The Beyazidiye Mosque (1501–1506) in Istanbul begins the Classical period in Ottoman architecture, in which the great Imperial Mosques, with variations, resemble the former Byzantine basilica of Hagia Sophia in having a large central dome with semi-domes of the same span to the east and west. Hagia Sophia's central dome arrangement is faithfully reproduced in three Ottoman mosques in Istanbul: the Beyazidiye Mosque, the Kılıç Ali Pasha Mosque, and the Süleymaniye Mosque. Three other Imperial mosques in Istanbul also add semi-domes to the north and south, doing away with the basilica plan: Şehzade Camii, Sultan Ahmed I Camii, and Yeni Cami. The peak of this classical period, which lasted into the 17th century, came with the architecture of Mimar Sinan. In addition to large Imperial mosques, he produced hundreds of other monuments, including medium-sized mosques such as the Mihrimah, Sokollu, and Rüstem Pasha Mosque and the tomb of Suleiman the Magnificent. Süleymaniye Mosque, built in Constantinople (modern Istanbul) from 1550 to 1557, has a main dome 53 meters high with a diameter of 26.5 meters. At the time it was built, the dome was the highest in the Ottoman Empire when measured from sea level, but lower from the floor of the building and smaller in diameter than that of the nearby Hagia Sophia.
