This room and the following two were renovated in 1797, during the Napoleonic age, when the Municipal Palace was refurbished, in order to house the new Republican Directory.
The painted decoration, an Allegory of Virtues and Arts, is the work of Giovanni Battista Frulli (1765-1837) and Francesco Stagni (1747-1830).
The ceiling is subdivided into monochrome architectural frames, like those in room 14. In the middle, inside an oval framed by a hexagon, are several musical instruments, laurel wreaths and sheet music. Four monochrome squares, inscribed in ovals with a pink background, frame the Cardinal Virtues.
In the four corners of the room are triumphs of arms with medallions on top. On the two overdoors, against a blue background, are the allegories of Peace and Abundance.
