Origin and history
The Maison de la Baie du Marais poitevin, classified museum of France, is a space dedicated to the discovery of local heritage, located in Esnandes in Charente-Maritime. Located at the gates of the Poitevin Marais and on the edge of the nature reserve of the Bay of Aiguillon, it combines exhibitions on mussel farming, tourist information office and valorisation of Romanesque architecture, notably through the Church of Saint Martin.
Created in the 1990s to promote the Bay environment and mussel breeding techniques, the Bay House has diversified its activities. Today it proposes a museum trail on mussel farming, an activity introduced in France in the 13th century according to legend, with a focus on the technique of culhot appeared in 1235. Esnandes is thus presented as the cradle of this practice, essential to the local economy.
The fortified church of Saint Martin, classified as a historical monument since 1840, is a 12th century Romanesque building rebuilt in the 14th century to protect itself from English incursions. Its defensive elements (reparts, mâchicoulis, round path) make it a rare example of military religious architecture. Guided tours allow you to admire its view of the bay and understand its historic role in coastal defence.
The museum is part of a territory marked by the Poitevin Marais, France's second wetland, and the Bay of Aiguillon, a major birdwatching site. Nearby, Pointe Saint-Clément offers a natural path to observe culhots and migratory birds, illustrating the link between cultural heritage and biodiversity.
The Maison de la Baie also plays a practical role: it informs visitors about local activities, offers accessible rates (museum at €3.50, guided tours at €7), and is accessible to people with reduced mobility. Its address, Church Parvis, 17137 Esnandes, makes it an ideal starting point for exploring the region.
