Villa d'Este is acclaimed for its elaborate water gardens and statuary.  Waterfalls burble and fountains gush all over the place, and the effect is that the entire area is a cooling oasis throughout the warmer months.

At the end of the Canal Garden is a collection of random (it seems) statuary.  To the right of the standing figure is a representation of Romulus and Remus who are considered to be the founders of Rome. Click it.
