From the Treasury Halls, there are stairs leading down to the Fourth Courtyard. This courtyard was exclusively reserved for the Sultan's own pleasure and nobody else was allowed without the permission of the Sultan. Upon the entrance, there's a little mosque on the right, this is just a little room to pray during the pray times.After a couple of stairs, comes the wonderful view of the Strait Bosphorus. The bridge is connecting Asia and Europe and the opposite side is the Asian Side. In a sunny day, the water is light blue and one can see the islands lying on the right hand side. They are called as "The Princes' Islands" which is another municipality of Istanbul. The Bosphorus is a great spot, one should take a boat trip along the Bosphorus. There are stairs from the entrance of the courtyard to a 101-year old restaurant "Konyali" which will contribute to one's enjoying of Istanbul.

A  passageway leads to a corner which is a great spot for taking a lovely Bosphorus picture. As one turns left from the corner, there are lovely chestnut trees in the garden and the building on the left is called "the Mecidiye Kiosk". It is the last building added into Palace area before the Sultan left to move into "Dolmabahce Palace". The building dates back to 1840 and was erected by Sultan Abdul Mecid I. It's now being used as the management of "Restaurant Konyali".

As one takes the way to the right, after taking 4-5 steps, there is a lovely passageway through a refreshing garden. After completing the steps, there is little fountain and pool on the left side. This is another courtyard which the floor is marble and there is little canopy standing to observe the gorgeous view of the Golden Horn. On the left, stands the Suleiman's Mosque with all its magnificence. There are ferries and boats operating from Golden Horn to the Bosphorus and the bridges are always busy. On the right hand side, lies the New Part of Istanbul with all its big hotels and modern structures. The gold decorated little canopy is called "Aylık" which the Sultan observed the full moon.

The building on the right of the canopy is called "the Baghdad Pavillion" which was constructed to celebrate the conquest of Baghdad. The building is decorated with lovely Iznik tiles and inside the building is quite ornate. The fireplace and the hand paintings on the dome are worth seeing. There are beautiful examples of mother-of pearl inlaid into beautiful wardrobes. There is a brazier in the center of the room which served as a means of making Turkish coffee or to warm up the room in cooler days. 

An interesting room in the same courtyard is the "Sunnet Odasi", "the Circumcision Chamber". This room is surrounded with splendid tiles and dates back to 16th C. According to the Islamic principles, all the male children should be circumsized after completion of 6-7 years of age. The child is not circumsized right after it's born because the logic is the child should grasp why the ceremony takes place. There are feasts given to people, music bands play and people eat and dance with joy... The boy gets nice gifts to forget about the pain of the operation and remembers the feast of his first step to maturity.

The last pavillion on the Fourth Courtyard is called "Revan Kosku", Revan Pavillion. It was built by Murat IV in 1636 to commemorate the capture of Revan in Iran. It is a small replica of the Baghdad Pavilion. The central brazier was a gift of the French King Louis XV, to Mahmut I, made by Duplesisa, a famous worker in bronze of the time. This room was also known as the Turban Room, as it was here that the sultan’s turbans were kept.
