What makes it worth noting is precisely that absence. The first edition of the Ordnance Survey six-inch map, produced in the nineteenth century, recorded a circular enclosure here with a diameter of roughly twenty-five metres, but no surface trace of it survives today.

Circular enclosures of this kind are a common feature of the Irish landscape, often the remains of ringforts, which were enclosed farmsteads typically built during the early medieval period, between roughly the fifth and twelfth centuries. They range from simple earthen banks to more substantial stone-walled structures, and they once numbered in the tens of thousands across the country. The Eochaire example, modest in scale at twenty-five metres across, would have sat within that broad tradition. The undulating scrubland that surrounds the site today, lying to the south of the Knockbane River, has swallowed whatever earthworks once defined it. The OS mapping provides the only reliable record that anything was ever there at all.
