The Council Chamber houses Art Nouveau frescoes by Marcello Nizzoli.

Born in Boretto in 1887, Nizzoli became an internationally renowned artist, best known for his work in design and signage. In 1911, he was commissioned to decorate Boretto’s Council Chamber. These frescoes, among his earliest works, are an excellent example of the decorative art of the early 20th century.

On the western wall, two allegorical figures are depicted: Father Eridano (Eridanus) and Mother Cerere (Ceres). Above the entrance door hangs the municipality’s emblem, the Gonfalon, while the central scene - featuring bacchantes (maenads) - symbolizes the cyclical nature of human passions. The southern wall portrays the personification of Justice, holding an olive branch, framed within a cross-shaped design. 
Suspended from the ceiling is a wrought-iron chandelier designed by Nizzoli and crafted by Renato Brozzi. This piece reflects the style of the entire decorative scheme, embodying the refined naturalism also present in the ceiling’s friezes.
