History
The original name of the gate was Porta Ostiensis, as it was located at the beginning of via Ostiense, the road that connected Rome and Ostia. Via Ostiense was an important arterial road, as evidenced by the fact that upon entering the gate of the same name, the road split, with one direction leading to the famous Emporium, the great market of Rome.
