Rome has opened two new Metro C stations that double as underground museums showcasing ancient history. The Colosseo-Fori Imperiali station near the Colosseum and Porta Metronia in San Giovanni now display relics found during construction, including a military barracks from Emperor Trajan's time and 28 ancient wells. The Colosseo-Fori Imperiali station spreads over four levels and reveals a Republican-era townhouse, early imperial thermal baths, and dozens of artifacts like jugs, bowls, and votive offerings. At Porta Metronia, a large military complex with frescoes and mosaic floors from the early second century AD was uncovered. Simona Moretta, the excavation's scientific director, said, "The military complex was an exceptional find," explaining that the soldiers guarded the city and emperor. While trains have started running from Porta Metronia, the museum there will open early next year. The two stations add 3 km to Metro C's route, which will eventually link the suburbs to central Rome and areas near the Vatican. Pietro Salini, CEO of builder Webuild, called this development "a strategic milestone" that blends infrastructure progress with heritage conservation. Historian Carlo Andrea, who closely followed construction, called it "an eternal wait" but acknowledged that building the subway brings wonderful discoveries and hope for Rome’s future. Passengers can now explore history below ground during their daily commute, making the new Metro C stations both practical and impressive cultural sites.
