The Duomo is the first and most important Marian shrine of the city and of the diocese of Milan. This is recalled by the dedication Mariæ Nascenti (to the Virgin Mary as she was born), placed on the façade during the Napoleonic era, replacing the previous one dating back to 1645, which bore the date of the foundation of the church: Deiparæ Natali - civitas - MCCCLXXXVI (the city - to the Nativity of the Mother of God - 1386). But it is above all the statue of the Virgin Mary, the Madonnina, which was placed on the summit of the top spire of the cathedral at the end of the year 1774, that indicates the dedication of Milan Cathedral to the Virgin Mary.
Since the start of the construction of the Cathedral the Veneranda Fabbrica has entrusted itself to the maternal intercession of the Virgin, who has protected its work since 1387. The ancient winter basilica, which stood where the central nave of the Cathedral now is, was already named after Santa Maria Maggiore and in the new Cathedral numerous windows and altars were dedicated to her over time.
The Ambrosian Church looks to the Virgin Mary as "hope and dawn of salvation for the whole world" (prayer after communion). A person's birth is always a promising event; it was especially so for Mary, the Mother of the Lord: her birth marked the dawn of the fullness of the history of salvation.
The feast of the Nativity of the Virgin Mary (this year it has been brought forward to 7 September, because it coincided with Sunday) is the Duomo’s “patronal feast” and traditionally it marks the resumption of all activities in the Diocese. The Archbishop presides over the pontifical Mass for the Opening of the new pastoral year and the rite of admission among the Candidates to the sacred Orders, with the participation of the Metropolitan Chapter and the diocesan presbytery and of various representatives of the faithful.
