Notice the building to the left of the windmill tower in the night picture, with the vanes of the windmill facing away. That building is in the same position to the windmill tower in the day shot, but now the vanes of the windmill are facing forward.
If the pictures were taken from opposite sides of the windmill tower, the building would be seen to be on the other side of the tower.
Point taken. I hadn’t considered that.
Good question. That would be an interesting feat to engineer the mechanism that would allow the top to pivot, all made out of wood. I'd love to see the innards of one of those. Now, you got my curiosity up.....
