Mapledurham House- Watermill

There is much more to Mapledurham than just the house. A short distance behind the manor, on the banks of the river, is a restored water mill, the only working mill on the Thames. There has been a mill here since at least the 11th century, but the oldest part of the current mill building dates to the 15th century. The medieval mill was enlarged in the 17th century.
