One of the finest Islamic buildings in North Africa and rewards closer inspection. Non Muslims are not permitted into the prayer hall, but the doors are open to allow you to view inside. Access to the main courtyard is available to all. The columns throughout the complex were taken from Carthage, the wooden ceiling from Lebanese cedar wood. In the courtyard, there are indents into the floor with varying sizes for camel or dromedary hoofs, or human feet, for washing before prayers. On the tiny platform in the middle of the courtyard, there is also four black pins on a board that tells the prayer times by the sun. Facing the prayer room, on one of the left columns is also a last black pin marking the night prayer by moonlight.
