At a T-junction near An Bhinn Bhán on the Dingle Peninsula, a ringfort once stood whose circular earthen bank is now gone from the landscape entirely, surviving only as a name, Lisín an Chomhraic, and as a ghostly outline on the first edition of the Ordnance Survey map. A ringfort, or rath, was an enclosed farmstead of the early medieval period, typically defined by one or more circular earthen banks and ditches; this one was univallate, meaning it had a single such enclosure.

By the early nineteenth century, when the Ordnance Survey fieldworkers passed through and recorded their observations in the name books for the townland of Garfinny, the fort was already in a ruinous state. Part of the bank was still visible on each side of the road, which suggests the road itself had been cut directly through the enclosure at some point, bisecting what had once been a continuous circular form. J. Cuppage, whose 1986 archaeological survey of the Corca Dhuibhne region documented the site, noted that the southern bank of the east-west road at this junction is slightly curved, and that this curvature may roughly follow the original line of the enclosure. It is a slender thread of continuity: the road bending almost imperceptibly to the shape of something that ceased to exist as a recognisable structure long before anyone thought to protect it.
