The Rockanje Mill was built in 1718. It is a working corn mill. The mill was bought by John Klapmuts in 1740, and stayed in the Klapmuts family for many years. The current owner is Mr J. Clock. The mill was restored in 1988, and is in use throughout the year. Tours of the mill are available by appointment. The Rockanje Mill is currently in a deteriorating condition, and more restoration work is needed.
