Thanks for your reply, Bob.
Don't feel bad about not knowing everything about windmills 😉
That's the nice thing about forums like this one - you can find out about where other people live on this planet
and the (photo) subjects that interest them.
These old windmills in NL can be divided into three main types:
- Water pumping mills (to keep the polderland dry).
- Corn grinding mills (taller, to better catch the wind above the houses in towns).
- Saw mills (especially important for Dutch shipbuilding in previous centuries).
Here's another one from Gouda, a water mill, beautifully restored last year
and they are just adding the last finishing touches in this photo.
