The stretch of the walls on the right bank of the Tiber is rather fragmentary. In addition to a few portions of the original route, all that remains are three gates (Porta Portuense/Portese, Porta Aurelia/San Pancrazio and Porta Settimiana) rebuilt in modern times, a testimony to the vast almost triangular area converging on the Janiculum that Aurelian had included within the walls. It is in this area either side of the Tiber that Pope Urban VIII intervened to fortify the walls in the 17th century with the walls named after him, with the city under threat from the troops of Duke Odoacre Farnese, who were marching towards Rome after conquering Acquapendente and Orvieto.
