A Traveller’s Guide to Morocco's Architectural Gem and the World’s Second Tallest Minaret.

Casablanca’s Hassan II Mosque, Morocco

Casablanca. A city whose name evokes black-and-white romance and high drama, yet whose modern reality is a vibrant, bustling North African metropolis. My own encounter with Casa was a fleeting one—a precious few hours snatched from a long journey—but it was time enough to fall for its coastal energy and, most importantly, to stand in awe before the architectural masterpiece that defines its skyline: the Hassan II Mosque.

The city, though full of charming chaos, felt like a prelude to the main event. My path led me along the coast, and as I approached, the scale of the mosque was almost staggering. It doesn’t just dominate the landscape; it commands the entire Atlantic horizon. Built on a promontory, it appears to rise majestically from the sea itself, a monumental achievement that fulfils the vision of King Hassan II, who stated: “I want to build this mosque on the water, because God’s throne is on the water.”

Even from the outside, the mosque is a sensory experience. The sound of the crushing Atlantic waves provides a natural, spiritual soundtrack to the immense plaza. I walked the perimeter of the vast courtyard, imagining the incredible sight of 80,000 worshippers gathering on these very grounds, in addition to the 25,000 capacity of the indoor prayer hall. The sheer magnitude makes it the second-largest functioning mosque in Africa.

The architecture is a breathtaking symphony of Moroccan, Andalusian, and Moorish styles. You can spend hours simply tracing the intricate detail etched into every surface. The exterior is a rich tapestry of hand-crafted materials, nearly all sourced from Morocco: fragrant Cedarwood from the Middle Atlas, gleaming Marble from Agadir, and sturdy Granite from Tafraoute. It is said that 10,000 master craftsmen from across the kingdom contributed to its construction, a testament to the nation’s artistry. The walls are adorned with pale blue marble and exquisite Zellige tilework, forming complex, colourful geometric patterns that seem to shimmer under the Moroccan sun.

But it is the Minaret that truly steals the breath. Soaring 210 meters (689 feet) into the sky, it was, at the time of its completion in 1993, the tallest minaret in the world (it is now the second). The tower is a colossal work of art, covered in austere green tiling that reflects the light of the ocean. At night, it’s topped by an electronically operated laser beam—a spiritual beacon stretching 30 kilometres toward Mecca, an unmistakable directional light for the faithful.

Though my brief time meant I couldn’t join an internal tour—a definite reason for a return trip!—I learned about the miraculous interior features from the outside. Knowing that the roof above the prayer hall is fully retractable is awe-inspiring. This architectural marvel, which weighs 1,100 tons, can open in just five minutes, allowing worshippers to pray under the daytime sun or the stars at night. The mosque’s placement, with parts of its foundation extending directly into the ocean, makes this connection to the elements profoundly meaningful.

Standing on the edge of the continent, watching the powerful Atlantic meet this immense sacred structure, felt like witnessing a moment of perfect harmony between man and nature. My few hours in Casablanca passed far too quickly, but the sight of the Hassan II Mosque—a glorious, sea-lapped gem—was an unforgettable highlight, a towering testament to faith, craftsmanship, and the enduring grandeur of Morocco.
