Bonsignore's pupil in Turin, resident in Rome from 1818, he built in the elegant but cold propylaeums in Greek style of Villa Borghese, the Egyptian prospects of the same, the Vagnuzzi country house in Porta del Popolo, etc. Quite notable are his numerous studies on ancient monuments: Ancient architecture described, Researches on the most proper architecture of Christian times, The buildings of ancient Rome, Historical description of the Roman Forum, etc. Ti him we owe the monumental arrangement of Via Appia antica.
