The main attraction is the Palazzo Visconti, divided into a Palazzo Vecchio ("Old Palace") and a Palazzo Nuovo ("New Palace"). Originally a defensive castle known from the 10th century, it was rebuilt in the 13th to 17th centuries; it houses frescoes from the Galliari brothers, Mattia Bortoloni and Alessandro Magnasco.
The church of Sant'Andrea dates to the 11th century. It has a 15th-century entrance portico.
