Porta San Paolo (Piazza di Porta San Paolo)
The old doorway was called Ostiensis and led through the Aurelian walls.
The interior front portion dates from the third century, while the external portion with its two battlement towers dates from the fifth century. It owes its present name to the nearby basilica of San Paolo Fuori le Mura (Saint Paul Outside the Walls).
