The bestiary of the 14th Century murals is extremely rich in medieval symbols.
The Camera Domini (the lord's bedroom) was the bedroom of the counts and the dukes of Savoy. it was created in the 13th century under Peter II of Savoy and then completely refurbished in the 14th century. The painted decor dates from that period.
Remnants of murals show animals in the middle of lush vegetation. Lilies and crosses adorn the ceiling. The latter, which allude to the coats of arms of Savoy, were cut out of shiny sheets of tin.
The spiral staircase, built in about 1336, allowed the lord of the castle to climb up to the ramparts or go down to his private chapel.
