A ringfort once stood on a north-facing slope here in County Cork, a circular earthen enclosure roughly thirty metres across, the kind of raised and ditched farmstead that thousands of early medieval Irish families built between roughly the fifth and twelfth centuries. By the time the Ordnance Survey mapped the area in 1842, it was still legible enough to be drawn as a hachured circle on their six-inch sheet. Sometime in the following three decades, it was gone.

The record of its disappearance is unusually precise. A researcher named Broker, writing in 1937, noted that the fort had stood in a field known as the Quarry field and had been levelled during the tenure of someone referred to only as Philpott, around 1870. A separate account by Bowman in 1934 placed this ringfort among three single-ramparted forts on land belonging to a Miss Victoria Allen, all of them already destroyed by that point. A single-ramparted ringfort, the most common type in Ireland, typically consisted of one earthen bank and external ditch enclosing a circular area used for habitation and the protection of livestock. The Knocknageeha example was not exceptional in form, but the combination of a dateable act of clearance, a named landowner, and two independent researchers documenting the loss within a few years of each other gives this otherwise vanished site an unusual documentary afterlife. Most levelled ringforts disappear without even that much.
