With this step the configuration seminary route became simplified: ginnasio in Seveso, liceo in Monza and theology in Milan.
Following the apostolic visitation of abbot Alfredo Ildefonso Schuster, then Archbishop of Milan, the site of Venegono Inferiore was built with the intention to move the center of the seminary there.
In the following decades, when the liceo classico and the last three years of theology were placed in Venegono, several locations were used: Seveso (medie-ginnasio), Masnago (elementari-medie), Arcore (medie), Merate (medie), Seminarietto del Duomo (ginnasio-liceo), Saronno (biennium theological and comunità propedeutica), Milano (adult vocations).
In 1966 Cardinal Giovanni Colombo decided to transfer the theological faculty (built by Pope Leo XIII in 1892) from Venegono Inferiore to Milan, thus forming the Facoltà Teologica dell'Italia Settentrionale.
The restoration of the permanent diaconate wanted by Cardinal Carlo Maria Martini in 1986 found a place in the headquarters of the Seminary.
