Beautifully perched between two mountain peaks on the northern tip of Morocco, Chefchaouen was kept locked away from the rest of the world for centuries and is painted entirely in shades of blue. This blue city was a refuge for Jewish minorities fleeing from Europe in the 15th century, and around this time, residents began painting buildings and sidewalks various shades of blue. In Judaism, blue represents the sky and the heavens, reminding everyone to live a life full of spiritual awareness.
