Underground Naples

This guide to Underground Naples takes you forty meters beneath Piazza San Gaetano, into tunnels first cut by Greek settlers in the third century BC and later turned into Roman aqueduct channels carrying water from springs seventy kilometers away. You'll hear about the pozzari, the men who climbed down on ropes for two thousand years to keep the water clean, and how the same tunnels became an air-raid shelter for terrified families during World War Two. Some of the Roman cisterns down here are still full of water today.
