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.
Widener Library
At the building's heart are the Widener Memorial Rooms, displaying papers and mementos recalling the life and death of Harry Widener, as well as the
Harry Elkins Widener Collection,
"the precious group of rare and wonderfully interesting books brought together by Mr. Widener",
to which was later added one of the few perfect Gutenberg Biblesthe object of a 1969 burglary attempt conjectured by Harvard's police chief to have been inspired by the heist film"Topkapi".
