Back in the 16th century, Cardinal Ippolito II d'Este was given control of Tivoli, Italy, since he failed to become pope. He decided to build gardens and villas that would equal the grandeur of Rome at his own house.
The steep, terraced landscape is filled with grottoes, sculpture, and statuary, but the dominant feature is water, which d’Este’s architects channelled into burbling canals, ponds, and a multitude of fountains. Amazing, isn't it!
The "faces" you can see are part of the Hundred Fountains. I like the Hundred Fountains the best. All the figures are slightly different. On a hot day, the fountains cool you off. More importantly, they seem to be whispering, "What secrets would you like to share with me?"
There is also a water powered organ, which you can see in the video on the final slide!
