Somewhere in level pasture on the edge of a south-west-facing slope in north Cork, a ringfort once stood, its circular bank and surrounding fosse intact enough to be mapped not once but twice across the span of a century. By the late 1970s, however, it was gone, levelled around 1977 according to local memory. What remains, if you know to look, is a low rise in the ground, possibly the faint ghost of the old bank.

A ringfort, or rath, is one of the most common monument types in the Irish countryside: a roughly circular area enclosed by an earthen bank and ditch, typically dating from the early medieval period and used as a defended farmstead. At Kilgilky, the site appears on the 1842 Ordnance Survey six-inch map, though at that stage it was recorded not as a clear earthwork but as an irregular area planted with trees, suggesting the original shape had already become difficult to read on the ground. By the time the 1905 and 1937 editions of the same map series were produced, the ringfort was shown more explicitly, hachured as a circular enclosure with a fosse, the surrounding ditch, still visible. A field boundary running from the south-south-east to the north-east respected the site, skirting around it rather than cutting through, the kind of quiet accommodation between farming and ancient monument that kept so many such sites intact for generations. That accommodation eventually ended around 1977, when the earthwork was levelled, leaving the landscape without the feature that maps had faithfully recorded for well over a century.
