Saint Ambrose, Catholic church in Brugherio, Italy

Sant'Ambrogio is a church in Brugherio that blends Romanesque and Gothic elements, featuring a stone altar and decorated wall surfaces throughout its interior. The building incorporates various architectural components that shape its overall appearance and spatial division.

The complex belonged in turn to Benedictine nuns, Augustinian nuns and finally the Humiliati, who in 1539 moved to Santa Caterina la Chiusa in Milan while keeping ownership. A 12th-century church stood on the site; Cardinal Federico Borromeo's 1596 pastoral visit found it architecturally precarious, prompting restorations until 1621. After Napoleon suppressed the monastic orders, farmhouse and church passed to private landowners.

The name comes from Saint Ambrose, who according to tradition gave this land to his sister Marcellina; Petrarch mentions her rest here in De vita solitaria. The 15th-century frescoes show Ambrose, Marcellina and Satyr with Saints Sebastian and Pope Fabian, and Ambrose appears young rather than as the usual old bishop. Since 2009 the church and farmhouse have featured in the Ville Aperte programme.

The building is located on Via dei Mille 112 in Brugherio and participates in local cultural programs that promote arts in the region. Visitors should note that this is an active place of worship with specific opening times tied to religious functions.

Petrarch, in De vita solitaria, names this site as the place where Marcellina found rest, calling it a "Church of Sant'Ambrogio Ad Nemus" in his day. The 1886 restoration also uncovered 14th-century frescoes in which Ambrose and Saint Sebastian appear as young men, unlike the usual iconography of an aged bishop.
