Seine
 The Seine (French: La Seine pronounced: [la sɛːn]) is a 776 km long river and an important commercial waterway within the Paris Basin in the north of France. It rises at Source-Seine 30 kilometers northwest of Dijon in northeastern France in the Langres plateau flowing through Paris and into the English Channel at Le Havre (and Honfleur on the left bank). It is navigable by ocean-going vessels as far as Rouen 120 km (75 mi) from the sea.
