The exhibition is located where the “cells” of the Capuchin Friars were housed about 4 centuries ago. Over 400 geological finds will introduce you to the evolution of the “Arci” volcano that gave rise to obsidian, which was already marketed in the Neolithic period (8000 years ago), minerals almost unique in the world, volcanic rocks, “precious” crystals, colorful agates and extraordinary fossils that you will see in the Fossil’s Avenue and in the Volcanic Room.
