The Groenendijk Mill is an 17th century corn mill, which originally stood in the hamlet of Oliekot, and was moved to the village Kloosterzande in 1781, where it was used as an oil mill. The mill is now owned by Hulst County, and has been recently restored. The Groenendijk Mill is open to the public every Saturday, and there is a small shop inside the mill which sells a variety of freshly ground cereal products.
