Dutch windmill reconstruction of a grainmill that stood on the citywalls of Leiden. In the 17th century, most automatic production was done by wind power. Windmills like these would probably work day and night with a good wind to get most production done.
This type is called a Standerd-mill, because it stands on a large stand. You are still able to find windmills like these in the Netherlands. Some of which have been renovated and are working again.
