Iznik pottery
The ceramic collection of the Topkapi Palace includes over ten thousand pieces of Chinese porcelain but almost no Iznik pottery. Most of the surviving Iznik vessels are in museums outside Turkey, but examples of the city's tile production exist in numerous cities throughout Turkey, such as İstanbul, Bursa, Edirne and Adana. In Istanbul examples of Iznik tiling can be seen in mosques, tombs, libraries, and palace buildings, such as the Rüstem Pasha Mosque, the Sokollu Mehmet Pasha Mosque, the tomb of Selim II in the Hagia Sophia complex, and certain buildings of the Topkapı Palace complex such as the Circumcision room and the Baghdad Kiosk.
Topkapı Palace
Surrounded by high walls, the First Courtyard ("I. Avlu" or "Alay Meydanı") functioned as an outer precinct or park and is the largest of all the courtyards of the palace. The steep slopes leading towards the sea had already been terraced under Byzantine rule. Some of the historical structures of the First Courtyard no longer exist. The structures that remain are the former Imperial Mint ("Darphane-i Âmire", constructed in 1727), the church of Hagia Irene and various fountains. The Byzantine church of Hagia Irene was used by the Ottomans as a storehouse and imperial armoury. This courtyard was also known as the Court of the Janissaries or the Parade Court. Court officials and janissaries would line the path dressed in their best garbs. Visitors entering the palace would follow the path towards the Gate of Salutation and the Second Courtyard of the palace.
