So that’s windmills, but what about the barns? Why are they red? Well, some have suggested it’s to stop cows getting lost when they’re coming home. That can’t be it, though, because cattle can’t tell the difference between red and green. Another hypothesis is that they’re red because Scandinavians used the color, trying to make the barns look as though they were constructed from bricks.
