At Ballyconnell in County Kerry, a ringfort, or rath, a type of circular earthwork enclosure used as a farmstead during the early medieval period, roughly between the fifth and twelfth centuries, occupies exactly that position. No bank, no ditch, no rise in the ground gives any hint that something once stood here. The site survives only because cartographers recorded it before it disappeared entirely.

The enclosure was documented on the Ordnance Survey maps of 1841 to 1842 and again on the 1898 revision, which means it was still legible as a feature in the landscape during the nineteenth century. At some point after that second survey, it was lost. The southern sector had already been compromised by a field bank running east to west cutting across it, the kind of incremental agricultural reshaping that has quietly erased countless such monuments across Ireland. The site sits in the same field as a neighbouring ringfort to its north-west, which suggests this was once a more substantial settled area than the current farmland implies. Today, no surface trace survives.
