On the shore, just beyond the northern tip of the medina of Casablanca (old town), the Hassan II mosque dominates the whole city. Completed in 1993, it is the second largest mosque in the world, covering an area of two hectares with the world’s tallest minaret (200 meters high). The prayer room can accommodate 25,000 faithful, while the courtyard (which has a retractable roof) can accommodate 80,000 more. A surprisingly intricate decoration covers every inch of surface. The location, right on the tip of the rocky bay above the ocean, is quite dramatic. Non-Muslims can visit the mosque on guided tours, which start at the entrance to the mosque entrance several times a day.
