Sound walk

Although it’s due to be completed in 2028, the future Cité des Imaginaires has commissioned a “sound walk” this summer in the hearth of the Jardin Extraordinaire.

Through sounds and voices, visitors can float in a Nantes suspended between past and future, true stories and fiction, rising above the garden before diving back with delight. This original work was created by Floriane Pochon and Alain Damasio, a major figure in science fiction.
