Windmills

We saw all sorts of windmills from little ones to modern ones.  They were developed in the 1600s and were used to grind grain, saw logs into planks, move water uphill using an Archimedes screw, and to grind stones for making paint colours.

Below you can see the vertical saw blades attached to the grey unit.  

 People lived inside the windmill- and what a noise they had to live with as the blades rotated  in the wind!
