What Is the Hassan II Mosque?



The Hassan II Mosque a masterpiece of Moroccan and Andalusian architectural styles sits dramatically on the Atlantic coastline in Casablanca. Completed in 1993 under the direction of King Hassan II, it was designed by French architect Michel Pinseau and built by thousands of Moroccan artisans.
Location & Significance in Casablanca
This mosque is not just spiritually significant; it’s a civic landmark and one of the most photographed sites in Morocco. Positioned partly over the Atlantic Ocean, its seaside location was chosen to reflect a Qur’anic verse that suggests God’s throne was built upon water.
Architectural Features
The Hassan II Mosque blends traditional craftsmanship with modern engineering. Its intricate zellige tilework, carved cedar wood ceilings, and hand-crafted marble floors highlight Morocco’s artisanal heritage. The structure also features a retractable roof and is engineered to withstand earthquakes—a great fusion of beauty and innovation.
How Big Is Hassan II Mosque?
One of the biggest points of pride for the Hassan II Mosque is its capacity and expansive footprint.

Physical Footprint
Set over a complex that spans approximately nine hectares (22 acres), the mosque isn’t just about worship space. It also includes facilities like a library, madrasa (Islamic school), water features, and beautifully landscaped gardens.
Is Hassan II Mosque the Biggest Mosque in the World?
No the Hassan II Mosque is impressive, but it isn’t the biggest mosque in the world.
While it welcomes tens of thousands of worshippers and boasts an enormous footprint, several mosques exceed it in terms of capacity and overall size. For example:
Al-Masjid al-Haram in Mecca and Al-Masjid an-Nabawi in Medina are larger both in capacity and sacred scope, especially during Hajj and other major religious events.
The Great Mosque of Algiers (Djamaa el Djazaïr) in Algeria, inaugurated in recent years, has a combined capacity that surpasses Hassan II.
So while Hassan II remains one of the largest mosques globally, it’s not technically the biggest mosque in the world by worshipper capacity.
Is Hassan II Mosque the Biggest Mosque in Africa?
This is where the story gets interesting.
For many years, the Hassan II Mosque was widely described as the largest mosque in Africa, and sources even still sometimes make that claim.
However, in recent years, the Great Mosque of Algiers (Djamaa el Djazaïr) has taken that title with its capacity of around 120,000 worshippers and a towering 265-meter minaret.
So the short answer:
- Hassan II Mosque is one of the largest and most iconic mosques in Africa.
- But it is no longer the biggest mosque on the continent that honor goes to the Great Mosque of Algiers.
