An artist committed to environmental causes, Julian Charrière (Switzerland, 1987) is taking over the dome of Fort Sainte-Agathe for the second year. Inspired by the story of Agatha of Catania, who gives her name to the fort and who is invoked for protection against, among other things, earthquakes, volcanic eruptions, and fires, Julian Charrière invites us on a meditative journey into the bowels of the Earth.
