Otterton Water Mill is set beside the River Otter in Devon.
The manor and its mill were given by King Henry V to the nuns of Syon Abbey.
At the Dissolution the manor was sold to Richard Duke, in whose family's possession the mill remained for 200 years.
The watermill was restored in 1977 by Desna Greenhow, and has been operated again since, remaining functional today.
The mill hosts a yearly event with a "Portable Antiquities team" to examine archaeological finds made in the area.
