Windmills, Consuegra, Spain…
The windmills are tall cylindrical towers capped with dark cones and four big “sails” that move with the wind. In days gone by, farmers would haul their grain to these windmills where the structures harnessed the power of the wind to grind grain.
The windmills and the skill to operate them were passed down from fathers to sons. Windows placed around the tower of the windmill provide great views today. But that was not their original use. From these windows, the miller could keep watch on the shifting winds. When the winds changed, the miller would have to move the tiller beam to turn the mill. If he didn’t a sudden strong wind could strip the sails, rip off the top and the whole building could be destroyed by a gusty wind.
