On the 1932 edition of the Ordnance Survey six-inch map, a hachured feature near Lattoon in County Galway hinted at something worth investigating. Hachures, the short radiating lines cartographers used to indicate slopes or hollow features, can mark anything from ancient earthworks to far more modest disturbances in the landscape. When someone finally went to look in 1983, they found an overgrown, disused gravel pit, post-1700 in date and thoroughly unremarkable by the standards of formal archaeology.

The site sits in that particular category of place that is interesting precisely because of how little fanfare surrounds it. It spent the better part of half a century as an unexplained symbol on a map, the kind of mark that invites speculation before the mundane truth arrives. Gravel extraction of this kind was a routine part of rural land management in early modern and modern Ireland, supplying material for roads, farm tracks, and building work. The date threshold matters here: because the pit is of post-AD 1700 origin, it falls outside the scope of prehistoric and early historic archaeology, which concerns itself with older layers of human activity. The 1983 inspection confirmed it was simply a hollow in the ground, long since given over to vegetation.
