Description
Newhall Mill is a corn mill, now used as a gallery and store, dating from the early 19th century. It is constructed of stone rubble and features a slate roof with gable ends. The building has a rectangular plan and originally housed at least one overshot wheel at the front, which has since been removed. The entrance leads directly onto the stone floor at the front elevation, while the lower ground at the rear has an entrance onto the meal floor. The mill comprises a meal floor, stone floor, and loft.
The exterior has a two-storey elevation at the front and a three-storey elevation at the rear. There are remains of two wheel shafts on the front elevation, likely for overshot water wheels. A ramp leads over the pit to the entrance, which has a plank door located to the right of center.
Inside, most of the machinery has been removed. The mill is believed to have had two pairs of millstones driven by a single spur wheel, with the possibility of a third pair driven by a separate spur wheel. On the meal floor, only the remains of the hurst frame and one pair of millstones, which have been lowered, survive. On the stone floor, one pair of millstones remains in situ.
