Inside the Villa we find four fireplaces (Devil, Angel, Fish or Sea Monster and Lion) attributed to the genius of the sculptor and decorative artist Bartolomeo Ridolfi, which represent monsters with gaping mouths that seem to co-exist in happy contrast with the harmony and orderliness of the outdoor spaces.
The rooms were originally entirely frescoed while later, decorative moldings were added. Apart from the monumental fireplaces the rooms also preserve noteworthy vaulted or umbrella ceilings and precious frescoes.
