Welcome to Casablanca. The largest city in Morocco, Casablanca is a modern city with major French influence. For an architectural treat, visit the popular Hassan II Mosque and admire its exquisite craftsmanship. Sitting pretty on an outcrop over the Atlantic Ocean, the Hassan II Mosque is estimated to house 25,000 worshippers inside, with additional room for 80,000 in its courtyard. Unique to Morocco, Hassan II is one of few mosques where non-Muslims are permitted to enter. Feast your eyes on the intricate marblework, wood and stone carving, and gilded cedar ceilings. Explore Parc de la Ligue Arabe and check out the Casablanca Cathedral (no longer in use) for a fine example of mid-19th-century "Mauresque" architecture (a mix of European art deco and Moorish style). Visit the Old Medina (old quarter), the only part of the city pre-dating the French protectorate, before touring the Hobous, or new medina. Built in the 1930s by the French.
