Ironmacannie Mill

Most of the surviving structure dates to the nineteenth century, but the oldest parts of the building are late eighteenth-century, and it was built on the site of a much older mill. It was designated a Category A listed building in 1971; its designation describes it as being "remarkable for the survival of most of the internal gearing and machinery". In 1990, consent was granted to convert the building for use as domestic accommodation, while preserving the historic gear and machinery in-situ; work began shortly afterwards, and the building is currently used as holiday accommodation, marketed as The Hidden Mill.

The mill stands on a site about 2.4 mi south of Balmaclellan, on the north bank of the Shirmers Burn. It is a three-story L-plan building, with rubble masonry made of locally mined whinstone. The windows are plain, and mostly in the south-east wall. Two cast iron waterwheels survive, fed via its mill races by water from a dam some 80 m north of the mill. The larger wheel formerly drove the mill's three grinding stones, while the smaller one operated the bellows for the mill's kiln. There is now a micro hydro generator, providing power for the building.
