Although it’s due to be completed in 2028, the future Cité des Imaginaires has organized a “sound walk” this summer in the heart 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 in with delight. This original work was created by Floriane Pochon and Alain Damasio, a major figure in science fiction.
