FIGURE 6.31 The Maghreb subregion (Northwest Africa). (A) A street in Chefchaouen, Morocco, a city built in 1471 by Moorish exiles from Spain to defend northern Morocco against Portuguese invasion. The city, known for its blue-washed houses, was invaded by Spain in 1920 and held until Morocco’s independence from France in 1955, when it was returned to Morocco. It is now a popular tourist destination for Europeans, given its proximity to the city of Ceuta, which is still held by Spain. Courtesy Sally Walton/Flickr Vision/Getty Images
