On the Ordnance Survey maps, a circular enclosure is marked at An Baile Dubh on the Dingle Peninsula in County Kerry, its outline implying a structure with edges, a boundary, a presence. In reality, no visible remains survive. The enclosure is a cartographic ghost.

Until 1983, the site retained at least a physical memory of itself: a circular, level platform on a north-west facing slope at the lower northern end of the ridge that separates the Glennahoo and Scorid rivers. Such a platform would once have been the earthen footprint of a ringfort or similar enclosed settlement, the kind of circular enclosure, typically defined by an earthen bank or fosse, that was once a common feature of early medieval Irish farming landscapes. That platform was levelled in 1983, removing the last legible trace of whatever had stood there. The site was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a publication that captured a number of sites already in the process of disappearing from the landscape at that time.

What remains is the map mark, the river names, and the ridge line itself, a place that can be located by its geography even when the archaeology has been erased entirely.
