It was built as Ducal Chapel by Azzone Visconti in 1330, and finished in 1336, as indicated by an inscription on the walls.

[1] The octagonal bell tower has the first example of public clock (before, sun-dials were used).

The interior was restored in the Neoclassicist era by Giocondo Albertolli.

Of the original church, part of the Giottesque Crucifixion, a canvas with St. Charles Borromeo by Giovan Battista Crespi and the tomb of Azzone Visconti remain.
