History
Digging began about 5,000 years ago, at the end of prehistory, and Greeks quarried tuff here to fortify Neapolis. Most houses above were built with tuff dug on the spot. From 1968, sewer breaks and aqueduct leaks made the ground unstable. Brothers Michele and Salvatore Quaranta founded the Free Association Underground Hikers.
