The department of Seine-Maritime, located in the Normandy region, in the northwest of France, is a department rich in history and cultural heritage.
Bordering the English Channel to the north and the Seine estuary to the west, the department is bordered by the Somme, the Oise, the Calvados and the Eure.
The department of Seine-Maritime was created in 1790, during the French Revolution. Until 1955, it was known as Seine-Inférieure.
The main cities of the department are Rouen (prefecture), Le Havre, and Dieppe. Other notable cities include Fécamp, Le Petit-Quevilly, Saint-Etienne-du-Rouvray, Elbeuf, and Montivilliers, all steeped in history.
As the true land of convergence between Norman, English, and French influences, Seine-Maritime has been the stage for many significant events.
