Ham Mill

Ham Mill is an early to mid 18th century girnal that was converted into a water-powered corn mill in the mid 19th century, with later alterations. It is a large, four-storey, five-bay agricultural building (formerly a girnal) built against a north-facing slope, giving it a three-storey appearance from the south elevation. The structure is made of Caithness flagstone rubble with tooled rubble dressings.

On the principal (north) elevation, there are paired windows in the outer bays, and a 20th century vehicular opening is located off-centre at the ground level, with an additional doorway to the left. The rear (south) elevation features a central timber doorway leading to the second floor, accessed by a forestair, and a wide entrance with a segmental head to the left. There is no water wheel, lade, or other external machinery present.

Inside, there are no internal floors or machinery. The ground level contains the remains of a 20th century concrete grain dryer, along with some evidence of an earlier flagstone floor and timber joists. The roof is made of Caithness slate. A square-plan kiln addition from the mid 19th century, which is roofless, is attached to the southwest.
