This one offers nothing of the sort. At Kilpatrick in County Cork, a ringfort, or rath, a type of enclosed farmstead typically built during the early medieval period between roughly the fifth and twelfth centuries, has left no visible trace on the surface whatsoever. The pasture rolls on, the slope continues northward, and there is nothing to suggest that a circular enclosure of around 32 metres in diameter once sat here, sheltering a household and its livestock behind a raised earthen bank.

What we do know comes from a single source of some age: the Ordnance Survey six-inch map of 1842, which recorded the enclosure at a time when at least some remnant must have been legible in the landscape. By the time any modern fieldwork was carried out, even that had gone, absorbed into the working farmland on the north-facing slope of an east-west ridge. The site sits in the broader tradition of the rath, the most common monument type in the Irish countryside, yet this particular example has been, in a sense, thoroughly erased, surviving only as a cartographic ghost.
