The interest lies precisely in that absence. A gallaun is a standing stone, one of the solitary upright megaliths scattered across the Irish landscape, some dating back thousands of years and raised for purposes that remain largely unclear. This particular one, overlooking Kenmare Bay from a north-facing shelf of rough pasture, has vanished entirely. No stump, no socket, no scatter of rubble to suggest where it fell.

What we know about it comes almost entirely from a single cartographic record. The 1846 Ordnance Survey six-inch map, produced during the first comprehensive mapping of Ireland and still an invaluable document for tracking features that have since disappeared, marked an upright stone at this location and named it plainly as Gallaun. By the time the site was formally assessed, that stone was gone. Whether it was removed for use in field walls, buried, or simply toppled and absorbed into the rough ground over the intervening decades is not recorded. The name Killaha places the site within a townland on the Iveragh Peninsula, in a part of Kerry where the land rises quickly from the bay into open mountain.
