Tour by miller J. Slingerland

The Molenviergang (set of four mills that work together) was built between 1786 and 1801. It is the only working set of 4 mills in the world. In reality, it consists of three mills that work together, and one for draining. 

One of the four mills, the Putmolen, is open to the public. The miller, Johan Slingerland, organizes a comprehensive tour of the mill to groups of 10 or more persons, only on appointment.
