Casablanca's landmark building, the Hassan II Mosque is a lavish symbol not only of the city, but also of Morocco itself. This modern mosque (finished in 1993) doesn't do things by halves. The decoration detail covering every centimetre of the mammoth 2 ha site took 10,000 artisans to complete. Intricately carved marble pieces, vibrant mosaics and zellige tile details pay tribute to traditional Islamic architecture, and yet still manage to feel contemporary.
