Explore Hassan II Mosque in Casablanca, Casablanca

The Hassan II Mosque is Casablanca's premier attraction—if you can only see one thing in the city, let it be this! It's the largest mosque in Morocco, sitting on the edge of the Atlantic Ocean. Its large complex includes a museum, baths, Koranic school, library, and a prayer room supported by 78 granite and marble pillars. As the second-largest mosque globally, the prayer room holds 25,000 people, and the outside courtyard can accommodate an additional 80,000 worshippers.

Inaugurated in 1993, the mosque's 650-foot (200-m) minaret is the tallest structure in Morocco and the tallest minaret in the world. As you walk up to the mosque, admire the impressive exterior and surrounding area, then head inside. What makes this mosque even more unique is that non-Muslims can enter, which isn't common in Morocco.

Once inside, admire the ornate design with beautiful green hues and mosaic tiles. The lavish interior blends wood, marble, and carved stone together with arched and ornamented ceilings. The roof is covered with emerald green tiles, and at night, the mosque glows orange, illuminated by lights that reflect on the ocean's waves. Artisans from across Morocco contributed to this superb architectural masterpiece.
