The picturesque scenery surrounding the Tour de France must help promote countryside tourism. The riders cycle past castles and quaint towns. What I love most are the old windmills. These elegant workhorses of the grain farms are each unique. Looking through the extremely comprehensive lists of windmills in Wikipedia, you realize that although Holland is the country most associated with windmills, they were an important fixture in most European countries. Even if you exclude the modern windpumps and turbines, the different rotation devices, sails, machinery, and construction materials make for a wide variety of windmill designs.
