Topkapı Palace
Following the end of the Ottoman Empire in 1923, Topkapı was transformed into a museum by a government decree dated April 3, 1924. The Topkapı Palace Museum is administered by the Ministry of Culture and Tourism. The palace complex has hundreds of rooms and chambers, but only the most important are accessible to the public today, including the Ottoman imperial harem and the treasury, called "hazine" where the Spoonmaker's Diamond and Topkapi Dagger are on display. The museum collection also includes Ottoman clothing, weapons, armor, miniatures, religious relics, and illuminated manuscripts like the Topkapi manuscript. The complex is guarded by officials of the ministry as well as armed guards of the Turkish military. Topkapı Palace is part the Historic Areas of Istanbul, a group of sites in Istanbul that were added to the UNESCO World Heritage Site in 1985.
Topkapı Palace
The Dormitory of the Royal Pages ("Hasoda Koğuşu") houses the Imperial Portraits Collection ("Padişah Portreleri Sergi Salonu") was part of the Sultan's chambers. The painted portraits depict all the Ottoman sultans and some rare photographs of the later ones, the latter being kept in glass cases. The room is air-conditioned and the temperature regulated and monitored to protect the paintings. Since the sultans rarely appeared in public, and to respect Islamic sensitivity to artistic depictions of people, the earlier portraits are idealisations. Only since the reforms of the moderniser Mahmud II have realistic portraits of the rulers been made. An interesting feature is a large painted family tree of the Ottoman rulers. The domed chamber is supported by pillars, some of Byzantine origin since a cross is engraved on one of them.
