The Cloverleaf Mill is a traditional saw mill located on Kalverringdijk in the town of Zaandam. The mill was built in 2004 by Ru Pos, following many years of planning and effort. The Cloverleaf Mill is ran by ’The Cloverleaf Foundation’. The Cloverleaf Mill is open to the public on the first Saturday of each month. Visitors can learn about the project and the goals of the foundation, and see the mill in operation.
