Scattered across and around it are several small islands, each carrying some trace of human use. One of them takes its name from an industry rather than a saint or a family: Kiln Island, named for the kind of structure once used to burn limestone and produce quicklime for agricultural improvement or building mortar. A lime kiln, typically a stone-built furnace fed with alternating layers of fuel and broken rock, was a common enough feature of the Irish rural landscape from the seventeenth century onward, but to have one positioned on a lake island is a less ordinary arrangement.

Beyond the name itself and its industrial implication, the documentary record for this particular site is thin. The name alone, though, is worth pausing over. Islands on Irish loughs were put to many uses over the centuries, from early monastic settlement to the keeping of cattle out of reach of thieves, and occasionally to small-scale industrial activity where water access made the transport of heavy materials more practical than overland routes. Lough Carra itself has a longer history of human presence: the lake and its surrounds have yielded evidence of activity stretching back through the medieval period and considerably further. Kiln Island sits within that broader landscape of accumulated use, its name a quiet record of a more recent, workaday past.
