The entrance of the palace leads into the Cour d'honneur ("Honour Court"), which once housed a fountain with a deer.
The interiors originally housed a large collection of stuccos, statues, paintings (according to Amedeo di Castellamonte, up to 8,000) from some of the court artists of the times, such as Vittorio Amedeo Cignaroli, and Bernardino Quadri.
