These mills harnessed the flow of local streams or rivers to drive a waterwheel, which in turn powered millstones to grind grain, typically oats or wheat, into flour or meal. For the communities that depended on them, they were as essential as any building in the parish.

The specific history of this particular mill, including when it was built, who operated it, and how long it remained in use, is not yet fully documented in the public record. What can be said is that corn mills in Connacht were most commonly associated with the eighteenth and nineteenth centuries, a period when landlord-driven agricultural improvement and rising grain demand prompted construction or expansion of milling infrastructure across the region. Many fell silent after the Famine or with the gradual shift away from tillage farming in the west during the later nineteenth century, leaving behind shells of cut stone, collapsed mill races, and the occasional intact millstone half-buried in a field boundary.
