 28.5 metres north to south and 23 metres east to west, and where the bank survives best, on the western side, it still stands to a height of nearly two metres. Stone facing is visible along the north-northwest to north arc, and faint traces of an external fosse, a defensive ditch, survive around the perimeter.

This is a ringfort, or at least the remains of one, a class of enclosed settlement that was constructed and used across Ireland primarily during the early medieval period, roughly between the fifth and twelfth centuries. Ringforts ranged from simple earthen enclosures protecting a farmstead to more elaborate sites with multiple banks and ditches. This example at Dromore sits in classic ringfort territory: County Monaghan's drumlin landscape, with its long, whale-backed ridges of glacially deposited material, offered naturally elevated positions that made enclosures easier to defend and drain. The choice of the northern end of a ridge here is consistent with that practical logic. One detail that remains unresolved is the location of the original entrance, which has not been identified, suggesting the bank has degraded enough to obscure whatever gap or causeway once existed.
