The Story of the Maison de l'Océan

The façade of the Maison de l'Océan, rue Saint-Jacques in Paris

Opened in 1911, the Institut océanographique was conceived as a place to study and teach the ocean sciences. For a long time it was the only establishment of its kind, renowned for equipment that kept it at the forefront of research.

Now renamed the “Maison de l'Océan” and host to countless events, our landmark address has become an environmental hub, home to many of the major players working to protect the Ocean.

A heritage devoted to the Ocean

When Prince Albert I entrusted him with the construction of his Paris institute, the architect Henri-Paul Nénot had already been commissioned to rebuild the Sorbonne. He designed a building at the cutting edge of innovation in terms of facilities: vast research laboratories, collection rooms, libraries, conference rooms and a great amphitheatre.

In keeping with the prince's wish to bring art and science together, he applied the same decorative logic he had deployed at the Sorbonne. The use of each space is illustrated by its decor: the façade is adorned with sculpted marine motifs, the secretariat plunges visitors into an underwater landscape, and the Great Amphitheatre is decorated with fishing and navigation scenes.

Since 2004, the building has been listed as a Historic Monument, a fitting recognition of the work of Nénot and of the artists who worked alongside him.
