Map of Casablanca, Ville du XXème siécle, carrefour d'influences
The coordinates shown for all tentative sites were produced as a community effort. They are not official and may change on inscription.
I visited this tentative WHS in April 2018. In my opinion, the French-colonial design still present in Casablanca is not of OUV and would definitely not contribute anything which is missing from the WH list.
On the other hand, Casablanca is a pleasant stopover between the two WHS of El Jadida and Rabat but mostly to appreciate the impressive Hassan II Mosque (photo) by the Atlantic Coast.
I visited Morocco in December 2010, and ended my trip in Casablanca, where I stayed at Hôtel Maamoura, one of the city's many Mauresque (a blend of French-colonial design and traditional Moroccan style) buildings. The best meals in Casablanca were the fresh oysters from the stalls in the Central Market and Rick's Cafe, touristy but very well done (and where I was able to rewatch Casablanca, whose final five minutes are among the best in movie history) (www.rickscafe.ma/). I ended my trip to Morocco with a visit to Hassan II Mosque.
