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
In 1574, after a great fire destroyed the kitchens, Mimar Sinan was entrusted by Sultan Selim II to rebuild the damaged parts of the palace. Mimar Sinan restored and expanded not only the damaged areas, but also the Harem, baths, the Privy Chamber and various shoreline pavilions.
By the end of the 16th century, the palace had acquired its present appearance. The palace is an extensive complex rather than a single monolithic structure, with an assortment of low buildings constructed around courtyards, interconnected with galleries and passages. Few of the buildings exceed two stories. Seen from above, the palace grounds are divided into four main courtyards and the harem. The first courtyard was the most accessible, while the fourth courtyard and the harem were the most inaccessible. Access to these courtyards was restricted by high walls and controlled with gates. Apart from the four to five main courtyards, various other small to mid-sized courtyards exist throughout the complex. Estimates of the total size of the complex varies from around to .
