Description
Trehudreth Mill is a 17th-century water mill constructed from stone rubble, featuring a slate roof with hipped ends. The building has a rectangular plan and is built into a bank, with bedrock forming the base of the rear wall. Originally, an overshot wheel was located on the left-hand (north) gable end, but it has since been removed. The entrance is situated at the front right, with external steps leading up to the original loading door on the right-hand gable end.
The mill stands two storeys tall and has a single-storey outshot added in the 19th century to the left, also made of stone rubble and topped with a lean-to slate roof. The granite doorframe on the right features a chamfered lintel and jambs with straight cut stops. The first floor includes the remains of a mullioned window near the centre and another window to the left. There are external stone rubble steps on the right-hand gable end.
Inside, some machinery is still present, including one direct drive wheel and one geared wheel, along with two pairs of stones on an oak table hurst. Notably, this mill contains one of the few surviving timber wallowers in Cornwall.
