The Dominicans left the suppressed convent permanently in 1798, with the arrival of the Cisalpine Republic. It was then bought by the Milan curia in order to house the Archbishop’s Minor Seminary along with the church. The crypt was built at the start of the twentieth century and the decor was restored in 1952. An altar housing the shrine that contains the scythe used by Carino of Balsamo to kill Saint Peter Martyr in 1252 is located in the crypt. In 1923 the church became a parish, which has since been transferred to a more modern church, able to host a higher number of followers.
This Baroque-style building’s main features date back to the seventeenth century (1660-1685). The church’s facade is characterised by the overlapping of two architectural orders, separated by protruding trabeation. A triangular gable finishes the facade, which highlights the main body and whose southern side is edged by the belfry.
Today this historic Seveso seminary is used instead as the Milanese Pastoral Centre. First and foremost, the Centre is secular but since it started it has always worked closely with the training for deacons and the presbytery.
Through the Centre, the diocese takes care of training with regards to specific positions of pastoral care. Furthermore, both the Ismi (the Maria Immacolata Priest Institute), which takes care of young priests during the first five years of their training, and the headquarters of the episcopal vicar of the area are still located in Seveso.
