The Uccelliera (aviary) was designed by Girolamo Rainaldi in XVII century and features the heraldic symbols of the Borghese, eagles and dragons, depicted in the facade. According to historical documents dating back to 1616, rare and precious birds could be seen by visitors in the aviaries located in the vaulted gallery.
In the past centuries, many Roman villas had an aviary, sometimes a painted one or a real one.
