The example at Outeragh in County Tipperary is a bivallate ringfort, meaning it was defended by two concentric circuits of earthwork rather than the more usual single bank and fosse, a feature that suggests it was a settlement of some local consequence. What makes this particular site quietly interesting is how legibly it wears its own slow undoing. The eastern defences have been worn down to little more than a low scarp, almost certainly because that side of the enclosure sits along a cattle track, the daily passage of animals gradually eroding what centuries of weather had left alone.

The ringfort sits on a north-west-facing slope in undulating pasture, roughly circular in plan, measuring just under thirty metres across in both directions. Its inner bank, where it survives well, rises about 1.24 metres above the fosse, the flat-bottomed ditch that runs between the two earthen circuits, and carries a stone revetment on its interior face that is clearly visible in the western sector. This kind of internal stonework, used to stabilise the bank from within, is a detail that rarely survives so visibly. The outer bank is better preserved along the south and west, where trees have grown up along both circuits and a post-and-wire fence follows the outer edge. The entrance, at the north-west, is three metres wide. In the south and south-west, badger setts have disturbed the fosse and both banks, their upcast soil another layer of gradual, unintentional archaeology layered over the original.
