The monastery, dedicated to
Saint Ambrose but also known as Our Lady of the Lamb of God, was founded in 1349 by
Giovanni Visconti, bishop and lord of Milan. Soon after the foundation, monks from this monastery, with the patronage of
Galeazzo Visconti, helped found the
Certosa of Pavia. It was then located some 4 kilometres from the walls of Milan. In the 14th century, it housed, among others, the poet
Petrarch. It was pillaged in 1449 when the Visconti dynasty fell. It was suppressed under the rationalist reforms of the
Emperor Joseph II, Milan then being under Austrian rule, and became a parish church in 1782. In 1960 the surviving buildings and parochial duties were taken over by the
Capuchin Friars. The present buildings date from the 16th and 17th centuries. The main artworks include a cycle of frescos in the main church by
Simone Peterzano (1578), il Genovesino, and
Daniele Crespi (1629). There is a painting of
San Brunone by Crespi. The
chapter house contains, in the vault, a fresco of
Saint Michael by
Bernardo Zenale of the early 16th century. ==Further reading==
