About Istanbul
Istanbul (Turkish: İstanbul) is a very large city of fantastic history, culture and beauty. Called Byzantium in ancient times, the city's name was changed to Constantinople in 324 CE when it was rebuilt by the first Christian Roman Emperor, Constantine. The name "Istanbul", perhaps surprisingly, comes from Greek and could be translated as a corruption of "to the city".
