The word used is 'Gallaun', the anglicised form of the Irish 'galán', a term for a single upright prehistoric stone, usually Bronze Age in origin, whose exact purpose remains debated but which often served as a boundary marker, a memorial, or a point of assembly in the landscape. The problem is that no one can find it. When archaeologists went looking, there was no visible trace of it at all, only rough pastureland where the stone was supposed to stand.

The record of its supposed location comes from J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region, which catalogued the prehistoric and early historic remains of the Dingle Peninsula in considerable detail. That survey placed the gallaun on the eastern slopes of Croaghmarhin, a hillside with an open aspect across the harbour basin below. Whether the stone was removed, buried beneath shifting ground, or was perhaps incorrectly plotted on the original maps is not known. Its absence is the most interesting thing about it now, a placeholder in the archaeological record for something that may or may not have survived into the modern era, or may never have been quite where the maps suggested.
