The Seine River is a 485 mi (780 km) long river in France that flows into the English Channel between Le Havre and Honfleur.

Known as the second-longest river in France, the Seine River passes through important cities in the country like Paris, Rouen, and Troyes. The drainage basin of the Seine River has a surface of 48,871 mi (78,650 km).

The Loire is the longest river in France, and the Seine River comes second. The river begins 18 mi (29 km) northwest of the city of Dijon and flows through Paris in a northwesterly direction.

The Seine River then flows into the English Channel at Le Havre.

The 485 mi (780 km) river is one of the great historic rivers of Europe, and the drainage network of this river carries most of the inland waterway traffic of France.

Île-de-France is where the fertile center of the Seine River basin lies, and this made the place the cradle of the French monarchy. This also made it the center point of expansion of the nation-state, and it is still in the same heartland.

Impressionism in France has been hugely popular and influential, and the River Seine has been the subject of many famous impressionist paintings all over the world. Some of these paintings are Monet’s Bathers at La Grenouillère and Renoir’s Seine River at Asnieres.

Half of the water in Paris is still supplied by the Seine River, so you can get to know how important the River Seine is for the sustainability of the region. Every summer in Paris, the roads on the bank of the Seine River are closed, and the roadways are covered in palm and sand trees.

People transform the area into Paris Beaches or Paris Plages.

At the Seine River of Rouen, the ashes of Joan of Arc were scattered.

The Seine is not just a water body that flows through Paris. The Seine is also home to many bridges and is famous throughout the world. Both for economic and fun-filled purposes, the river is very important.

Did you know that the Vikings pillaged the Upper Seine, destroyed much of the city of Rouen, and used the river to attack Paris? During the ninth century, they laid siege to the city of Paris but could not succeed.

This was a testament to the resilience of the French rulers and how they stopped every attack from the city of Paris.

Fun Facts About The Seine River

The Seine River has been an important part of French history and culture, and it still proves to be a force in present-day Paris and France.

  • Paris is well known for its drainage system, so it is hard to fathom people in Paris, or Parisians, moving through the city using boats and walkways. However, the Seine rose to a height of 28.2 ft (nine m) during the 1910 flood, almost to the height of Pont d'Austerlitz. The city of Paris went into lockdown.
  • The Parisian landmark of the Zouave statue on the Pont d'Alma is used to determine the water level. The water of the Seine came to the shoulder of the statue during the flood. Several old buildings in the Paris region today have the markings to show how high the water actually rose during the flood.
  • The people of Paris swam in the river during heat waves. There were several swimming competitions like The Crossing of Paris, and some people even swam naked in the river before 1923. There were even boats installed to take hot baths.
  • The Seine now serves as a commercial waterway in the Paris region and the rest of France. A village named Source-Seine is the source of the river. The village is located in a remote location at the height of 1,545 ft (470 m) above sea level. The river then follows a northwesterly pattern through Paris and is connected to the River Rhine by the River Marne. The Seine Estuary is the mouth of the river, and it is located between Honfleur and Le Havre on the English Channel.
  • The River Seine was also declared a UNESCO World Heritage Site in 1991. So, it is not just Parisians that believe in the serenity of the river and all its tributaries.
  • The river freezes when the temperature drops below 18 F (-7.7 C).
  • This long river in northern France rises at Source-Seine, which is around 19 mi (31 km) northwest of Dijon in northeastern France in the Langres plateau.
  • Pont Neuf, Pont Des Arts, and Pont Louis-Philippe are the main bridges in the city of Paris, and there are many other bridges outside of the city.
  • Many of the world's greatest artists have taken inspiration from the river for their paintings. These artists include Raoul Dufy, Henri Matisse, Claude Monet, and Alfred Sisley, among many more.
  • Paris sees the river flowing through high embankments. As the river has a meandering course, it is often confusing at first to determine the sides of the banks. If you stand by the edge looking down at the river, the bank towards your left is the Left Bank, while the bank towards the right is the Right Bank.
