The Privy Room of Sultan Murad III The Privy Room of Sultan Murad III is as important in terms of Ottoman architecture as the Harem itself. It was designed and built by the chief architect Sinan in 1579 on the order of the sultan and used as the sultans’ official and private apartment. Its walls are covered with 16th-century İznik tiles. One of the walls has been inscribed, in white writing over blue, with the Verse of the Throne from the Qur’an’s Surah al-Baqarah (2:255). On the lower level of the room is a bay window constructed by Sultan Ahmed I (r. 1603-17) and a pool dated 1579.
