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. This project was quickly abandoned after the establishment of the new capital, Milan, of the Cisalpina Republic.
The neoclassical decorations of the room, hidden during the 1930s, were discovered in the 1980's. The present ceiling is decorated with panels in the Neo-Pompeian style, showing fake monochrome reliefs against a red and blue background.
These scenes represent triumphs and sacrifices, thus celebrating the victory of the Republic. Over the doors, inside square frames, are inscribed circles in false red marble bearing pairs of monochrome figures, made to imitate antique cameo bas-reliefs.
The decorations, partly repainted in some areas, are believed to be early works by the Bolognese neoclassical artist Pelagio Palagi.
