Founded in the 11th century, Marrakech is a city steeped in history, as evidenced by several of its most famous monuments and buildings. Here are five examples of Moroccan architecture in Marrakech that shouldn't be missed. 1. Tombeaux Saadiens. Only a few hundred yards from Les Borjs de la Kasbah, these highly decorated tombs form one of the most important heritage sites in Morocco. One of the few remaining vestiges of the important Saadien dynasty, they date from the time of Sultan Ahmad al-Mansur (1578-1603) although were sealed off on the orders of Alaouite Sultan Moulay Ismail who wanted all traces of the Saadien dynasty to be destroyed. Untouched for more than two centuries, the tombs were uncovered in 1917 and restored by the national 'Beaux-Arts' service. Due to their intricate decoration, a clear indication of the opulence of the time and a perfect example of the beauty of Islamic art, the tombs are a major attraction for visitors to Marrakech and should be high on your list of 'what to see in Marrakech'. Expect domed ceilings, intricately carved marble pillars, cedar wood ceilings and, most notably, extensive use of exquisite mosaic decoration. 2. Mansouria Mosque. Built by Yaqub al-Mansur, the Mansouria Mosque is also known as the Kasbah Mosque, being just 100 yards from the monumental gate into this fortified southern part of the Marrakech medina, Bab Agnaou. Although access to the interior is not open to non-Muslims, one can admire the impressive architecture of the building now restored to its former glory following an extensive facelift.
