The Bosporus Strait is a narrow waterway located in Turkey, connecting the Black Sea to the Sea of Marmara. It serves as a natural boundary between the continents of Europe and Asia. The strait is approximately 31 kilometers long and varies in width, with its narrowest point being about 700 meters. This important maritime route is vital for international shipping and trade, as it allows vessels to transit between the two seas. The strait is also home to several historical sites, including the Maiden's Tower and the Rumeli Fortress, which reflect the rich cultural heritage of the region.
