On the 1932 edition of the six-inch OS map covering Lehanagh in County Galway, one such marking sits quietly among the pastureland and bogland, looking for all the world like it might indicate something ancient. When someone finally went to look in 1983, the reality was more modest but no less interesting: an overgrown, disused quarry pit, its edges softened by decades of encroaching vegetation.

The quarry dates to after 1700, which places it in the era of improving landlords, estate building, and the expanding demand for local stone that accompanied agricultural change across the west of Ireland. Quarry pits of this kind were often opened to supply material for field walls, farmhouses, or estate infrastructure, and many were worked only briefly before being abandoned when the immediate need passed. Without a specific record of who opened this one or why, the pit itself is the main document, sitting in its gentle landscape as a faint trace of that workaday past. The gap between the map's creation in 1932 and the ground inspection in 1983 is its own small story: more than fifty years during which the hachured symbol on the paper outlasted any living memory of what the feature actually was.
