The one at Kilnaborris, in County Galway, is recorded as a monument, which places it among the physical remnants of an agricultural economy that shaped rural life across Ireland for several centuries. Mills of this kind ground cereal crops, principally oats and wheat, and their presence in a townland usually signals a community of some size and a degree of local organisation sufficient to build and maintain the infrastructure. That a mill existed at Kilnaborris at all is the kind of detail that rewards the curious, even when the broader story remains, for now, only partially told.
