France has reopened the Seine River for public swimming for the first time since 1923

What is it?

A significant historic river in Europe and an essential inland navigation route.

Situated in: Northern France, crossing significant areas such as Île-de-France and Normandy.

Origin and Pathway:

Originates at Mont Tasselot in the Côte d’Or area of Burgundy at a height of 1,545 feet.

Length: Measures 780 km (485 miles).

Mouth: Discharges into the English Channel at Le Havre.

Geography and Movement:

Courses northwest through Paris, merging with various tributaries—Aube, Yonne, Marne, and Oise.

Exhibits slow flow and limited navigability because of a slight elevation gradient (merely 80 feet above sea level in Paris).

Experiences tidal bore (mascaret) at the estuary, though this has diminished because of dredging.

Economic Importance:

Key trade waterway, particularly south of Paris, connecting to Le Havre and Rouen.

Links to the Rhine, Belgian, Loire, and Saône-Rhône river networks.

Recent improvements have allowed the river to become swimmable again, enhancing both tourism and ecological restoration.
