Priston Mill And Attached Pond, Dam And Walls

Priston Mill is a watermill located on an ancient site, with structures dating from the late 18th century to the early 19th century. The building is constructed of rubble with freestone dressings and quoins, featuring ashlar and double Roman tile roofs with raised coped verges. It has four storeys and two windows, all of which are three-light. The outer two windows are shuttered and have segmental heads with keystones. The ground floor includes a central door and double doors to the right, all situated under two gables topped with obelisk finials.

The north elevation has three storeys and two windows, similar to the front but only two-light on the left. A flight of three steps leads up to similar double doors under a 20th-century lean-to porch, while on the right, steps lead down to an opening for the wheel pit. The south elevation features four storeys, with the top floor being blank and three windows, all two-light casements. To the right, one window is blocked and another half-blocked, while to the left is the opening for the wheel pit.

The west elevation shows only two storeys with similar details, including windows above and doors below. The remainder of this elevation, including former window heads, is obscured by the pond dam walls. These walls, made of ashlar, are located adjacent to the mill and about eight metres westward on the north side, while the rest flanking the long, thin pond are of rubble.

Inside, there is a large cast iron overshot pitchback wheel that drives the complete works. A wallower on an oak shaft drives a great spur wheel, which in turn drives a pair of stones above. The hoist traps remain, and all machinery is in working order.
