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.
Dunster church was shared for worship between the monks of Dunster Priory and the parishioners, however this led to several conflicts between them. One outcome was the carved rood screen which divided the church in two with the parish using the west chancel and the monks the east. It was restored in 1875–77 by George Edmund Street. The church has a cruciform plan with a central four-stage tower, built in 1443 with diagonal buttresses, a stair turret and single bell-chamber windows. Dunster, in Exmoor National Park, has many listed buildings including 200 Grade II, two Grade I and two Grade II*.
