Casa Cavassa is one of the symbolic buildings of the Saluzzo Renaissance, the residence of Galeazzo Cavassa and his son Francesco, belonging to a noble family originally from Carmagnola (a flourishing commercial center and a strategic outpost for defense against the threats of conquest by the Savoy, belonging to the Marquisate of Saluzzo since 1100). Probably Galeazzo Cavassa acquired the building after 1450 without making major changes to the medieval structure (still evidenced today by the pointed arch windows on the facade of Via San Giovanni). In any case, the choice to make this building the official residence of the Cavassa family in Saluzzo is not random, as the house is located near the main buildings of religious power (the church and the convent of San Giovanni) and political power (the marquises' castle and the ancient municipal palace).

Today, the museum tour is developed on two floors, the ground floor and the first floor, presenting a sequence of 15 rooms with painted wooden ceilings and decorated walls, while the underground areas are used for exhibitions and educational activities. Among the works exhibited inside the rooms, we can mention: the painted and gilded panel depicting the Madonna of Mercy by Hans Clemer (1499) and the late Gothic wooden choir from the chapel of the Marquises of Saluzzo in Revello (room 5); the polyptych The Adoration of the Magi, a work by Jacobino Longo, dated 1530 (room 9); the portraits of Carlo Emanuele I of Savoy and his consort Caterina d'Austria, painted by Giovanni Caracca around 1590 (room 13).
