It sports six minarets representing six key aspects of Islamic belief. Four of them are 107.1 meters tall, a tribute to the Seljuk Turks' victory in eastern Turkey at Manzikert in 1071 against the Byzantine army which opened Anatolia to Turkish settlement.
Its central dome hangs 72 meters above the ground, representing the 72 nations living in the city. The second dome -- with a diameter of 34 meters -- represents Istanbul's official license number.
Sixteen names of Allah are inscribed on the inner walls of the dome, symbolizing the number of states founded by Turks throughout history.
