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 Sultan or the Valide Sultan was able to follow deliberations of the council without being noticed from a window with a golden grill. The window could be reached from the imperial quarters in the adjacent Tower of Justice ("Adalet Kulesi"). The window is mentioned for the first time in 1527 by the scholar Celalzade Mustafa Çelebi: "His Majesty [...] had built a high throne and a lofty loggia above the outer Council Hall where viziers sat, inventing a veiled window overlooking the Council Hall below. From this window, his Noble Excellency sometimes watched the events of the divan, checking the truth of affairs." The Tower of Justice ("Adalet Kulesi") is located between the Imperial Council and the Harem.
