At Lahardaun in County Clare, an old quarry and its associated lime kiln have all but disappeared, swallowed by a modern dwelling and the tidied pasture that surrounds it. What once was an irregular, oblong cutting measuring roughly 51 metres along its longer axis has either been backfilled or now forms the deep cutting excavated behind the house. The lime kiln, a D-shaped structure that once sat immediately to the east of the quarry, has been removed entirely.

Lime kilns were a common feature of the Irish rural landscape, used to burn limestone at high temperatures to produce quicklime, which was then spread on fields to reduce soil acidity or used in mortar for building. The pairing of a quarry with a kiln in the same location was practical and typical; stone could be extracted and processed on the spot. At Lahardaun, both features were recorded on the 25-inch Ordnance Survey map, with the kiln explicitly named as disused. By the time the 6-inch edition of 1921 was published, the same features appeared without any label at all, suggesting they had already been out of use for some years and were fading from local significance. What the maps captured, in other words, was not a working operation but its afterimage.
