The ecomuseum of the bay of Mont-Saint-Michel is a museum in La Manche, located in Vains. It opened in 2001 under the name Maison de la Baie. It is dedicated to the formation and life of the bay of Mont-Saint-Michel. Housed in an old farmhouse, a traditional farm of the bay, on the edge of the coast, it is an interpretation center on the formation and evolution of the bay, its fauna, its flora and the activities, past and present, of the men in the bay of Mont-Saint-Michel. The Maison de la Baie de Vains changed its name in 2011, a year after the closure of that of Courtils, to allow better identification of what this place is and what it offers. The ecomuseum is a property of the Conservatoire du Littoral developed, managed and run by the Manche Departmental Council as part of the departmental network of Manche sites and museums.

The Château d'Avranches was built around 950 by Onfroi Le Dane, on the remains of the old Roman walls. Located on a rock, the fortress could monitor the bay of Mont-Saint-Michel and the various invaders made no mistake and occupied it; Celts with the Abrincates, Romans, Saxons, then Franks. A succession of enclosures and ditches were added to it. The Roman keep unfortunately disappeared in the last century. The top of the curtain forms a platform at the same level as the terrace. A diagram, made by Canon Pigeon, shows how keep and curtain wall were connected. This is also verifiable in a document kept in the Calvados Archives. Another detail should be noted, it is impossible to access the terrace from inside the building. Passages were obstructed after a collapse of the upper level of the building, at an undetermined time. Today, at the top of a crenellated curtain wall, one discovers a panorama over the bay and the valley of the Sée, in the heart of the various Avranchinese districts.
