Tunnels of Claudius

The Claudius Tunnels consist of one main underground channel, six service tunnels, and thirty-two vertical shafts through Mount Salviano.

Emperor Claudius commissioned this water drainage system between 41 and 52 CE, employing 30,000 workers to construct the extensive tunneling network.

The tunnels demonstrate Roman engineering capabilities, as they remained the longest underground passage until the completion of Frejus rail tunnel in 1871.

Guided tours operate every Saturday from 15:00 to 19:00, requiring advance reservations and appropriate clothing including closed non-slip footwear.

The hydraulic system directed water from Lake Fucino to the Liri River through a 5.6-kilometer tunnel, enabling the drainage of Italy's third-largest lake.
