The wall, running north to south, is almost certainly responsible for one of the gaps now visible in the earthen bank, the original builders having had nothing to do with it. A second gap to the north-east was probably knocked through at some later point to allow livestock to pass, a small practical intrusion that has left its mark on the archaeology.

Ringforts, known in Irish as raths, were enclosed farmsteads typically built during the early medieval period, roughly between the fifth and twelfth centuries. They functioned as defended homesteads for farming families, the enclosing bank and, where present, an outer ditch providing protection for people and animals alike. This example at Leamaneh sits on a level shelf at the base of a south-east facing slope, with higher ground rising about a hundred metres to the north and a valley opening out to the east. The enclosure is roughly circular, with internal dimensions of around seventeen metres east to west and just over fourteen metres north to south. The earthen bank survives most visibly between the south-west and north-east, where it still carries appreciable height; elsewhere it has been reduced to an external scarp of around 1.2 metres. The bank is widest and tallest on the northern side, reaching up to 5.3 metres across, and the original entrance, a narrow gap of 1.2 metres, faces east-south-east. The site was recorded on Ordnance Survey six-inch maps in both 1840 and 1916, marked with the hachuring convention used to indicate earthworks, which suggests it was recognisable as a feature of the landscape long before any formal archaeological record was compiled.
