We journeyed via the icy, crystal clear waters of subterranean aqueducts that feed the Trevi fountain and 2000 year old sewers which still function beneath the Roman Forum today, to decadent, labyrinthine catacombs. Our laser scans map these hidden treasures, revealing for the first time the complex network of tunnels, chambers and passageways without which Rome could not have survived as a city of 1M people.
