On the 1944 to 1945 revision of the OS six-inch map, a hachured feature appears in the undulating pastureland of Fahy, County Galway. Hachuring, the cartographer's shorthand for a depression or earthwork, tends to signal something worth investigating: a ringfort, perhaps, or the sunken outline of a long-vanished structure. This one turned out, on inspection in 1984, to be a disused and overgrown quarry.

The gap between the map and the ground visit is itself a small piece of local history. Whatever stone was extracted here, the working had long since ceased, and the vegetation had been quietly reclaiming the cut for decades by the time anyone went to look. Because the quarry dates to after AD 1700, it falls outside the period covered by formal archaeological assessment, which concerns itself with earlier remains. That boundary means a site like this tends to slip between categories, too recent for one kind of record and too minor for another, leaving it to moulder in pastureland without much official attention.
