The palace is a complex surrounded by 5 km of walls and occupies an area of 700,000 sq. m at the tip of the historical peninsula. 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 Topkapi Palace. Topkapi is a classical example of Turkish palace architecture. It consists of tree- shaded courtyards, each serving a different purpose and opening onto one another with monumental gates.
