Visiting Casablanca will not be completed without visiting this mosque. A very big mosque with stunning Moroccan architecture. It's also known as the biggest mosque out of Mecca and Medina. The floors at outside are covered by marble. The walls are decorated by colored tiling. It's located next to the sea where you just could sitting around and enjoying the breeze. Since I'm muslim, I didn't pay any enter fee for entering the mosque. They let me in, without asking anything. I did praying, and then capturing beautiful snaps of its architecture interior. It's not so far from Medina, only 15 minutes walking distance.
