The Basin and Borders

The Black Sea is bordered by six nations, each contributing to its diverse cultural tapestry: Bulgaria, Romania, Ukraine, Russia, Georgia, and Turkey. Its unique geographical positioning links it to significant bodies of water such as the Mediterranean Sea via the Bosporus Strait and the Sea of Azov through the Kerch Strait.

Shape and Size

Covering an expansive area of around 436,000 square kilometers (168,000 square miles), the Black Sea’s elongated form stretches from the southeastern tip of Europe to the northwestern edge of Asia. With a maximum length of about 1,175 kilometers (730 miles), its width ranges from approximately 400 kilometers (250 miles) at its broadest to a mere 30 kilometers (19 miles) at its narrowest point.

Coastal Features

The Black Sea’s coastline is a blend of sandy beaches and rugged cliffs, giving rise to numerous coastal cities and towns that contribute to the region’s rich cultural heritage.
