The brickwork bell tower (probably dating from the 12th century) has two thin Romanesque mullioned windows at the base.

The church was damaged by Austrian shelling during their successful siege of the city in 1849 during the First Italian War of Independence.

The altar background has a monochrome fresco by Agostino Mengozzi Colonna depicting Two Angels uphold the Globe.

A work by Palma the Younger (The Virgin at the Incoronation of Venice by St. Magnus) decorates the fourth altar.

In 1955 Angelo Roncalli, future Pope John XXIII and then Patriarch of Venice, had a silver mask put on the saint's face to protect it from dust.
