At Milltown Britton in County Tipperary, a ringfort that has been largely ploughed away continues to exert this kind of influence, the surrounding farmland having adjusted itself around an enclosure that is now little more than a gentle swell of earth in otherwise flat pasture.

Ringforts, also known as raths, were enclosed farmsteads built predominantly during the early medieval period, roughly between the fifth and twelfth centuries, and they survive across Ireland in their thousands, in varying states of preservation. This particular example sits on level ground with a channalised stream running west-north-west to east-south-east about ten metres to its south-west. Centuries of ploughing have reduced it considerably, yet the circular form remains legible: the raised area measures roughly thirty metres across in both directions. The most intact section is the north-west sector, where a scarp still rises about a quarter of a metre and a faint trace of an external fosse, a defensive ditch, can be made out at around two and a half metres wide and twelve centimetres deep. By 1982, when the site was formally visited and recorded by Cahill, the bank was already heavily denuded and the fosse largely infilled and waterlogged, with the overall diameter measured at that point as thirty-three metres. To the east, the ringfort meets a field boundary whose ditch has become waterlogged, and it is here that the boundary makes its slight but deliberate kink outward, accommodating the old enclosure without quite swallowing it.
