Stretton Watermill is a working historic watermill in Stretton, Cheshire, England. It is owned and administered by Cheshire West and Chester Council. The mill is recorded in the National Heritage List for England as a designated Grade II* listed building and the mill machinery is considered to be of national importance. History The earliest record of the mill is when it changed ownership in 1351. In the 16th century the mill was owned by the Leche family. The oldest surviving structure of the building date from 1630, at which time it was timber-framed and had a single breastshot wheel. The cobbled ground floor surface is thought to pre-date the 1630 building. In 1770 the mill was extended by William Leche, the roof was raised and the thatched roof replaced by slates. The timber framing was encased in weatherboarding and sandstone, and an overshot wheel was added. This work is commemorated by an inscribed stone on the west corner of the building. In 1852 the timber breastshot wheel was replaced by a similar type of wheel in cast iron. The mill finally ceased operation in 1959. The mill machinery was restored by Cyril & John Boucher during 1975–7, with partial funding from the Science Museum. The mill has been a museum since 1977. Description The mill is constructed on a timber-framed core, and is cased in weatherboarding and sandstone. There is a brick extension, and a chimney in stone and brick. The roofs are slated. The mill is in two storeys, with an attic for storing grain. The windows are all casements, some with shutters. There are two working waterwheels, one on the outside, the other inside the building. The external wheel is a timber overshot wheel, which drives largely 18th-century wooden machinery. The internal wheel is in cast iron, and is breastshot; it drives Victorian mainly cast-iron machinery. The upper storey, which contains four millstones, is entered by a steep internal stairway, and the grain loft is accessed by a ladder. Outside the mill are stone steps leading up to the mill dam, and a stone-lined millrace with a sluice. Present day The site operates as a museum, picnic area and visitor centre. It is open to the general public on advertised days during April–September between 1pm and 5pm, and whilst access to the site is free, there is a small charge for a guided tour of the mill's interior
