Bosphorus

The Bosphorus connects the Black Sea and the Marmara Sea which flows to the Mediterranean and makes Istanbul the only major metropolitan center on two continents in the world. It's not as wide as the opening beneath the Golden Gate Bridge and it seems to be constantly full of huge tankers, yachts, and tiny fishing boats.

This is the view from right outside the gates of North Campus of Boğaziçi, looking across to Asia and the less populated area of Istanbul, which has a total population of over 10 million people [2000 census].
