A crew watching over an Audomarois marsh

They are captain, archaeologist, machinist, biologist or even “rumorologist”. Consequently, they are recognized as true experts in their fields and they work hard to better understand and preserve this unique and exceptional natural space that is the Audomarois marsh...

From the escape of a Royal Air Force pilot to the discovery of the typical market gardeners' tools, including the control of water and the shaping of this landscape by the hand of man for more than 13 centuries, the The Sous-Marais exhibition is also an opportunity for young and old to learn more about the means of safeguarding this exceptional heritage on several levels.

Classified as a Biosphere Reserve by UNESCO, the marsh is the center of very particular attention from an environmental point of view with the aim of preserving its riches and its ecological particularities.

Extend your discovery with some of the 29 species of fish found in the marsh. Our aquariums welcome some of their representatives.
