Porta San Giovanni is a gate in the Aurelian Wall of Rome, Italy, named after the nearby Basilica di San Giovanni in Laterano. In preparation for the Holy Year of 1575, Pope Gregory XIII reopened ancient roads, such as the Via Tuscolana, and laid new ones, most notably the Via Merulana, linking S Maria Maggiore with the Lateran and the Via Gregoriana, leading from the Monte Cavallo to Trinità dei Monti. At S Giovanni in Laterano, Giacomo del Duca was commissioned to design a new rusticated portal leading through the Aurelian wall from the Via Latina.
