De Os, Historic windmill in Zaanse Schans, Netherlands.
De Os features a roof height of 33.3 meters and a wingspan of 26.6 meters, making it stand among the largest windmills in the region.
The structure replaced an earlier wooden post mill from 1400, and in the 1930s, a diesel engine was added to maintain production during low wind periods.
The windmill represents Dutch water management traditions and agricultural heritage, serving as both a functional mill and a preservation of historical techniques.
Visitors can access the windmill through guided tours, where they learn about traditional milling processes and the mechanics of wind-powered operation.
During World War II, the structure served as a German observation post before being restored to its original function in the early 1970s.
