The famous Koutoubia Mosque dominates the skyline of Marrakech. Koutoubia Mosque is 77 meters high, including it’s majestic minaret, and was built in 1158 by the Almohad Caliph Abd al-Mu’min (1094–1163) then completed by his grandson the Almoravid Sultan Yacoub El Mansour in 1195. Caliph Abd al-Mu’min also built the Giralda Tower in Seville and the Hassan Tower in Rabat which was never completed. The towering square Koutoubia minaret in Marrakech is all the more striking because the limestone walls remain undecorated by modern restorers.
