Although this wide rectangular room is usually referred to as the "Sala Piermarini", the chamber, which is located on the top floor of the theater just above the entrance hall, is dedicated to Empress Maria Theresa, as is indicated by a large marble plaque, placed under two winged male figures and above a fireplace. The room was designed by Paolo Pozzo, who created a bright space adorned by representations, that on the one hand honour the great Empress and on the other exalt genius, intelligence, the arts.The bas-reliefs of the hall are the work of Ticino Stanislaus Somazzi, designed by painter Giuseppe Bottani (1717 Cremona, Mantua 1784), director of the Academy of Fine Arts.
