Chefchaouen

Chefchaouen or Chaouen (Arabic: شفشاون/الشاون‎‎, Shafshāwan) is a city in northwest Morocco. It is the chief town of the province of the same name, and is noted for its buildings in shades of blue.
Chefchaouen is situated in the Rif Mountains, just inland from Tangier and Tetouan. The city was founded in 1471,as  a small fortress which still exists to this day, by Moulay Ali Ben Moussa Ben Rached El Alami (a descendant of Ibn Machich and Idris I, and through them, of the Islamic prophet Muhammad) to fight the Portuguese invasions of northern Morocco.Along with the Ghomara tribes of the region, many Moriscos and Jews settled here after the Spanish Reconquista in medieval times.In 1920, the Spanish seized Chefchaouen to form part of Spanish Morocco. Spanish troops imprisoned Abd el-Krim in the kasbah from 1916 to 1917, after he talked with the German consul Dr. Walter Zechlin (1879–1962). (After defeating him with the help of the French, Abd el-Krim was deported to Réunion in 1926.) Spain returned the city after the independence of Morocco in 1956.
Chefchaouen or Chaouen, as it is often called by Moroccans, is a popular tourist destination because of its proximity to Tangier and the Spanish enclave of Ceuta. The name refers to the shape of the mountain tops above the town, that look like the two horns (chaoua) of a goat. "Chef Chaouen" derives from the Berber word for horns, Ichawen. There are approximately two hundred hotels catering to the summer influx of European tourists. One distinction possessed by Chefchaouen is its blue-rinsed houses and buildings.
Chefchaouen is a popular shopping destination as well, as it offers many native handicrafts that are not available elsewhere in Morocco, such as wool garments and woven blankets. The goat cheese native to the area is also popular with tourists.
The countryside around it has a reputation for being a prolific source of kief. The Chefchaouen region is one of the main producers of cannabis in Morocco. Hashish is subsequently sold all over town, but is mostly the domain of native Chaouenis. A nearby attraction is the Kef Toghobeit Cave which is one of the deepest caves in Africa.
Chefchaouen's blue walls are a popular subject of interest. There are several theories as to why the walls were painted blue. One popular theory is that the blue keeps mosquitos away, another is that Jews introduced the blue when they took refuge from Hitler in the 1930s. The blue is said to symbolize the sky and heaven, and serve as a reminder to lead a spiritual life.
The growing tourist industry is geared especially towards Spanish tourists, who are especially numerous during great Catholic feasts like Semana Santa and Christmas.
