Many artistically and historically significant buildings, structures and churches were demolished for the construction: among them, Palazzo Altoviti, the Teatro Apollo at Tor di Nona, Sant'Anna dei Bresciani, the Ripetta Harbour, the Roman Pons Cestius (pulled down and rebuilt with wider side arches), the already damaged Roman Ponte Rotto (of which only one arch remains), some minor gates of the Aurelian Walls flanking the left bank. The Ponte Sant'Angelo was widened too, adding two more arches. Along with these structures, the erection of the Lungotevere provoked the loss of one of the most picturesque environments of the city.
