Marais-Vernier Village and Thatched Cottages

Highlight • Settlement

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.

Marais Vernier Viewpoint

Highlight • Viewpoint

The Marais-Vernier is a natural region of the Eure department in the Normandy region. Coming from a former meander of the Seine, this region constitutes a semi-circular depression which groups together wet meadows, marshes, reed beds, canals, ponds, ponds, peat bogs, courtils and groves.
The Marais-Vernier is rich in a remarkable natural heritage with its flora (pollard trees, holly hedges, turficole species, etc.), its fauna made up of many protected species (storks, hawks, harriers, owls, etc.) and its hydraulic network (canals, ponds, ponds, etc.). In addition, it is home to a peat bog with an area of nearly 1,800 hectares, which constitutes, in peat volume, the largest peat bog in France.
