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.

The next rooms are the Baths of the Sultan and the Queen Mother ("Hünkâr ve Vâlide Hamamları"). This double bath dates from the late 16th century and consists of multiple rooms. It was redecorated in the rococo style in the middle of the 18th century. Both baths present the same design, consisting of a caldarium, a tepidarium and a frigidarium. Each room either has a dome, or the ceilings are at some point glassed in a honeycomb structure to let the natural sunlight in. The floor is clad in white and grey marble. The marble tub with an ornamental fountain in the caldarium and the gilded iron grill are characteristic features. The golden lattice work was to protect the bathing sultan or his mother from murder attempts. The sultan's bath was decorated by Sinan with high-quality İznik polychrome tiles. But much of the tile decoration of the harem, from structures damaged by the fire of 1574, was recycled by Sultan Ahmed I for decoration in his new Sultan Ahmed Mosque in Istanbul. The walls are now either clad in marble or white-washed.
