On the northern slopes of Corrin Hill, overlooking Tralee Bay and the coastal plain below, the Ordnance Survey once recorded a gallaun, the Irish term for a standing stone, one of the thousands of solitary upright stones erected across Ireland during prehistory, their precise purposes still debated. It occupied rough, marshy ground with a long view out over the bay, the kind of position these stones often seem to have been placed with some deliberate intention, whether as boundary markers, ritual sites, or something else entirely.

The stone was documented in J. Cuppage's 1986 archaeological survey of the Dingle Peninsula, the Corca Dhuibhne survey, which catalogued the extraordinary density of prehistoric and early Christian remains across that part of Kerry. By the time that record was being revisited, however, the land around Corrin Hill had been reclaimed, the marshy ground drained and brought into agricultural use. The stone did not survive the process. Where the gallaun once stood, there is now nothing to see.

This is not an uncommon fate. Land reclamation has removed countless unprotected field monuments across Ireland, particularly smaller standing stones that had no immediate visual prominence and sat on ground considered agriculturally marginal. The Mountoven gallaun is now known only through its mark on an OS map and a single survey entry, a placeholder for something that existed for perhaps three or four thousand years before disappearing quietly in the late twentieth century.
