This one, cut into the land of the Deerpark townland in Coshlea Barony, Co. Limerick, is absent from the Ordnance Survey's meticulous six-inch mapping of 1840, yet by 1897 it had earned its own annotation on the twenty-five-inch edition, marked simply as a quarry and shown as an irregular area defined by a scarp, a steep near-vertical face left when rock or earth is cut away. Somewhere in that fifty-seven-year gap, someone opened the ground here, extracted whatever the land offered, and eventually moved on.

The site sits in what is now reclaimed pasture, roughly 90 metres east of the townland boundary with Duntryleague, with a separate enclosed feature recorded about 65 metres to the west. Compiled by Fiona Rooney and uploaded to the record in October 2021, the site has been formally reclassified as a quarry of post-1700 date, placing its working life within the era of improving landlords, road-building schemes, and the steady demand for local stone that shaped much of rural Ireland's built landscape from the eighteenth century onwards. The Coshlea area, tucked into the southern part of County Limerick, would have seen its share of such small-scale extraction, supplying material for field walls, farmsteads, and minor infrastructure that rarely attracted much documentary attention.

By the time aerial imagery from Digital Globe was captured between 2011 and 2013, the quarry had become overgrown, sitting on the edge of a mixed conifer and deciduous plantation. Google Earth imagery confirms the same picture. There is no marked trail or interpretive signage, and the site is not one that announces itself easily from the road. Anyone curious enough to seek it out would be navigating by grid reference across agricultural land, with the tree line as the principal landmark. What you would find is less a dramatic void in the earth than a quiet, scrubby hollow, the kind of place that rewards patience and a decent pair of boots rather than any particular expectation of spectacle.
