The bank survives to just under a metre in height, eroded now but still tracing out a perimeter roughly 60 metres from north to south and 63 metres from east to west. That is not a small enclosure. Whatever it once contained or defined, it was built at a meaningful scale.

Earthen enclosures of this kind are scattered across the Irish landscape, and they come in many forms: some are the remains of ringforts, the farmstead enclosures that were the basic unit of early medieval rural life in Ireland; others are later in date, associated with Norman manorial activity or with land management practices whose origins are harder to pin down. The sub-rectangular shape here is worth noting, since true ringforts tend toward the circular, and a more angular outline can sometimes point toward a different period or function. The fact that the interior rises toward the centre, combined with that heavily ridged and uneven surface, suggests the ground has been significantly disturbed or built upon at some point, though what structures may once have stood there is not recorded. The place-name Frenchfurze itself is intriguing, containing what may be a reference to a Norman settler family, a common enough element in Cork townland names given the intensity of Norman colonisation in the county from the twelfth century onward.
