This is the point where the Bosphorus meets the Black Sea. I took this photo on May 12, 2020, while cycling during the lockdown. To the left is north, leading to the Black Sea, and the right is south, where the Bosphorus flows.eft is north, where the Black Sea is, and the right is south, where the Bosphorus flows.

The point where the Bosphorus meets the Black Sea is an area of immense geographical and cultural significance, marking the northernmost boundary of the Istanbul Strait. Here, the narrow passage of the Bosphorus opens up into the vast expanse of the Black Sea, creating a unique convergence of waters that has shaped the history and character of Istanbul and the surrounding regions.
Geographically, this point represents the intersection of two major bodies of water, each with its own distinct ecological and hydrological characteristics. The Bosphorus, known for its strong currents and strategic significance, has served as a key maritime route for centuries. In contrast, the Black Sea, one of the world’s largest bodies of water, has its unique ecosystem and plays a crucial role in the economy and ecology of the surrounding countries. The meeting of these waters is not only a spectacular natural sight but also a point of significant environmental interaction.


Historically, the convergence of the Bosphorus and the Black Sea has been of strategic importance. It has been a gateway for naval and commercial shipping between the Mediterranean and the Black Sea regions, influencing the political and economic dynamics of the empires and nations that have controlled it. From the Byzantine and Ottoman Empires to modern Turkey, control over this point has been a coveted prize, playing a pivotal role in regional and international trade.
Today, the area is a popular spot for tourists and locals alike. It offers breathtaking views, especially at Anadolu Kavağı and Rumeli Kavağı, the last ferry stops along the European and Asian sides of the Bosphorus, respectively. These locations provide a picturesque setting to witness the grandeur of this geographical marvel. The surrounding areas are dotted with historical fortresses, seafood restaurants, and scenic pathways, making it a perfect place for a day trip from Istanbul.
