Following the conquest of the city in 1453, the young Sultan Mehmet moved the capital of the empire to Istanbul, His first palace was located in the middle of the town. The second palace, which he built in the 1470’s, was initially called the New Palace, but in recent times it came to be known as the TopkapıPalace. Topkapıis a classical example of Ottoman palace architecture. It consists of tree- shaded courtyards, each serving a different purpose and opening onto one another with monumental gates. The courtyards are surrounded by functional buildings. From the time of its construction, the palace developed constantly with alterations and additions made by each sultan.
