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
The building where the arms and armor are exhibited was originally one of the palace treasuries ("Dîvân-ı Hümâyûn Hazinesi / Hazine-ı Âmire"). Since there was another ("inner") treasury in the Third Courtyard, this one was also called "outer treasury" ("dış hazine"). Although it contains no dated inscriptions, its construction technique and plan suggest that it was built at the end of the 15th century during the reign of Süleiman I. It subsequently underwent numerous alterations and renovations. It is a hall built of stone and brick with eight domes, each 5 x 11.40 m.
