Early Quranic manuscripts
The Topkapi manuscript is an early manuscript of the Quran dated to the early 8th century. This manuscript is kept in the Topkapi Palace Museum, Istanbul, Turkey. It was wrongly attributed to Uthman Ibn Affan (d. 656), but judging from its illumination, the Topkapi manuscript does not date from the period (mid 7th century) when the copies of the Caliph Uthman were written.
Topkapı Palace
The main street leading to the palace is the Byzantine processional Mese avenue, known today as "Divan Yolu" (Council Street). This street was used for imperial processions during the Byzantine and Ottoman era. It leads directly to the Hagia Sophia and turns northwest towards the palace square to the Fountain of Ahmed III.
