Casablanca is a bustling industrial city with very few sites worth seeing in my opinion. The one exception is the Hassan II Mosque. The mosque is located on the coastline of the Atlantic Ocean. The white marble walls have various ceramic inlays and the cedar roof is actually retractable to allow better ventilation. It is the third largest mosque and has the tallest minaret in the world. We admired the décor of both the outside and inside of the mosque, and even visited the washrooms below for ablutions.
