Thirston Mill

Thirston Mill is a corn mill dating from the late 18th century with additions made in the early 19th century. It is constructed of squared tooled stone with stone dressings, and has a pantile roof. The south elevation has three storeys and three bays, arranged irregularly. A stable door with a window is positioned to the left of centre, with a 15-pane fixed casement above a slatted section. Two similar windows are on the right and are now within a 20th-century greenhouse. A boarded window and two 16-pane Yorkshire sashes are on the first floor, and three slatted windows on the second. The roof is hipped. Set back to the right is a lower wheelhouse, featuring an opening for the head goit and a coped gable on its right side. The right return of the wheelhouse shows a boarded door and a returned gable coping. The rear elevation has a central, projecting, single-storey wing with a matching gable and a boarded door on the right return. To the right are stone steps leading to a boarded first-floor door. The rear elevation exhibits varied fenestration. Inside, an iron waterwheel remains in situ, along with drive shafts, millstones, and various other fittings.
