Privy Room and the Pavilion of the Holy Mantle

The Privy Chamber (Has Oda) also known as the Chamber of the Mantle of Felicity (Hırka-I Saadet Dairesi)  was built under Sultan Mehmet the Conqueror (1451-1481) in the Enderûn Courtyard as private mansion for the Ottoman Sultans.  It is a two-storey typical palace pavilion with a quad space (four-section) layout.  The double space room at the entrance is called the Hall with the Fountain (Şadırvanlı Sofa) due to the marble fountain located under its dome.  The other two parts of the four-section venue consist of two domed rooms connected through doors to each other and to the Fountain Hall.
The entrance to the Privy Chamber underwent various modifications under Sultan Ahmet III (1703-1730). The Kelime-i Tevhid (The Word of Unity: Islamic declaration of faith in the oneness of God) dated 1725, written in Celî Sülüs characters (a style of Arabic script with large letters used in writing inscriptions) was the work of Sultan Ahmet III who was a skilled calligrapher.  On both sides of the door we see two more inscriptions in monogram form. On the right side takes place the phrase, “Cihan Meliki Hakan-ı Emced”: “Glorious Khan Sovereign of the Universe” and the sentence on the left side reads, “Şeriat Sâliki Sultan Ahmed”: “Sultan Ahmed Devotee of the Shari’ a” (Islamic canon law).  
The first room on the right side after entering through the Fountain Hall is the Arz-hane – (Presentations Room) where the Sultan received the Arz Ağaları (the Squires in charge of submissions and/or presentations) and accepted their submissions. The second room located on the corner is the most important section of the building, namely, the Throne Room (Taht Odası) or the actual Privy Chamber (Has Oda).  Yavuz Sultan Selim designated this room for the conservation and protection of the Holy Mantle or Mantle of Felicity (Hırka-i Saadet) - believed to have been worn by the Prophet Mahomet -  he brought back from his Egyptian expedition and ordered significant changes in the organization of the Privy Chamber.  Sultans, who were staying here until the second half of the 16th Century, continued traditionally until the end of the empire, to sit in this room before the ceremony of accession to the throne. They paid visit to the “Mantle of Felicity” each year, on the 14th and 15th day of the month of Ramadan, within the framework of an official ceremony.  The Privy Chamber was maintained and restored with great care by all successive Sultans out of respect for the sacred relics sheltered therein. Each sultan in his time attached great importance to keeping the place in prime condition.  The Privy Chamber has the most originally designed tiles among Sultans’ pavilions, dating from the end of the 16th Century and which fortunately survived up until our present-day.
