8) The Gardens of Chateau de Villandry.
There is perhaps no better place to see that European equivalent of manicured symmetry than these gardens in Indre-et-Loire, France. There is a spectacular pattern of box hedge and flowers that look incredible from above.
There are actually six gardens over six terraces, with plenty to explore. The Sun Terrace at the top and Herb Garden at the bottom add different sensory experiences to your visit.
