Basilica San Paolo is a station on the Line B of the Rome Metro. It was opened in 1955 and is located at the intersection between Viale Giustiniano Imperatore and Via Gaspare Gozzi, behind the Basilica of Saint Paul Outside the Walls in the Ostiense quarter. It is also one of three Metro stations also served by the Rome-Lido railway line.
Before reaching the station the line, in the Porta San Paolo direction, runs through a 230m gorge excavated in the 1920s from the "Roccia di San Paolo" to avoid interfering with the landscape, rather than the original plan which ran the line around the "roccia" but ran it right alongside the basilica.
