CASA MUSEO DI ARLECCHINO (HARLEQUIN) is located in four rooms of Palazzo Grataroli, a stately building dating back to the 14th century. The Grataroli family commissioned several frescoes to embellish the walls of their palace. Not all survived the test of time, but those that did survive are interesting, to say the least, and they can be found in the room called Camera Picta. 

The fresco that occupies the largest wall represents a jousting tournament in which the Grataroli family wins over rival families from the valley.  Patron saints venerated in the area can be recognized on the other walls of Camera Picta.
