Kairaouine Mosque and University, Fes (must see)

The Kairaouine complex (pronounced "kare-a-ween") is a sight to behold, yet for non-Muslims, it often remains shrouded in mystery. One of the main entrances is at the end of the Talâa Kbira, offering a glimpse of the vast courtyard inside, although it may not fully convey the immense size of this complex. Muslims are welcomed inside for prayer and to explore the university grounds, though classes may be in session at times. It's common for worshippers to guide Muslim visitors around, showcasing the marvels of this truly remarkable structure.

Founded in 857 by Fatima al-Fihri, daughter of a wealthy refugee from Tunisia, the mosque has undergone several expansions and renovations over the centuries. The most significant expansion occurred in the 12th century under the Almoravids, who enlarged the prayer halls and footprint of the mosque to accommodate up to 22,000 worshippers.

Adjacent to the mosque, the Kairaouine University, sometimes touted as the oldest university globally, was initially established as a "medersa" alongside the mosque. While it wasn't officially recognized as a university until it joined Morocco's state educational system in 1963, UNESCO acknowledges it as the oldest continuously operating educational institution in the world, far ahead of those in Europe.

Venturing into the heart of the old Medina to catch a glimpse of this legendary institution is well worth it, following which you can pause for a quick bowl of bissara to recharge. While non-Muslims may have restricted access, they can still appreciate the traditional courtyard with its washing area (reserved for men) and the prayer area. The mixture of indoor and outdoor spaces make the complex truly amazing.
