Istanbul is the only city that spreads on two continents – Europe and Asia. It is probably one of the main hidden reason for such a incredibly deep and colorful culture and such a open and embracing mentality of its citizens.
Istanbul is the largest city in Europe and 4th largest city in the world.
After Constantine the Great made the city The New Eastern Capital of the Roman Empire in 330 CE, the city became widely known as Constantinople, and remained this name until the establishment of the Turkish Republic in 1930.
Hagia Sophia – “The Holy Wisdom” is the former Greek Orthodox Christian patriarchal cathedral, later an Ottoman imperial mosque and now a museum (Ayasofya Müzesi) in Istanbul.
