The Villa Adriana is an exceptional complex of classical buildings, created in the 2nd century A.D. by the Roman emperor Hadrian. It combines the best elements of the architectural heritage of Egypt, Greece and Rome. The villa was a sumptuous complex of over 30 buildings, covering an area of more than 120 ha on the slopes of the Tiburtine Hills: most of them are still not jet excavated.
The Villa included palaces, several thermae, theatre, temples, libraries, pools, fountains and gardens, nearby quarters for praetorians and slaves, and a complex system of underground passages.
Since 1999 Villa Adriana is a UNESCO World Heritage Site.
