The garden of the museum is not born by chance. It wants to give a suggestion. The walk that crosses recalls the path of a river and, on its "banks", there are some plants that existed already in Pleistocene. Almost all are still part of Mediterranean and temperate environments that characterize the Italian peninsula.
