Marennes-Oléron oysters are the only French oysters to benefit from a Protected Geographical Indication (PGI).
The distinctive green color of 'Fine de Claire Verte' oysters comes from the Navicula ostrearia algae found in the local claires.
The site is located on the Route de la Huître, which highlights the basin's history of salt production transitioning into oyster farming.
Oysters are placed in claires (shallow clay basins) for several weeks to improve their texture and flavor, a process unique to this region.
The estuary of the Seudre is one of the most significant areas for oyster refining in Europe.
Cité de l'Huître is an interactive thematic park dedicated to the history and cultivation of Marennes-Oléron oysters. Located along the Seudre estuary, the site features outdoor pathways through traditional marshlands and reclaimed salt pans. Visitors can observe the refining process known as 'affinage' in the 'claires,' where oysters acquire their characteristic flavor. The museum offers exhibits on the maritime heritage of the region, including local fishing techniques and the ecology of the basin. Educational installations demonstrate the biological lifecycle of the oyster from spat to harvest. The facility serves as a focal point for understanding the Marennes-Oléron Protected Geographical Indication status. It is situated within a protected natural site characterized by its flat landscape and proximity to salt marshes. The architecture integrates with the surrounding coastal environment to facilitate an immersive experience.
The elevated viewing points along the wooden walkways overlooking the colorful huts and the Seudre estuary.
Bring comfortable walking shoes to navigate the earthen paths between the marshes.
Check the tide schedule, as the appearance of the marshlands and water levels change drastically throughout the day.
Plan to participate in a guided tasting session to learn how to identify the nuances of different oyster grades.
Do not attempt to collect oysters or equipment from the working oyster beds as these are private property.
The site is typically closed during the winter months and follows a seasonal schedule; check ahead for spring opening dates.
Casual, outdoor-appropriate clothing; avoid disturbing the wildlife or vegetation in the marsh areas.
