The frescos of the hall represent some scenes inspired by the "Gerusalemme Liberata" of Torquato Tasso: work of the bolonaise Alessandro Tiarini, big amount of representations were lost due to the scialbatura. Along the western and eastern walls there is a skerting board decorated with cherubs and shields, ideal continuum of the Mirola/Zanguidi one in the Hall of Ariosto. The nortern and the southern part interrupt the narration: they host, respectively, an alcove finely decorated with stuccoes of Carlo or Benigno Bossi and a landscape connected to the theme of the "Gerusalemme Liberata" of unknown artist.
