In the marshy, low-lying pastureland of Lisnagry in County Galway, there is a pit that spent decades as nothing more than a hachured mark on a map, the kind of cartographic shorthand that suggests a hollow or earthwork without quite committing to an explanation.
When someone finally went to look in 1983, they found a quarry, modest and post-medieval, the sort of working hollow that would once have supplied local stone or gravel for a nearby farm or road, and has since been quietly swallowed by damp ground and grass.
The feature appears on the 1920 edition of the Ordnance Survey six-inch map, a series produced with remarkable detail across Ireland from the nineteenth century onwards. Hachuring, a technique using short radiating lines to indicate slopes or depressions, was a standard tool for surveyors of the period, though it could leave the nature of a feature genuinely ambiguous to later readers. The inspection in 1983 resolved the ambiguity, identifying the pit as a quarry of post-1700 date. That dating places it outside the scope of formal archaeological classification, which generally concerns itself with features from earlier periods, and so the site sits in a quiet administrative gap, documented but not catalogued as heritage in any official sense.
