Built in 1501-06, this was the second great mosque complex to be founded in the city. The first, the Fatih Mosque, was destroyed, which makes Beyazıt the oldest imperial mosque in town. In effect, it's the architectural link between the Byzantine Haghia Sophia - the obvious inspiration - and thegreat, later Ottoman mosques such as Süleymaniye.
The sultan for whom it was built, Beyazit II, is buried at the back of the gardens. Still in use, the mosque is full of market traders at prayer times. Outside is the Sahaflar Carsisi (book bazaar), where Sufi booksellers tout travelogues and novels in many diffferent languages.
