Discover Seine-Et-Marne : Geography
From its highest point at 215 m altitude on the Saint-Georges de Verdelot butte to its lowest point at Seine-Port at 35 m altitude, Seine-et-Marne offers contrasting landscapes, with valleys to the north of the Marne, plateaus in the Brie and Gâtinais regions and vast wooded areas. This diversity is complemented by numerous waterways, including the Marne and the Seine, which have shaped the region's identity over time. The same is true of its geology. Situated at the heart of the Paris Basin, with its limestone, hard, sandy and clay zones, Seine-et-Marne is home to large deposits of raw materials (sandstone, sand, gravel, clay, gypsum, chalk, etc.) that have long been exploited. Seine-et-Marne is also France's most enclosed département, sharing its borders with Val-d'Oise, Seine-Saint-Denis, Val-de-Marne and Essonne to the west, Loiret and Yonne to the south, Aube and Marne to the east, and Aisne and Oise to the north.
