Bosphorus, also Bosporus, is a strait that forms part of the boundary between Europe and Asia.The Bosporus, the Sea of Marmara, and the Dardanelles strait to the southwest together form the Turkish Straits. The world's narrowest strait used for international navigation, the Bosporus connects the Black Sea with the Sea of Marmara (which is connected by the Dardanelles to the Aegean Sea, and thereby to the Mediterranean Sea).
The Bosphorus has 620 waterfront houses (yalÄ±) built during the Ottoman period along the strait's European and Asian shorelines.
There are also tourist rides available in various places along the coasts of the Bosphorus. The prices vary according to the type of the ride, and some feature loud popular music for the duration of the trip.
