This one is notable for what does not. On an east-facing slope just west of Brookpark House in mid Cork, a standing stone once occupied a patch of pasture with no visible trace remaining today. It has been removed entirely, leaving behind only the paper record of its existence and the question of when, and why, it disappeared.

The stone's documentary history is brief but telling. It does not appear on the Ordnance Survey's six-inch map of 1842, which suggests either that it was overlooked by the original surveyors or that it had not yet been recorded as a feature of note. By 1904, however, it had been marked on a revised six-inch map and labelled "Gallaun", the anglicised form of the Irish word "gallán", a term used to describe a single upright standing stone, typically of prehistoric origin. The gallaun tradition spans thousands of years in Ireland, with individual stones erected for purposes that remain debated, variously interpreted as boundary markers, astronomical indicators, or monuments connected with burial. Whatever this particular stone meant to the people who raised it, it was standing, or at least recorded, in the early twentieth century, and is now gone.
