Le Marais Vernier, to whom the village of Marais-Vernier owes its name, was a vast swamp in a loop of the Seine. In 1599, Henri IV decided to dry the swamp and hired Dutch dike farmers for this task. The dike was straightened by dikes. The former river loop became a fertile land, interspersed with wet meadows, which are still drained by canals.
The village of Marais-Vernier is an elongated village characterized by thatched houses, the typical Chaumières, on whose ridges irises grow, and apple orchards. To the west rises steeply "la côte", the former bank edge of the Seine.
