“Unique in its kind,” announced Napoleon when he arrived at the Zaanse Schans. 600 windmills made up the world’s first industrial area. Today, the 250-year-old windmill park is a fascinating open-air museum. The five biggest windmills in the world are located in the centre of Schiedam. The windmills of Schiedam are over 130 feet (40 m) high and played a major role in gin production.
