Istanbul is a megacity, as well as the cultural and financial centre of Turkey. Istanbul is located in the northwest of the country on the Bosphorus Strait and encompasses the natural harbor known as the Golden Horn. It extends on both the European (Thrace) and on the Asian (Anatolia) of the Bosphorus, and is thereby the only metropolis in the world that is situated on two continents.
