The Hassan II Mosque is Casablanca's defining landmark and one of the largest mosques in the world. Built partly over the Atlantic and completed in 1993, it is also one of the few mosques in Morocco that welcomes non-Muslim visitors on guided tours. Here is what to know before you go.
The best of Casablanca
The scale
About. The mosque holds tens of thousands of worshippers across its prayer hall and esplanade, and its minaret rises about 210 metres — among the tallest in the world. Much of the structure sits on a platform over the sea.
Built over the Atlantic
About. Commissioned by King Hassan II and completed in 1993, it was designed by French architect Michel Pinseau. Part of the prayer hall extends above the ocean, echoing a Quranic verse about God's throne upon the water, and a glass floor section lets light onto the sea.
Guided tours for visitors
Visiting. Non-Muslims can enter only on official guided tours, which run at set times during the day outside prayer hours. Tours take you into the vast prayer hall and often the ablutions level below; buy tickets at the on-site office and arrive early as times are limited.
Craftsmanship to look for
Visiting. Note the hand-carved cedar ceilings, intricate zellij tilework, Venetian-glass chandeliers and Moroccan marble and granite — the building was a showcase for thousands of the country's master artisans.
Dress & etiquette
Practical. Dress modestly: shoulders and knees covered for everyone; you will remove your shoes before entering the prayer hall (a bag is provided). Photography is generally allowed inside; follow your guide's directions and remain quiet and respectful.
Best time & exterior
Practical. Even outside tour hours the exterior and esplanade are spectacular, especially at sunset when the stone glows and the minaret light shows. Morning tours tend to be cooler and quieter.
