Train Tunnel Excavation Reveals Artifacts

"Planners aim to send the new C line under the city centre at a depth of 30 metres, well beneath the archaeological treasures that litter Rome. Stations will also be built deep underground, but even the simple task of digging entrances and exits is proving a headache and could mean the scrapping of the Largo Torre Argentina stop, which serves crowded tourist sights such as the Pantheon."

"The C line's builders have offered archaeologists a rare glimpse at Rome's imperial past and are obliged by law to slalom around valuable finds."
