Located just outside of Tivoli, Villa Adriana is a collection of classical buildings created in the second century under the orders of Emperor Hadrian. It was a “small town” consisting of palaces, fountains and baths, as well as other structures that mimic various Greek and Egyptian architectural tyles.The construction of Villa Adriana came about due to the fact that Adriano was unhappy in the palace on Palatine Hill, and he created it as his place of retreat.The Canopus, an enormous pool surrounded by columns, is a copy of a sanctuary located near Alexandria.
