The large hall, which overlooks the square and dominates it from above, features two sets of Vicars' coats of arms, some older and fragmentary, above a faux stone frame. These include the Pitti (a band grafted silver and black), the Pandolfini (azure with three swimming dolphins, one above the other), the Mazzinghi, represented by a female figure with well-defined breasts, and others that are anonymous. In some places, the Red Dolphin, symbol of Pescia, appears. Below the frame, a continuous band painted with other Vicars' coats of arms from the 15th to the 18th century runs. At various times, the Vicars' coats of arms had been painted randomly on the walls of the hall. Then, during the works that affected the palace starting in 1719, during the time of Vicar Giovanni Gori, it was decided to give them a certain order by repainting them on the new plaster.
