Interior of the Sultan Ahmed Mosque (Sultan Ahmet Camii). The most important element in the interior of the mosque is the mihrab, which is made of finely carved and sculptured marble, the adjacent walls sheathed in ceramic tiles. To the right of the mihrab is the mimber, or pulpit, where the Imam stands when he is delivering his sermon at the time of noon prayer on Fridays or on holy days. The mosque has been designed so that even when it is at its most crowded, everyone in the mosque can see and hear the Imam.
