The city's main monuments occupy the four sides of the
piazza: the college of the
Jesuits; the Palazzo Comunale (formerly the Palazzo Apostolico), designed by
Bramante, that houses an art gallery with works of
Lorenzo Lotto,
Vouet and
Annibale Carracci as well as a collection of
maiolica, and the
Shrine of the Holy House (
Santuario della Santa Casa). It also boasts a massive line of walls, designed by the architect (and military engineer)
Antonio da Sangallo the Younger, which were erected from 1518 and reinforced in the 17th century. ==Gallery==
