The Eclosarium on the island of Houat is a multifaceted cultural place where everyone can concoct their own program: dive into the secret life of the oceans, learn about the history of the island, admire a photo exhibition or even enjoy the shop, which features creations by local artists and offers products from Marineaniel Jouvance Cosmetics.

On the Museum side, the Eclosarium transports us to the world of marine life which reveals the fragility and importance of the microscopic marine world.

From the first archaeological traces to contemporary times, we also learn the history of the island of Houat and the life of its inhabitants, entirely devoted to the sea.
The Eclosarium is also the Marine Biotechnology Research and Culture Center of the Daniel Jouvance cosmetics brand. Treatments to discover without delay in store!
