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 Sultan or the Valide Sultan was able to follow deliberations of the council without being noticed from a window with a golden grill. The window could be reached from the imperial quarters in the adjacent Tower of Justice ("Adalet Kulesi"). The window is mentioned for the first time in 1527 by the scholar Celalzade Mustafa Çelebi: "His Majesty [...] had built a high throne and a lofty loggia above the outer Council Hall where viziers sat, inventing a veiled window overlooking the Council Hall below. From this window, his Noble Excellency sometimes watched the events of the divan, checking the truth of affairs." The Tower of Justice ("Adalet Kulesi") is located between the Imperial Council and the Harem.
