Dome of the Blue Mosque in Istanbul: The Sultan Ahmed Mosque was commissioned by Sultan Ahmed I in 1609 and built by Sinan disciple Mehmet Ağa until 1616, a year before the Sultan's death, it is a major work of Ottoman architecture. After the secularization of Hagia Sophia, barely 500 meters away, it was Istanbul's main mosque until July 2020, since July 24, 2020, the Hagia Sophia is again the main mosque of the city.
