Longaller Mill

Longaller Mill is an early 19th-century mill and attached mill house, altered over time. The building is constructed of brick and rubblestone, with rendered surfaces. The mill has a corrugated iron roof, while the rear of the house is covered with Welsh slates. The house section has one and a half bays, and the mill section has three.

The house has a projecting bay with small two-pane casement windows on each floor. The right bay of the house has a 20th-century wood and glass porch masking a six-panel door with glazed upper panels. A sixteen-pane sash window is situated to the left of the door on each floor. There are lateral brick stacks at the left end and at the junction of the bays. The mill has a boarded stable door within a wooden porch on its right end and a sluice with a wooden gate and door above in a round-arched opening on its left end. A mill race has a keyed elliptical-arched opening for a double board door and a cantilevered platform. To the right of the mill race opening are two windows; the left is barred, and the right has a cambered head and a two-light small-pane casement. The first floor of the mill features a double board door on the right and three windows with cambered heads and two-light casements.

The rear of the house has a sixteen-pane sash window on each floor of the right bay. An outshut is attached to the left bay, with a small small-pane window at eaves and a pantile-roofed lean-to beyond. The mill's rear has a triple-arched exit for the sluice and mill race, and two-light small-pane casement windows. The right return of the mill has a keyed elliptical-arched doorway with a double board door, and a boarded door above with a window to the left. In the gable are the circular ends of three tie rods and a keyed round-arched window with small-pane glazing. A similar gable window is present on the left return of the mill, with the left-hand side of the gable hung with Welsh slates.

Inside the mill, iron columns support cross-beams on the lowest floor at the right end. The cross-beams on the next floor are of large scantling and have run-out stop-chamfered spine beams with run-out stops. Wide floorboards are also present. The attic contains five collared principal rafter roof trusses, with collars bolted on, three tiers of staggered butt purlins, and replacement rafters from the late 20th century. Boarded and studded silos are located at the rear. Much of the original mill machinery remains, including a broad iron undershot water wheel with wooden gearing to two sets of stones (one set removed), a crane by Armfield of Southampton, a roller mill for grist by Armfield with red stencilling, a flour dresser by Gardner of Gloucester, a smaller flour dresser by Robinson of Rochdale, a corn cleaner by Armfield, and a corn bin. In the attic, a pulley wheel and chains are used for a sack hoist, with trapdoors on each floor facilitating access.

The site was previously occupied by a fulling and tucking mill until 1823, when the current structure was rebuilt. The mill ceased commercial operation in 1975.
