The three main gates had a monumental look, with high semicircular towers. Two of them survive to this day: “Porta Soprana” and “Porta dei Vacca”; the third one, Porta Aurea ("Golden Gate"), already partially demolished in the 18th century, was completely demolished in the second half of the 20th century. In the 13th century, the Old Pier peninsula, at the southern limit of the port, was also included inside the walls, thus completing the fortifications on the sea side of the city.
