It is not ancient enough to attract the attention of archaeologists, and not recent enough to be remembered by anyone in particular. It exists in a quiet administrative gap, too modern for one branch of heritage, too forgotten for another.

What we know of it comes from a single cartographic moment. The 1944 to 1945 revision of the Ordnance Survey six-inch map recorded a hachured feature at this location, the small radiating lines used by mapmakers to suggest a hollow or depression in the terrain. When someone went to look in 1984, the feature turned out to be a disused quarry, post-dating 1700 AD. That inspection confirmed its existence and its rough age, and then, in a sense, closed the file. Quarrying of this era was common across rural Ireland, where local landowners and tenants extracted limestone, sandstone, or whatever the local geology offered, for building walls, houses, roads, and field boundaries. The Dooros quarry was almost certainly one of these working sites, modest and practical, opened when stone was needed and abandoned when it was not.
