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 Twin Kiosk / Apartments of the Crown Prince ("Çifte Kasırlar / Veliahd Dairesi") consists of two privy chambers built in the 17th century, at different times. The building is connected to the palace and consists of only one storey built on an elevated platform to give a better view from inside and shield views from the outside.
