Rome extends Metro Line C to the Colosseum

On 16 December 2025, the new section (construction lot T3, 3.2 km) of Rome Metro Line C from San Giovanni to Colosseo/Fori Imperiali opened, adding the two new stations Porta Metronia and Colosseo/Fori Imperiali. The Colosseo station provides the first interchange between Line C and Line B, while the connection to Line A remains at San Giovanni. Line C now totals 24 stations over 21.2 km, is fully automated (driverless), and runs from the eastern suburb of Monte Compatri-Pantano into the historic centre.
