It is so named because of the thirteen paintings representing battles by various 17th- and 18th-century artists (Rugendas, Bergognone, Graziani, etc.).

At the sides of the fireplace, two 19th-century Tuscan firewood cabinets. The large still lifes are by an 18th-century Piedmontese master. In the corner, on an 18th-century table, an extremely rare Buddhist monk made of red amber, the fossil resin of the cherry tree. By the window, an important 18th-century Lombard bureaux; on the wall, the portrait of Roman emperor Otone, of Tizian’s workshop. The honour medals are the ones conferred to Giovanni Barbavara di Gravellona who was the first General Postmaster of the Italian Kingdom and the promoter of the Universal Postal Union.
A table with a showcase displays a collection of ivories, alabaster medallions and hard oriental stones
