San Maurizio, Religious building in Piazza Santa Margherita, Monza, Italy.

The chiesa di San Maurizio in Monza has a two-tiered reddish-brown brick facade with a triangular gable topped by three white statues: angels at the slopes and Saint Margaret at the apex. A central arched window sits between tall shallow brick panels, and a white stone cornice separates the upper level from the lower, where a sculpted portal frames a wooden double door with a relief bust of the saint in a central medallion flanked by two small white figures.

The church originated in 1310 on the site of a Humiliati house, later a convent. In 1469 a new church dedicated to Saints Margaret and Catherine replaced the medieval oratory. After structural decay, Giacomo Antonio Quadrio rebuilt it entirely in 1736; the monastery was suppressed and the church deconsecrated in 1785. Since 1881 it has belonged to Monza Cathedral, which transferred here the title of the old San Maurizio church demolished in 1846.

The vault frescoes over the first three bays were painted by Carlo Innocenzo Carloni between 1740 and 1742, with panels by Giuseppe Castelli and Perrucchetti completing the decoration. The walls hold canvases by Antonio Maria Ruggeri, Ambrogio Brambilla, Giambattista Gariboldi and Francesco Corneliani. In the counter-facade, inside a Baroque frame, hangs the city's oldest bellows organ, from the 18th century.

The church stands on Piazza Santa Margherita, separate from the Duomo, so it is reached on foot through the square rather than through the cathedral. The old convent entrance portal is visible on the wall to the left of the facade, and to its right is the opening that once held the foundlings' wheel. The bell tower in terracotta with marble balustrades rises behind the church on the right.

The two granite columns flanking the portal are set on a diverging splay line, not parallel to the door jambs. The oval medallion between the praying figures holds the bust of the saint. Left of the facade, the old convent entrance portal and the wheel where abandoned newborns were left still survive.
