Dunster Working Watermill Dunster Working Watermill Dunster Working Watermill (also known as Castle Mill) is a restored 18th century watermill, situated on the River Avill, close to Gallox Bridge, in the grounds of Dunster Castle in Dunster, Somerset, England. It is a Grade II* listed building. The mill stands on a site where a mill was first recorded in the Domesday Book, but the present building was constructed around 1780. It closed in 1962 but was restored in 1979 and is still used to grind flour. The equipment is powered by two overshot wheels. It is owned and run by the National Trust.
