The original foundation of the church of St. Michael is due, according to tradition, to the Queen Theodolinda that contributed to the construction of this and other churches in the city after the death of her husband Agilulfo in 615. Built in Longobard style, the church was rebuilt at the end of the twelfth century.

Columns divide the interior into three naves and a notable artistic heritage adorns its wall, of which the most outstanding is the fresco of "The Last Judgement" found in the semi-domed apse.
