The Duomo (Cathedral) of San Giovanni Battista (St. John the Baptist) dates from the 19th century. It is an example of Baroque architecture, designed by the Lonato architect Paolo Sorattini and built during the second half of the 18th century. Its balanced cupola (20 meters of diameter and 60 meters high) and facade soberly decorated with marble are the basilica's most notable points. The Baroque interior is enriched with frescoes and altar pieces by Venetian artists such as Antonio Balestra and Giambettino Cignaroli.
