The Palazzo Visconti was built in the 17th century by Carlo Bolagnos, a Spanish nobleman. From the end of the 18th century the palace passed through various hands until, between the end of the 18th century and the beginning of the 19th century it was bought by Viscount di Grazzano and became the family residence. It is one of the most elegant examples of the Lombardy Barochetto style and the decoration in the rooms on the main floor is particularly interesting, in the style of the early eighteenth century with hints of the Rococo movement.
