Palazzo Venezia, the Cancelleria, Palazzo Barberini, ST. Peter's Basilica, the facade of the church of Sant'Agostino and the Porto di Ripetta were all built with blocks of travertine extracted from the ruins of the Colosseum. A well known saying goes: What the Barbarians didn't do the Barberinis did! Threatened with demolition by Sixtus V for urban reasons, it was finally declared a sacred monument and dedicated to the Passion of Jesus Christ by Benedict XIV. Ever since it has been an object of adoration for the faithful and preserved from further destruction.
Il Palazzo Venezia, quello della Cancelleria, il Palazzo Barberini, la Chiesa di San Pietro in Vaticano, la facciata della Chiesa di Sant'Agostino e il Porto di Ripetta, vennero appunto, costruiti con blocchi di travertino estratti dalle sue macerie.
