Istanbul (IV): Alias Constantinople

It was built in 658 BC on the eastern tip of the Balkan Peninsula and on the west bank of the southern mouth of the Bosphorus. In 324 AD, Constantine the Great of the Roman Empire moved his capital from Rome to Constantinople. After the Turks became the capital of the Ottoman Empire in 1453, it was originally called Istanbul, but Western countries still used to call it Constantinople. The famous Bosphorus Bridge, also known as the Eurasian Bridge, was built at the narrowest point of the Bosphorus Strait and officially opened to traffic in October 1973, and is the first cross-sea bridge to cross the Bosphorus And connect the two continents of Asia and Europe. Istanbul, the capital of the three ancient empires – the Roman Empire, the Byzantine Empire and the Ottoman Empire – has preserved a glorious historical heritage and is a source of pride for the Turkish people. Istanbul is the center of gravity of Turkey's economy and culture.
