The Villa was the suburban residence of Emperor Hadrian (reign: 117 - 138 A.D.), who began its construction near Tivoli when he returned to Rome in July 118. It originally consisted of magniloquent residential structures, luxurious thermal buildings, majestic nymphaea, hanging gardens, pleasure pavilions and plenty of fountains with water games. The architectural complex, which extended over roughly 120 hectares (presently one third is open to the public), was probably conceived by the Emperor himself as a demonstration of Power.
When the original complex was abandoned, nature gradually reappropriated the site which thus lost its identity and became known as Old Tivoli. Due to a new sensibility and the rediscovery of the impressive ruins in the time of Pope Pius II Piccolomini, the area was recognised as the Imperial residence of Tivoli and became a new source of inspiration for architects and artists, attracting ever greater numbers of students and travellers. The original complex had been divided into different properties and the area converted to agricultural use with plantations of vineyards and olive groves: an ancient olive tree (known as “Alberobello”) near the Canopus is a monumental witness to this productive phase. Areas which are still gardens show the original alternation of architecture and open spaces designed within peristyles and courtyards embellished with fl owerbeds, hedges and pergolas, frequently around pools or channels of water, modelling the natural spaces of the tufaceous plain between tributaries of the nearby Aniene river. The garden surrounding the Pecile lake is exceptionally big, enclosed by a quadrangular portico, whose colonnade is now imitated by cylindrical bay trees.
Villa Adriana has been the property of theItalian State since 1870 and was listed as a Unesco World Heritage Site in 1999. It became an integral part of the “Villa Adriana e Villa d'Este” Institute, MiC, in 2016.
