Morocco's largest city, Casablanca has grown up quickly in the last century and a half, from a small village of just a few thousand to almost four million. Today a thriving commercial and industrial metropolis, Casa (as locals call it) is not overtly touristic, but does have a few visit-worthy sites. The King Hassan II Mosque is the largest in Morocco and has the world/s tallest minaret. Casa's Medina, while smaller than those at Fes and Marrakech, has undergone recent restoration.
