Walk the ground above it and you would find nothing to suggest that anything lies beneath, no earthwork, no raised rim, no hollow, just a gentle west-facing slope carrying on as slopes do. Yet the site is real enough, an oval enclosure roughly 40 metres by 30 metres, and its absence from the visible landscape is its most telling feature.

Ringforts, known in Irish as raths or lios, were the enclosed farmsteads of early medieval Ireland, typically circular or oval areas bounded by one or more earthen banks and ditches, used for settlement and the protection of livestock. This particular example was recorded on the Ordnance Survey six-inch map of 1838 under the name Raheen, a diminutive of the Irish word rath, suggesting it was locally recognised and named long before any formal archaeological record. That the cartographers of the 1830s could identify and name it implies the enclosure was still legible in the landscape at that point. At some time since, the earthworks have been levelled entirely, most likely through agricultural improvement, leaving the 1838 map as the clearest surviving evidence of what once stood here.
