Chefchaouen, ou Chaouen “blue town,” is famous for being one of the prettiest places on the planet. For people who love color, it’s truly a blue dream, with its bright cerulean-hued architecture tucked within the hills of northwest Morocco. Row after row of buildings in its center are covered in blue paint in shades ranging from baby blue to aquamarine. The unusual coloring was introduced by Jewish refugees who arrived during the 15th century Spanish Inquisition, they believed that the more one looks at anything blue, the more they think about heaven. It also seems to help repel mosquitoes, as the insects perceive it as clear flowing water, which they aren’t attracted to. It does feel as if you’re swimming when walking down the flights of blue painted steps surrounded by the blue ceilings and blue walls. No cars are allowed on its narrow streets, where vendors sell their wares in open, traditional markets. The high walls block out the intense rays of the sun to create cool, shady areas, and from just about anywhere in the Chefchaouen medina, you can look up to see the mountain peaks above.
