Ten thousand days, 93,000 hours, 33 years of work, that’s the time it took Ferdinand Cheval to build his Ideal Palace in Hauterives in the Drôme. 110 years after its construction, the famous French artist, Jean-Michel Othoniel, invests this high place of art brut and naive art, with contemporary works made of glass and light. His project is called “The Dream of Water”.
