City

Istanbul

iss-tan-BOOL (English); Turkish [isˈtanbuɫ], colloquial [ɯsˈtambuɫ]
Also Known As Constantinople (historic name, in common use until the 1930s)
Western Asia

Istanbul straddles Europe and Asia across the Bosphorus Strait, the narrow waterway that separates the two continents and connects the Black Sea to the Sea of Marmara and, beyond it, the Mediterranean. Its site controls the shortest sea route between the Black Sea basin and the Mediterranean, making it a chokepoint for maritime trade between the two for as long as ships have made the crossing, and its natural harbor, the Golden Horn, is one of the finest deep-water anchorages on either strait shore.
