A direct connection to Trastevere with a postcard background in which you can see the dome of St. Peter's Basilica, is created by the romantic Ponte Sisto, built by Pope Sixtus IV della Rovere (1471-1484), on the occasion of the Jubilee of 1475, to allow direct communication between Trastevere (and the Vatican) and the rest of the city.
The bridge consists of four arches covered in travertine marble. It has a central circular opening and is decorated by five marble papal coat of arms. The problem of the identification of the author of the project remains unsolved, with the attribution of Vasari to the Florentine architect Baccio Pontelli (c.1450-1492) having been disproved by that the fact that he arrived in Rome only after it was built.
After the unification of Italy, due to the growing needs of traffic, in 1877, it was decided to increase a section of the bridge by adding two metal walkways suspended on corbels designed by Angelo Vescovali (1826-1895).
