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
On November 30, 2011, Libyan ex-police and revolutionary Samir Salem Ali Elmadhavri, apparently copying the act of Norwegian extremist Anders Behring Breivik, attempted to massacre hundreds of tourists visiting the Palace in the early hours. Stopped at the Bab-i Humayun entrance by the Palace Guards, he opened fire on soldiers and security guards, injuring Private Şerafettin Eray Topçu and security guard Mehmet Ballıcı. After that he entered the main courtyard of the palace but was forced to retreat and search shelter in the entrance by Palace Guard force. After a gunfight lasting over one hour he was killed by Turkish Police SWAT teams. The incident sparked discussions about Palace security, because a foreigner was able to enter the Palace in broad daylight, during working hours, while carrying two hunting rifles. More security measures were put in place at the Palace entrance the day after the incident.
