The upper garden & houses of the Muses at Villa Lante, a large estate where two different Cardinals commisioned homes and an extensive garden during the late 1500s.  The design of the garden & engineering of the fountains has been well regarded from the beginning.  Michel de Montaigne visited here on his Italian journey in the 1580s and noted, "it seems not only to equal but to surpass both Pratolino and Tivoli... it has much more art, beauty, and grace... certainly, if I know anything about it, this place easily takes the prize for the use and service of water."
