Enjoy a private tour to the White Towns of Andalusia. The White Towns of Andalusia are a series of towns in southern Spain, mostly within Sierra de Grazalema Natural Park. All of the villages are characterized by white washed walls and red or brown tiled roofs. Some say that these villages paint the white house to ward off the intense summer heat that affects mainly the towns along the Sierra de Grazalema. But keep whitewashed houses is a very ancient custom in the Mediterranean to disinfect the environment in the plague epidemic period. The lime mixed with water produces a high heat kill any microorganism. Therefore, people living in cities with houses "whitewashed" ended up escaping more disease than those who did not. Today times have changed, but the tradition is still alive, somehow, marking the time to paint the facades (whitewashed). So much so that in some pueblos blancos, you can paint the exteriors of homes without taxes.
