Chefchaouen Blue Medina

The medina of Chefchaouen is painted in shades of blue that have no single explanation — theories include Jewish settlers who associated blue with heaven, a colonial-era pest deterrent, or simply a mayor in the 1930s who liked the color. None of the theories are conclusive. The blue is real. It covers every surface, shifts with the light through the day, and makes the city look like an idea rather than a place.
