The Oudendijk Mill is a 17th century water mill located on Dorpsweg in the town of Hornet. The mill was built in 1688, as one of the mills that would serve ’The Land of the Six Mills’ polder. The mill was bought by the Foundation for the Conservation of Mills in the Alblasserwaard and Vijfheerenlanden after it was decommissioned in 1970. The mill was restored in 1984, and re-opened by M. W. Schakel, who was then serving as the Mayor of Hornaar.
