Seine is a former department of France, which encompassed Paris and its immediate suburbs. It was the only enclaved department of France, being surrounded entirely by the former Seine-et-Oise department. Its prefecture was Paris and its INSEE number was 75. The Seine department was disbanded in 1968 and its territory divided among four new departments: Paris, Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne.[1]
