The River Seine is a river that runs for a total of 775 kilometers (482 miles) in the north of France, which drains into the Paris Basin (a geographical lowland area), which covers the majority of the north of France. It is formed at the Source-Seine, 30 kilometers (19 mi) northwest of Dijon in northeastern France in the Langres plateau, where it travels to Paris and into the English Channel, finally reaching Le Havre (and Honfleur on the left bank).
Rouen is 120 kilometers (75 mi) from the ocean, making it navigable by ocean-going vessels all the way to the city. The majority of the river’s length, as far as Burgundy, is accessible by large barges and most tour boats, and about the entirety of the length is available for recreational boating.
The Seine is crossed by 37 bridges in Paris (some notable examples include Pont Alexandre III and Pont Neuf built in 1607) and additional bridges can be found outside of the city. Another noteworthy bridge along the racecourse is the Pont de Normandie, which is one of the longest cable-stayed bridges in the world, connecting Le Havre to Honfleur.
The Source-Seine commune is home to the River Seine, which rises to about 30 km (19 mi) north of Dijon. Since the city of Paris purchased the property in 1864, the source has been city-owned.
The main source of the water is derived from several small ditches or depressions that are nearby. Then, to highlight and contain this source, an artificial grotto has been constructed. In the grotto, you will find a statue of a nymph, a dog, and a dragon.
Other notable features of the site include the ruins of a Gallo-Roman temple buried beneath the current ground level. Additionally, small statues of the Seine dea Sequana, the goddess of the Seine, and other ex-votos located at the same location are now on display in the Dijon museum.
