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.
Tokat
The most important landmark is Tokat Castle, an Ottoman citadel with 28 towers on a rocky hill overlooking the town. Vlad the Impaler (Count Dracula) was imprisoned in one of its dungeons. Other sights include the remains of several Greek Orthodox churches and a cathedral, the Garipler Mosque dating to the 12th century, the Ali Paşa Mosque (16th century), and the Gök Medrese (Pervane Bey Darussifasi), which was constructed in 1270. It was founded as a school of theology, and is now converted into a museum, housing archaeological finds from the area.
