That map records it as a subcircular field, roughly 25 metres across, the kind of modest earthwork that once dotted the Irish countryside in considerable numbers and now survives, where it survives at all, as little more than a grassy bank.

Enclosures of this type are among the most common, and most overlooked, features of the Irish archaeological landscape. They range in date from the Bronze Age through to the early medieval period, and were used variously as farmsteads, cattle enclosures, or defended homesteads. Without excavation it is rarely possible to say which function any particular example served. At Driminidy, the southern bank is the one detail that remains visible, suggesting the rest of the perimeter has either eroded or been absorbed into the surrounding land. The 1903 OS six-inch map, one of the most detailed surveys of rural Ireland ever undertaken, was thorough enough to record it, even if the enclosure was already fading from view by then.
