Most people give Casablanca two or three hours — visit the mosque, photograph the Corniche, catch the train. What they miss is the downtown Ville Nouvelle, a grid of colonnaded boulevards and ornate residential blocks that were built between roughly 1910 and 1955 and represent one of the most complete surviving examples of French art deco urbanism anywhere in the world. Think Miami Beach or Buenos Aires, but with Hispano-Moorish tile panels and Arabic script worked into the geometry.
The neighbourhood is entirely free to explore on foot, takes two to four hours depending on how deep you want to go, and involves no ticket queues, no crowds and no glossy souvenir stalls. You just walk, look up, and wonder how this city ended up with so many extraordinary buildings that so few visitors bother to see.
This guide gives you the key buildings, a practical walking route, honest time and cost estimates, and advice on whether to go self-guided or with a private architect-guide who knows which doors to knock on.
