Beyazit II, son of the Conqueror, is remembered kindly by history as one of the more benevolent of sovereigns, and indeed, in Turkey, he has been elevated to a saint. The mosque and complex bearing his name is the oldest surviving imperial mosque in the city (its predecessor, the Fatih Camii, succumbed to an earthquake and was reconstructed in 1766). The complex was built between 1501 and 1506 using materials taken from Theodosius's Forum of Tauri, on which it is built.

Again, the architect of Beyazit Camii looked to the Ayasofya, employing a central dome buttressed by semidomes and a long nave with double arcades, although the mosque is half the size of the church. The Beyazit Mosque also borrows elements from the Fatih Mosque, imitating the system of buttressing and the use of great columns alongside the dome. Thanks to Sultan Beyazit II's patronage, the Ottomans found a style of their own, which served as a bridge to later classical Ottoman architecture. The sultan, who died in 1512, is buried in a simple tomb, decorated in mother-of-pearl and stained glass, at the back of the gardens.
