Marais de la Seudre

The Marais de la Seudre is a protected wetland in Charente-Maritime stretching across approximately 12,000 hectares between Marennes and Saujon. The landscape consists of salt meadows, tidal flats, and coastal lagoons interconnected by a network of channels.

The area was organized as a salt production zone during Roman times, contributing to the economic prosperity of the Saintonge region. By the 17th century, the focus shifted from salt harvesting to oyster farming, fundamentally transforming the landscape.

The marshland today is shaped by oyster farming, which defines the landscape of basins where Marennes-Oléron oysters develop their distinctive flavor. Visitors can observe how these cultivation basins structure daily life in the area.

The area offers walking paths throughout the year for exploring the diverse ecosystems and observing local and migratory bird species. Sturdy footwear and binoculars are recommended to fully enjoy the abundance of birdlife in the region.

Within the marsh stands the Moulin des Loges, a medieval structure with a hydraulic mechanism that operates according to tidal rhythms. This restored facility demonstrates how earlier inhabitants harnessed natural forces for practical purposes.
