A 2nd Century pagan temple, which was turned into a church by the Holy bishop of Antioch, of St Babila. The church was rebuilt between 1096 and 1097, with a covered central nave and four spans. It was built in the Visconti era and in the Baroque period with the addition of a frontal span which changed the outward appearance. The restoration of the facade and the rebuilding of the bell tower in a New-Visconti style were planned by the architect Bianchi who renovated the church in 1906. Alessandro Manzoni was baptised in this church on the 8th March 1785.
