İstanbul, the heart of Turkey, is one of the oldest metropoles of the world with its 2700 years history. The city has been home to many prior civilizations and called as "Byzantium" and "Constantinople" in the old times. İstanbul, capital to the three major empires of their times; Roman, Byzantium and Ottoman empires, is like an open air museum where ruins of all three empires are still exhibited.
İstanbul is located on seven hills geographically and known as the "city with seven hills". The Bosphorus right in the middle of the city divides İstanbul into two, Europe on the western side and Asia on the eastern. This makes İstanbul the only city in the world spread on two continents…
The rich history of İstanbul that accumulated in centuries becomes visible especially around the "Golden Horn" in the old city district. Prominent works of architecture like Topkapı Palace, Sultanahmet Mosque and Hagia Sophia are located in that region.
