Seine-et-Marne

Seine-et-Marne is a department in the Île-de-France region in Northern France. Named after the rivers Seine and Marne, it is the region's largest department with an area of 5,915 square kilometres (2,284 square miles); it roughly covers its eastern half. In 2019, it had a population of 1,421,197. Its prefecture is Melun, although both Meaux and Chelles have larger populations. History Seine-et-Marne is one of the original 83 departments created on 4 March 1790 during the French Revolution in application of the law of 22 December 1789. It had previously belonged to the former province of Île-de-France. It is the only original departement in the Île-de-France that has remained unchanged, as both Seine and Seine-et-Oise were abolished and reorganised in 1968. Geography Situation
