D. Sehzade Mosque (Sehzade Mehmed Camii, the Prince's Mosque). The Sehzade complex was commissioned by Ottoman Sultan Süleyman (Süleyman the Magnificent, Qanuni, the Lawgiver (reg. 1520-1566 CE) to commemorate his favourite son Sehzade Mehmed (1520-1543 CE ) upon his early death in 1543 when he was killed aged 22 while returning to Istanbul after a victorious military campaign in Hungary
E. Bayezid II Mosque (Beyazidiye Camii), commissioned by Ottoman Sultan Bayezid II, and the second large imperial mosque complex to be erected in Istanbul after the Conquest
F. Fatih Mosque: an Ottoman imperial mosque located in the Fatih district of Istanbul. It was one of the largest examples of Turkish-Islamic architecture in Istanbul and represented an important stage in the development of classic Turkish architecture. It is named after Ottoman sultan Mehmed the Conqueror, known in Turkish as Fatih Sultan Mehmed, the Ottoman sultan who conquered Constantinople in 1453
G. Sokullu Mehmet Pasha Mosque. Designed by the Ottoman imperial architect Mimar Sinan in 1571/1572 for the grand vizier Sokullu Mehmet Pasha (the husband of one of the grand-daughters of Sultan Suleiman the Magnificent, Princess Esmahan)
H. Suleymaniye Mosque and Kulliye. Built on the order of Sultan Süleyman (Süleyman the Magnificent), with designs by Mimar Sinan. The construction work began in 1550 and the mosque was finished in 1558. The design of the Süleymaniye also plays on Suleyman's self-conscious representation of himself as a 'second Solomon.' It references the Dome of the Rock, which was built on the site of the Temple of Solomon, as well as Justinian's boast upon the completion of the Hagia Sophia: "Solomon, I have surpassed thee!" The Süleymaniye, similar in magnificence to those structures, asserts Suleyman's historical importance. The structure is nevertheless smaller in size than its older archetype, the Hagia Sophia
P. Beyazit Tower (Beyazıt Kulesi): possibly the site of the later fire-watch tower in the courtyard of Istanbul University's main campus on Beyazıt Square
