Castleton Waterwheel Museum is run by a local group of volunteers who over the past 25 years have rescued the waterwheel and its house from serious neglect. The wheel, 26 feet in diameter having steel rims, 72 steel buckets, and a cast iron rim-gear, is unique in having three leats providing water in high breast shot array; it also has a system of ventilated buckets invented by William Fairbairn in the early part of the 19th century.

In 1876 a Hindley Steam Engine was added and we now have a similar engine in a new building that will run under steam on open days.

It was installed to provide clean water for the inhabitants of Sherborne in 1869 and ran until 1959.
