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.
Toompea
The much-rebuilt Toompea Castle – consisting of the czarist era governor's palace, walls and towers of the medieval fortress, the expressionist parliament building dating from 1922, plus a few other buildings – now houses the Estonian Parliament. The facade of the classicist governor's palace dominates "Lossi plats" ("Castle square"), where the Orthodox Alexander Nevsky Cathedral overtops it. The cathedral, nowadays the main church of the Estonian Orthodox Church of Moscow Patriarchate, has become for tourists somewhat of a symbol of Tallinn due to its exotic look, while the opinion of Estonians about it is rather ambiguous. The Lutheran Cathedral ("Toomkirik") from which the name Toompea was originally derived, is now the seat of the Estonian Evangelical Lutheran Church and has perhaps best retained a medieval look among the buildings of Toompea. Most of the buildings in Toompea date from the 18th and 19th centuries. While the Small Castle has generally preserved its shape, nothing but a few fragments remain of the Great Castle's walls and towers.
