On the south side, there are two twin baroque churches, the Santa Cristina (1639), designed by Castellamonte, and San Carlo, built in 1619 and attributed to various architects including Castellamonte. The concave side of the first, was redesigned in 1715 by Filippo Juvarra. The facade of the church of San Carlo is instead of Lombard Caronesi Ferdinand (1836).
Being in the center of the town, rarely to be seen quiet and calm, somehow in last summer one early before noon, happened to witness the square in a slightly different light.
