The most attractive mosque in Istanbul, as well as in Turkey, was designed by a pupil of Sinan, Sedefkar Mehmet Ağa, between 1609 and 1616. Sultanahmet Mosque is as grand as, and similar in design to, Süleymaniye, and features an unrivaled selection of İznik tiles. Until 1998, when the six-minaret Sabancı Central Mosque was inaugurated, Sultanahmet was the unique mosque in Turkey possessing six minarets.
The mosque is situated in Istanbul's historical area of Sultanahmet near hippodrome and Hagia Sophia.
