Vault. The Hall of Birds, probably born due to the restoration in 1760 by the proyect of Ennemond Alexandre Petitot, gives his name from the huge barrel which caracterizes it: 204 rounds with white frames and blue background contain many stuccoes representing flying birds. In spite of the repetition of the subject, many astuteness provide the eye of who watches not to get bored while admiring the barrel: the chromatic combination, little insertions of plaster which adorn the octagonal frames, the different poses of the birds. The vault was decorated by the plasterer Benigno Bossi who, after his coming to Parma around 1759 and his collaboration with subjects such as Boudard and Petitot in the following years, since 1766 gives his service to the borbonic court, who put him to the use of the central hall in the nobility floor of the Palazzo Ducale's Garden.
