Near the Weaver's stream in Kilgobnet, County Kerry, there was once a ringfort, the kind of roughly circular earthwork enclosure, known in Irish as a rath, that farmers and chieftains built across Ireland during the early medieval period, typically between the sixth and twelfth centuries. Thousands of these survive across the Irish landscape. This one does not. Around 1980, a farmyard was constructed on the site, and any remaining trace of the original enclosure was lost in the process.

The fort had been recorded on the second edition of the Ordnance Survey map, where its subcircular outline was clearly enough defined to be plotted. Locally it was simply known as a 'fort', the common term still used in rural Ireland for these earthworks, which were long associated in folklore with the supernatural and generally left undisturbed. Its position was just to the west of the Weaver's stream. By the time archaeological interest formally caught up with it, through the survey of the Iveragh Peninsula compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996, the monument was already gone. What the survey could document was essentially an absence, a location on a map where something once stood and nothing now remains.
