Ashton windmill is a tower mill in Chapel Allerton, Somerset, England. Its tower is over 7.5 metres (25 ft) high with stone walls that are 60 cm (2.0 ft) thick. The sails are 13 m (43 ft) across and used to be covered with canvas. The last millstones were 1.2 m (3.9 ft) across and the millstones used to grind wheat for flour and beans for cattle food. It is now preserved, having been given to Bristol City Museum in 1966 and is owned by Sedgemoor District Council, and maintained by volunteers.
