The Olle Widde Mill is a traditional corn mill in the town of Ten Boer. It was built in 1828, and was originally used as a rye and barley mill. It was converted to a corn mill in 1927, when it was bought by Mr H. de Boer. The mill has had several owners. The current owner is Mr H D Meijer. The mill is ran on a voluntary basis, and is open to the public, although an appointment is usually required.
