The one at Teernahillane in West Cork does the opposite, sitting on level reclaimed bogland as though the landscape itself has been rearranged around it. A rath is an early medieval earthwork enclosure, typically circular, built from a raised bank of earth and sometimes an outer ditch, used as a defended farmstead. This one still rises to a height of 2.8 metres and measures roughly 28 metres across, which makes it a reasonably substantial example, though it has not come through the centuries entirely intact.

The enclosing bank has been partially removed, as has a rectangular section of the interior to the north-northwest, measuring approximately 4.6 by 3.5 metres. That kind of targeted removal often reflects agricultural improvement or drainage work carried out during or after the reclamation of the surrounding bogland, the sort of practical intervention that has quietly altered thousands of earthwork sites across Ireland. The bog itself offers an interesting layer of context: the fact that this ground was once wet and unworkable may well be part of why the rath survived at all, awkward enough to clear that it was simply left standing while the fields around it were gradually drained and pressed into use.
