Kinderdijk. (dutch for children dike)

This windmill can be found in Kinderdijk and I liked this one because of the wind going through the reed while the mill stands still in the back.
Kinderdijk is a village in the Netherlands and is situated in a polder. To drain the polder, a system of 19 windmills was built around 1740. This group of mills is the largest concentration of old windmills in the Netherlands.

riddle: When is the miller without his head in the mill?
