While most people immediately think of the movie going by the same name, Casablanca is much different than it was portrayed in the film that popularized the name. These days it is the industrial and economic center of Morocco, and while it is the country's largest city, is also one of the least appealing things to see and experience while in Morocco. However, that's not to say there isn't plenty to see and do in the city, because places like The King Hassan II Mosque, the Corniche, and the Shrine of Sidi Abderrahman are definitely eye-openers in their own right, it's just that when compared to some of the other things that can be experienced in Morocco, Casablanca is sometimes lacking.
Perhaps the reason the Casablanca is a little less than what most people expect is the fact that the city has graduated into a cosmopolitan center of modernity, and much of what made the city such a romantic place in the early parts of the 20th century and before have been traded in exchange for modern amenities and economic importance. It is difficult to find a true Moroccan experience in Casablanca, although the section of Old Medina still has some traditional Moroccan markets. For the most part, Casablanca is the ultimate look at modern Morocco, and the overall style feels very European, despite the Moorish themes in architecture in some of the buildings. Almost all of modern Morocco is less than 50 years old, making this a fairly new town that is difficult to distinguish from any other major European or American city, and while you can see certain sections of the city where the Moroccan underbelly peeks through, most of the nightclubs, restaurants, and hotels will offer you such a Western experience that you probably won't even realize you've left your home country.
