What was once a circular earthwork enclosure, roughly thirty metres across, now survives as little more than a low rise where the ground meets a field fence. Without knowing what to look for, a visitor would almost certainly walk straight past it.

Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically consisting of a circular bank and ditch enclosing a domestic space. They were built and occupied roughly between the fifth and twelfth centuries, serving as farmsteads for single families or small kin groups. The one at Coneybeg was recorded as a clearly visible circular enclosure on the Ordnance Survey six-inch map of 1842, which means it was still legible in the landscape at that point, though already likely reduced from its original form. At some point after that survey, it was levelled, probably in the course of agricultural improvement, a fate that came to many hundreds of similar sites across Munster as pasture was extended and field boundaries consolidated. The slight rise that persists along the southern field fence is thought to follow the original line of the bank, the last physical trace of a structure that would once have defined how people organised their land and their lives in this corner of Cork.
