The Salvatore Besso Conference Room was Salvatore's room, a large room divided by screens into zones: night, work and study, a house within a house.

In the vault it presents an allegorical decoration with six lateral lunettes and two central ovates.

The decorative theme is linked to the exaltation of the arts, with sciences and geography represented in the lunettes, and literature, history and music, in the two central ovates.
