This is the largest mosque of those found in this Moroccan city. Like all mosques, it is very different compared to Christian churches. Inside, there is no iconography, and Islamic art must be observed in the building: its tall tower, its beautiful doors, its watermarks on the walls. As indicated in the past, even if one of the main pillars of the Koran is tolerance, it is not practised at all in Morocco. Those ve are not Muslims are expressly prohibited to enter these areas, except in the great mosque of Casablanca.
