 In 1821, with a legacy of Canon Marco Celio Passi, it was possible to acquire several buildings near S. Maria in Monte Santo, which made possible the reunification of the entire student body in one residence.The seminary buildings were so deteriorated by the end of the 1950s, however, that Bishop Giuseppe Piazzi was compelled to rebuild the seminary, for which he had the support of Pope John XXIII, who had taught at the seminary, and Cardinal Gustavo Testa, a native of Bergamo.The project was finally completed in 1967.
