San Maurizio al Monastero Maggiore: History & Frescoes

The Divided Church of Corso Magenta

Located on Corso Magenta in central Milan, San Maurizio al Monastero Maggiore stands along a prominent cultural axis near Santa Maria delle Grazie and the Castello Sforzesco. Rebuilt in the Renaissance style between 1503 and 1518, the church represents the collaborative work of architects Gian Giacomo Dolcebuono and Giovanni Antonio Amadeo, with completion overseen by Cristoforo Solari. Its exterior presents an understated façade made of grey Ornavasso stone, which was completed later in 1574.

Behind this sober street entrance lies a distinctive architectural layout. The church was constructed as a single nave split straight through the center by a solid stone partition wall. This division created two separate realms within a single building: the outer hall (Aula dei Fedeli) reserved for public worship, and an inner chamber (Aula delle Monache) designed exclusively for a community of enclosed Benedictine nuns.

The Public Hall and the Cloistered Nuns' Space

The partition was designed to enforce the strict isolation of the convent. Behind the dividing wall, the Nuns' Hall was constructed on a substantially larger scale than the public half of the church. The enclosed noblewomen took part in the liturgy without being seen by outside churchgoers, observing the mass through an elevated iron grating in the partition and receiving communion through a small, shuttered hatch.

A transition through a low, narrow side corridor beside the public altar leads directly into this concealed space, where the acoustic atmosphere opens beneath a vaulted starry ceiling dotted with painted angels and evangelists. The nuns' choir also houses a historic mechanical pipe organ, built in 1554 by Gian Giacomo Antegnati.

The Fresco Cycles of the Milanese Renaissance

Often called the "Sistine Chapel of Milan," the church interior contains a nearly unbroken cycle of sixteenth-century frescoes. The decorative scheme offers Milan's most concentrated in situ collection of work by the Leonardeschi—artists operating under the direct influence of Leonardo da Vinci's Milanese workshop. The primary painter was Bernardino Luini, whose sons Aurelio, Giovan Pietro, and Evangelista also contributed extensively, alongside Simone Peterzano and Antonio Campi.

The frescoes contain numerous distinctive narrative details. In a Noah's Ark scene painted by Aurelio Luini, unicorns appear among the pairs of animals boarding the vessel alongside giraffes and domestic livestock. In the Besozzi Chapel, Bernardino Luini depicted the beheading of Saint Catherine. According to a contemporary account by author Matteo Bandello, Luini modeled the face of the saint on Bianca Maria Scapardone, the Countess of Challant, who was publicly executed for murder at the nearby Sforza Castle in 1526.

Ancient Origins and Aristocratic Patronage

San Maurizio was built directly over the ruins of Roman Mediolanum, incorporating elements of the city's ancient circus and fourth-century fortifications. Two Roman towers still stand within the monastery cloister. A female Benedictine monastic community had occupied the grounds since the eighth or ninth century, originally dedicated to the Virgin Mary. In 964, Holy Roman Emperor Otto I presented the monastery with a relic of Saint Maurice, prompting its rededication.

During the sixteenth century, the reconstruction and extensive fresco campaigns were heavily financed by prominent Milanese nobility. Patrons included Alessandro Bentivoglio and his wife Ippolita Sforza, whose daughter lived inside the cloister as a nun. Monastic life continued until 1798, when Napoleonic secularization decrees dissolved religious houses. The convent was subsequently repurposed as a military barracks, a school, and a hospital. In the 1960s, the monastery cloister was converted to house the Civico Museo Archeologico di Milano.

Liturgical Life and Public Access

San Maurizio al Monastero Maggiore remains a consecrated Catholic sanctuary. On Sundays from October through June, it hosts Byzantine Rite liturgies celebrated in Greek following the Italo-Albanian tradition. The space also serves as an acoustic venue for sacred and classical music concerts.

Access to the church is available to the public from Tuesday through Sunday with free admission. Daily visitor operations and welcoming services are managed by volunteer members of the Touring Club Italiano as part of the Aperti per voi initiative.
