The Seine

The Seine is a river with a total length of 774.76 km, from its source to the sea.
Its name comes from the Latin word “Sequana.”
The Seine flows through Troyes, Paris, Rouen, and Le Havre.

Its source is located at Source Seine, at an elevation of 446 m, in the Côte-d'Or department.

The Seine flows into the English Channel between Le Havre and Honfleur.

The Seine flows through Paris for a little over twelve kilometers—almost thirteen—between the Amont Bridge and the Aval Bridge, both of which are located under the périphérique (the traffic-light-free ring road surrounding Paris).

The Seine flows through Paris, and most of Paris's historic landmarks (the Eiffel Tower, Notre Dame, the Louvre Museum, etc.) can be seen along its banks.

Its depth ranges from three to six meters, and its width ranges from thirty to 200 meters in some places.

Thirty-seven bridges span the Seine in Paris, some of which are for pedestrians only (Pont des Arts, Pont Mirabeau, Passerelle Debilly, Leopold Sédar Senghor, Simone de Beauvoir, Pont de la Concorde, etc.).

Other bridges are used exclusively by trains (Austerlitz Viaduct, Rouelle Bridge)

In Paris, there are three islands, one of which is artificial:

• Île de la Cité (where Notre Dame de Paris is located)
• Saint Louis Island
• Swan Island (artificial)

Nine subway lines—all underground—cross the Seine beneath its riverbed; three other lines run above ground.

In 1991, the banks of the Seine were designated a UNESCO World Heritage Site.
