In the 19th and 20th centuries, La Grève des Courses was a festive place where horse races and aviation meetings took place. However, it later became a wild dump where waste was thrown directly onto the sand, polluting the bay. Thanks to the efforts of environmental associations, it was transformed into a nature reserve.

The site is exceptional because it is located in the Nature Reserve which is home to a very varied fauna and flora. It can accommodate up to 40,000 migratory birds in winter. The site is also remarkable because it is located in the heart of the bay of Saint-Brieuc, the fifth bay in the world for the amplitude of its tides. The sea can recede more than 7 km! It is this natural heritage that the Maison de la Baie, classified as Maison Nature, lets you discover through its museum, its temporary exhibitions, its educational activities, its walks and its nature outings. Actions that show the richness of biodiversity, raise awareness of environmental protection and develop eco-citizen behavior. https://www.saintbrieuc-armor-agglo.bzh/sortir-et-decouvert/proteger-notre-environnement/preservation-de-la-baie/la-maison-de-la-baie
