The complex structure designed by Pirro Ligorio is made up of the Casino, the Ninfeo, and an oval courtyard with fountains and statues. The rich decoration, the statues, the shape of the spaces are all references to the past that Pius IV and Pirro Ligorio felt would foster spiritual growth. Here the Pope spent nights with philosophers and artists discussing poetry and sacred subjects. Source: www.romeartlover.it/Vasi182.htm / 'Ligorio also built the Casino of Pope Pius IV (Casina di Pio IV) in the Vatican Gardens (1558-62) and the Rotunda with Baldassare Peruzzi (1481-1536). He decorated his works with profuse stucco ornament; the Casino is a good example of his decoration.'
