This vast and luminous church is laid out in the shape of a Greek cross, completed by four side chapels. Its baroque decoration was carried out from the late 18th century to the mid-19th century, in a style typical of the rococo period. Don't miss : the murals, the altar-pieces surrounded by fine stuccos, the polychrome marble balustrade in front of the high altar, the organ and its magnificent polychrome wood casement.
