Overview

  • Rome inaugurated the Colosseo–Fori Imperiali and Porta Metronia stops on Line C, extending service into the historic center.
  • At Colosseo–Fori Imperiali, a four-level station 32 meters deep presents about 350 recovered objects and visible bathhouse remains accessible with a standard ticket.
  • Porta Metronia reveals a nearly 80-meter second‑century barracks and a frescoed residence, with remains viewable in-station and a dedicated museum space planned.
  • The construction consortium reports more than 500,000 artifacts recovered and employed ground freezing, sacrificial diaphragms, and a descending archaeology method with intermediate slabs.
  • The project envisions 31 stations over 29 kilometers at a total cost near €7 billion with completion expected by 2035, as work moves next toward Piazza Venezia.
