The decorative scheme, similar to that of the Throne Room, is attributable to the ideas of Domenico Parodi, while the execution was carried out by workers from Italian-speaking Switzerland. The decorations, such as the central head surmounted by an element that takes up the wavy surface of a shell, find similarities with some details of the Sala delle Battaglie. As regards the chronology, the vault of the Sala del Veronese should also rotate around the middle of the fourth decade of the eighteenth century, probably part of the same renovation program decided by Gerolamo Ignazio Durazzo on the occasion of the wedding of his daughter Maria Maddalena with his cousin Marcellino in 1734. However, this is a proposal that relies largely on stylistic observations, without any documentary confirmation having yet come to shed light on the issue, therefore destined for future verification.

Vault and walls are decorated with polychrome and gilded reliefs that simulate flowering branches and branches inhabited by birds, on a light blue-gray background. The vegetal element recurs above the slender cornice and in the carvings of doors and over doors. The color scheme is delicate with bright and bright colors: ranging from light green-beige, teal and dark green of the leaves to pink and carmine red of the mottling of most of the petals, to intense blue and blue of some flowers; everything stands out against the light blue-gray background. The style seems close to that of the stuccos made in Genoa and Liguria by artists from the valleys of Italian Switzerland, near Lake Como. The themes of the three overdoors, in accordance with the dictates of Rococo fashion, are also found in a living room of the Apartment of the Ladies on the first mezzanine floor, where the plastic decoration is performed with extraordinary technique and refinement.

Stuccoes on the walls of the Ballroom A voluminous frieze runs along the perimeter of the room, clearly separating the ceiling from the walls. The latter are marked by high Corinthian stucco pilasters that form 14 regular spaces. The highest part of each space is decorated with a box with three maenads inspired by classic models. The center of the two short walls is instead marked by an arch with winged figures and in the center a tondo inspired by the Dionysian theme.
