Koutoubia
The city's landmark, the minaret of the venerable Koutoubia Mosque was named after the 12th century souk el koutoubiyyin, the bazaar of the book-traders. The hall-type mosque has 17 aisles and 112 columns covering a total floor area of 5400 sq.m (58,000 sq. ft) and is thus among the largest of its kind - 25,000 faithful can say their prayers within it. At the end of the prayer hall is an ornately carved minbar (pulpit), said to have come from Cordoba; its donor is believed to have been the Almoravid sultan Ali ben Youssef (1107-1143).

The square minaret, which wasn't completed until the reign of Yacoub el Mansour (1184-1199), was the direct model for the Giralda in Sevilla and the Hassan Tower in Rabat. It is considered the ultimate structure of its kind. The tower is 69 m (221 ft) in height, its lateral length 12,8 m (41 ft). The tower is adorned with four copper globes. According to legend, they were originally made of pure gold, and there were once supposed to have been only three. The fourth was donated by the wife of Yacoub el Mansour as compensation for her failure to keep the fast for one day during the month of Ramadan. She had her golden jewelry melted down, to fashion the fourth globe.
