Listed as a UNESCO World Heritage Site in 1999, Villa Adriana (Hadrian's Villa) stands in the municipality of Tivoli in the Province of Rome between the slopes of the Tiburtini Mountains and the Roman countryside. As its name suggests, it was the suburban residence of Emperor Hadrian, who chose the green and water-rich territory of ancient Tibur.

The construction of the complex took place between 118 and 138 A.D. and covered about 120 hectares, including residential structures, baths, nymphaea, pavilions and gardens. Currently, the area that can be visited is only about 40 hectares compared to the original 120.
