Istanbul the transcontinental city
Bridging Two Continents
Istanbul is a transcontinental city that is divided by the Bosphorus Strait – one of the world’s busiest waterways – between the Sea of Marmara and the Black Sea.
Its commercial and historical centre is situated in Europe, while one third of its population lives in Asia. It is one of the world’s largest cities.
The Bosphorus is approximately 32km (20 miles) long, and just under 1km wide at its narrowest point, broadening out occasionally into particularly picturesque bays.
