Bosphorus Strait! The intersection between the two parts of Europe and Asia fascinated the great empires of the past centuries ago, and today it is a meeting place for artists and tasteful tourists in Istanbul. Apart from the sea traffic, this narrow and winding waterway of Northwest Turkey winds through the heart of Istanbul and divides the city into two continents, Europe and Asia. The Bosphorus is the only natural strait that connects two continents and separates the Sea of Marmara and the Dardanelles Strait. The stunning beauty and strategic location of this waterway made it the focal point of empires, trade and culture throughout history. Today, the shores of the Bosphorus combined with magnificent palaces, ancient fortresses and fishing villages have created a unique attraction in the city of Istanbul. Here we get to know the history, geographical location and finally the sights of this beautiful waterway.
The historical significance of the Bosphorus Strait
The history of the Bosphorus Strait is intrinsically linked with the city of Istanbul. Known in ancient times as Constantinople, the city was located at the crossroads of Europe and Asia, making it a favorite destination for the Romans, Byzantines and Ottomans. This strait played an important role in these empires and acted as a natural barrier against enemy attack and the gate of the Black Sea and a symbol of power.
The first recorded name of the Bosphorus dates back to the ancient Greeks in the 7th century BC. They established colonies on the coast of Europe. Hence, the name of this strait is taken from the Greek myth of Io, who was turned into a cow by Zeus and forced to swim in the waters. This water is the famous Bosphorus today.
During the Ottoman rule, the Bosphorus Strait became a vital transportation and trade center, connecting the Black Sea to the Mediterranean Sea. In addition, Ottoman palaces, mansions, and other fortifications were all built around the gorge. This strait attracted the attention of merchants from all over the world who came to Istanbul to trade spices, silk and other luxury goods.
Today, the Bosphorus still maintains its importance and strategic location, but it is also known as one of the most stylish, beautiful and popular tourist attractions in Istanbul.
Where is the Bosphorus Strait? Geographical location
The Bosphorus Strait has a unique combination of natural beauty and geological features. The strait is 32 km (20 mi) long between the Sea of Marmara and the Black Sea and varies from a minimum width of 700 meters (2,300 ft) to a maximum width of 3.5 km (2.2 mi).
The Bosphorus was created millions of years ago by the displacement of the earth’s plates, this narrow passage between two continents. This geological event also resulted in the rapid flow of the strait current in the opposite direction at different depths, making navigation challenging for commercial and naval vessels. These currents are mostly influenced by the unique hydrological conditions of the Black Sea and the Sea of Marmara.

Bosphorus attractions
Undoubtedly, Istanbul owes more than half of its beauty to the Bosphorus. The strait that separates the two parts of Asia and Europe and in each of its parts there are many buildings to see and interesting things to do. In the following, we will learn about the attractions of the Bosphorus Strait:
Bosphorus bridges
- Fatih Sultan Mehmet Bridge, which was built in 1988, is named after the Ottoman Sultan Mehmed II, who conquered Constantinople (Istanbul) in 1453.
- The 1510-meter Bosphorus Bridge, which is also called the 15th of July Martyrs Bridge, was built in 1973 and is the first bridge that was placed on the Bosphorus Strait.

The famous Eurasia Tunnel
The 5.4 km Eurasia Tunnel between the European and Asian coasts of Istanbul under the Bosphorus consists of two separate tubes for traffic and accommodates 100,000 vehicles per day. The tunnel was opened to the public in December 2016 and is the first undersea tunnel to connect two continents.
The construction of the Eurasia Tunnel, which will reduce traffic and motor vehicle congestion on Istanbul’s bridges, still requires digging more tunnels under the seabed, as well as access roads and other infrastructure. The project was funded through a public-private partnership with the Turkish government and a private consortium. The construction of the first tunnel was so successful that another tunnel may be built on top of it. In the Istanbul tour, you can visit the famous Eurasia Tunnel.

The northern entrance is where the strait meets the Black Sea.
