Explore the Marne & Properties in the Area

Marne is a beautiful department situated in the Grand Est region of France. It derives its name from the river Marne, which flows through it, as with many other departments in the country. Marne's prefecture (capital) is Châlons-en-Champagne, formerly known as Châlons-sur-Marne. Marne (department number 51) is surrounded by the departments of Ardennes, Meuse, Haute-Marne, Aube, Seine-et-Marne, and Aisne. Geologically, Marne is divided into two parts: the Upper Cretaceous chalk plain in the east and the more wooded and hilly Eocene and Oligocene in the west. The Champagne vineyards that produce the world-renowned sparkling wine are also situated within the Marne, making it a popular destination for wine enthusiasts. The department is dotted with several rivers, including the Marne, Vesle, Ardre and Somme-Soude. Additionally, other rivers, such as the Grande and the Petite Morin, originate in the department but flow mainly in other departments. Conversely, the Aube joins the Seine in the Marne department, adding to its natural beauty.
