The Oosterland Mill was built in 1752 to replace a decaying post mill. The mill was originally originally owned by Susanna Maria Loncque, the wife of Mr Van Domburg, mayor of Zierikzee. Today, the mill is owned by the ’Foundation for Mills in the Heerlijkheden, Oosterland, Sirjansland and Oosterstein’, who carried out extensive restoration work on the superstructure of the mill, and replaced the mill’s rods and rigging in 1979. Tours of the mill are available by appointment only.
