Chefchaouen is a city in Morocco that's famous for its blue hue. While it was founded in 1471, it didn't get its distinctive color until 1492, when it received an influx of Jews escaping the Spanish inquisition, who brought a tradition of painting buildings blue.
Half a millennium later, the tradition persists in Chefchaouen's Old City, which is now a popular tourism and shopping destination.
The city's grown since the 1400s, but it's Chefchaouen's Old City that maintains the blue tradition.
The city itself is near the northern tip of Morocco.
The tradition of painting everything blue dates back to the Jewish community that settled there in the 15th century.
