This episode is dedicated to the discovery of San Francisco, a city so prolific in architecture and art. How can you pass through San Francisco without taking an interest in the famous Golden Gate, the most photographed bridge in the world? We will then visit the De Young museum and we will go to an exhibition of works by Auguste Rodin. Another must-see place in San Francisco is the Alcatraz penitentiary. We will visit this mythical place, before ending up in a strange house called "the mystery house".
