To an untrained eye it reads as little more than a natural rise in the ground, but successive generations of mapmakers tracked its decline and recorded what it once was: a lime kiln, a structure used to burn limestone at high temperatures to produce quicklime, which farmers spread on acidic soils to improve fertility. By the time the Ordnance Survey revised its 25-inch maps in 1897, the kiln was already annotated as disused.

The story of this particular structure can be pieced together through the layered record of Irish mapping. The kiln first appears on the 1840 edition of the Ordnance Survey's 6-inch map, placing its active life somewhere in the earlier nineteenth century, when lime burning was a common agricultural practice across Munster. By the time the Cassini edition of the 6-inch map was produced, the cartographers rendered the site using hachured earthwork notation, the small radiating lines surveyors used to indicate a mound or earthen rise, signalling that the kiln had already collapsed into a heap of rubble. Caimin O'Brien, who compiled the site record uploaded in October 2021, also notes that a grass-covered mound of the collapsed structure remained clearly visible on Digital Globe aerial photography taken between 2011 and 2013, confirming the feature has survived, in degraded form, into the present century.

The site lies in Glenanair East, a townland in County Limerick, though no public access point or waymarked route is recorded for it. As with many such agricultural remnants, the mound is likely on private farmland, and any visit would require the landowner's permission. Those with an interest in vernacular industrial archaeology will find the feature most legible in low winter light or after a frost, when subtle ground-level variations in old pasture tend to show up more clearly. The OSi historical map layers, freely accessible online through the Ordnance Survey Ireland viewer, allow anyone to trace the kiln's recorded presence across nearly two centuries of cartography, overlaying the 1840, 1897, and later editions to watch the feature shift from working structure to annotated ruin to unmarked earthwork.
