Tregargus Mill

Tregargus Mill is a former stone-grinding mill, built in the early to mid-19th century, with few later alterations. It operated until around 1965. The structure is made of granite rubble, featuring granite dressings and quoins. The roof was originally covered with slate and shingles, and has gable ends. The mill consists of two rectangular mill houses with a wheel pit in between. An overshot wheel was powered by a leat at the rear, with the tailrace running along the front of the mill houses.

Each mill house is two stories at the front, built into the bank, and single story at the rear. They have symmetrical fronts, each with two round-arched doorways at ground level, complete with keystones, and window openings above. The front is heavily overgrown. The centrally placed wheel is a cast iron wheel with a cast iron launder at the rear. The right gable end features a loading door at upper ground level, with a granite lintel and a small gabled hoist housing above the pulley wheel. The left mill house has two door openings and two small window openings at the rear, along with an unexplained circular stone rubble projection. The right mill house has similar door and window openings. Inside, no machinery remains; only the roof trusses survive, which are halved and bolted at the apex of the principal rafters.
