In the hamlet of Montesiro in Besana Brianza, in the province of Monza e Brianza, stands one of the most important Romanesque complexes in Brianza, consisting of a former women's convent and the Church of Saints Peter and Paul. Inside it houses a splendid, 16th-century painting of the Last Supper.

In the 11th century, life in Brugora, in the hamlet of Montesiro in Besana Brianza, now in the province of Monza e Brianza revolved around an ancient Benedictine convent. Next to the former convent is a church from the same period, accessible to all and dedicated to Saints Peter and Paul. Rare, fine examples of Romanesque sculpture can be found on the Church’s gabled facade.

Over the centuries, the original Romanesque-style interior was revisited with Baroque-style additions. The real treasure of all the artworks here is on the high altar: a recently discovered, 16th-century painting of the Last Supper.

Behind the altar, a wall marks the space that was originally reserved for the cloistered nuns. It is accessible from the cloister of the former convent and is covered in 16th-century frescoes. The bell tower of the Church of Santi Pietro e Paolo in Brugora is also worth seeing: it has a square foundation, also dating back to the Romanesque period, with later additions.
