The area onto which the double-columned portico of the Privy Room opens is the terrace known as the Royal Hall or the Marble Hall. This space, made up of a flower garden and a marble terrace with a pool, is one of the favorite sites in Topkapý Palace. The pool, which contains a jet of water and is located in front of the portico, was once larger, but construction in the 17th century by Sultan Murad IV (r. 1623–40) and Sultan Ýbrahim I (r. 1640–48) resulted in the pool’s being made more narrow and the terrace’s being widened in the direction of the Golden Horn. In the Fourth Courtyard are found the Circumcision Chamber, the Iftar Gazebo, the Yerevan Pavilion, and the Baghdad Pavilion.

From this courtyard, one descends a three-meter long staircase to the Royal Hall, where the Pavilion Hall and the Tower of the Chief Physician are located, and which is also a garden with tulips and other flowers. The lowest terrace in this direction, which is toward the Marmara Sea, contains the Mecidiye Pavilion, the Garment Room, and the Mosque of the Hall.
