Line C is a Rome Metro line which runs from Monte Compatri-Pantano in the eastern suburbs of Rome, in Italy, to San Giovanni near the city centre, where it meets Line A. It is the third metro line to be built in the city and the first to be fully automated. The first section, between Monte Compatri-Pantano and Parco di Centocelle, opened on 9 November 2014. The second, from Parco di Centocelle to Lodi, opened on 29 June 2015. The third, from Lodi to San Giovanni, opened on 12 May 2018. The line reuses parts of the old Rome-Pantano railway, a light railway that is the last remaining part of the Rome-Fiuggi railway. From Wikipedia
