The Seine-Maritime department, located in the Normandy region, in the northwest of France, is a department rich in history and cultural heritage.
Bordered by 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 Seine-Maritime department was created in 1790, during the French Revolution. Until 1955, it was known as Seine-Inférieure.
The main cities in 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 true lands of convergence between Norman, English, and French influences, Seine-Maritime has been the stage for many significant events.
