Thie third longest river in France, the Seine originates in Dijon before flowing through Paris and emptying into the English Channel at the port city of Le Havre. Paris is roughly bisected by the Seine; the resulting parts are referred to as the Rive Gauche and Rive Droite. It is both economically and strategically important, as it allows one to access Paris and much of northern France from the sea.

Much of Paris' romantic charm is attributable to the Seine and various landmarks on her banks, including Notre Dame, Pont Neuf, The Louvre, the Eiffel Tower, the Musee D'Orsay, and the Fontaine St. Michel.
