A 15th-century building, re-structured in the following century in renaissance style. The facade on the first floor is decorated with false renaissance windowed ashlar-work and on the second floor with original lancet arches. The marble 15th-century portal is by Sanmicheli.
The building today serves as the Civic Museum. Many of the rooms have frescos, period furnishings, works by piedmontese painters from the 14th to 19th century and relics of Silvio Pellico. It is well worth visiting for the panel entitled " Madonna della Misericordia" attributed to Hans Clemer.
