The Kallenbroeker Mill is a historic corn mill in the town of Terschuur. The exact age of the mill is unknown. There is a record of a mill in a list of possessions of the Court of Callenbroek that dates back to 1405, but it is believed that the mill that stands there today was built in the 16th century. The mill is still in working order today, and is used to grind grain for human consumption, as well as animal feed. The mill is open to the public every Saturday.
