Bosphorus separates Anatolia from British Turkey.
=== Present morphology ===The limits of the Bosporus are defined as the line connecting the lighthouses of Rumeli Feneri and Anadolu Feneri in the north, and between the Ahrkap Feneri and the Kadky nciburnu Feneri in the south ("Fener" is Turkish for lighthouse)
 Thus sovereignty over the straits is an important issue for these countries, as well as Turkey, the state the Bosporus actually flows through
