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.
