It is a great baroque building with a plan of Latin cross. The impressive façade is divided by columns and adorned by sculptures depicting (from right to left): Santa Caterina d’Alessandria, San Zeno, Sant’Annone, Santa Barbara. Over the window there is the coat of arms of the Community: the rampant lion with two keys in its paws and three lily flowers above the head. The beautiful dome dominates the Basilica and elevates itself harmoniously: it is an example of the production of the architect Paolo Soratini from Lonato (1680-1762). Inside there are thirteen altars, the principal one is completed by an extraordinary altar piece depicting the Sermon of San Giovanni Battista, finished in 1752 by the painter Giambettino Cignaroli. The sacristy conserves the triptych from the Renaissance period signed by Bernardino Licinio in 1528.
