Prefecture Mechouar de Casablanca was located near Mosque Mohammed V. Well, "mechouar" means a fortified palace with a parade ground.
The building with a very large Arabic gate looks impressive and is guarded by an armed soldier. You can make him a photo if he allows you - simply ask him preferrably in Arab or French language haha. He allowed me to take him alone a photo although I didn't know Arab language (neither French).
By the way, French language is not obligatory at Moroccan schools since early 1990s but almost all children choose just this language. I wonder why? :-)
This building with 50 m (164 ft) impressive, tall clock tower stands on Avenue Hassan II opposite to Mohammed V Place. Hmm.. it is rather impossible to climb up to the top of the tower to admire the views of Casablanca.
It housed the prefectural offices of Greature Casablanca. It was build in 30' of 20th century and opened by Moroccan sultan Mohammed ben Youssef and the president of the Republic of France Albert Lebrun.
This building with Moroccan flag on the top and with fantastic palm trees around Is located on Av. Hassan II just opposite to Place Mohammed V. It Is Palais de Justice = Palace of Justice.
I've found it another great example of modern French-Arab architecture. And as always the area where official (government) buildings stand are the cleanest :-).
A walk around Casablanca will demonstrate clearly that Casablanca was the place that the French colonial authorities gave most attention. And money. The old colonial centre of Casablanca is not small, and refreshingly beautiful. The buildings are of a French version of Arabo-Andalucian architecture, white with soft lines, and often plenty of details.
Corners do often give away the best examples, and happily, the buildings are most of the time in very good condition. The area to explore is south of Avenue des Forces Armées Royales, but of special interest is the Place des Nations Unies, which has the largest structures. Further east and south buildings are less impressive, but equally interesting.
