The Gardens of the Imagination (Les Jardins de l'Imaginaire)—classified as a remarkable garden by the French Ministry of Culture—are situated in Terrasson. It was designed in 1996 by landscape architect Kathryn Gustafson to present thirteen tableaux of the myths and legends of the history of gardens. It uses simple natural elements; trees, flowers, water and stone to suggest the passage of mankind from nature to agriculture to the city. It uses a symbolic sacred wood, a rose garden, topiary art, and fountains to tell the story.
