Sultan Ahmed Mosque
Several mosques commissioned by the Ottoman dynasty have similar measurements to the Hagia Sophia, including the Süleymaniye Mosque and the Bayezid II Mosque. Ottoman architects preferred to surround the central dome with four semi-domes rather than two. There are four semi-domes on the Sultan Ahmed Mosque, the Fatih Mosque, and the New Mosque (Istanbul). As in the original plan of the Hagia Sophia, many of these mosques are also entered through a colonnaded courtyard, although the courtyard of the Hagia Sophia no longer exists.
