Naples is a city of extraordinary beauty and art, but few people know about its hidden history. Forty meters underneath the ancient city of Naples lies a vast geothermal zone made of tuff (a volcanic sandstone). Extensive underwater caves that were used as cisterns led to further development of tunnels and underground structures. In fact, these caves and caverns are the soul of Naples, and what has made the city what it is today.
