[1] The most notable part of this green space is represented by the large number of villas and landscaped gardens created by the Italian aristocracy.
They were based on the gardens of the consul Aelius Lamia, a friend of Tiberius, and soon (by the time of Caligula) became subsumed into the imperial property.
The Horti Liciniani[2] were a set of gardens in ancient Rome, which originally belonged to the gens Licinia.
The Villa Borghese gardens still cover 17 acres (69,000 m2) of green on the site, now in the heart of Rome, above the Spanish Steps.
The gardens, which were enriched with many additional structures in the four centuries during which they evolved, contained many pavilions, a temple to Venus, a porticus of a thousand paces, and monumental sculptures.
The Emperor Nerva died of a fever in a villa in the gardens in AD 98, and they remained an imperial resort until they were sacked in 410 by the Goths under Alaric, who entered the city at the gates of the horti Sallustiani.
The ancient topography itself has been irrevocably altered with the filling of the valley between the Pincio and Quirinal hills where these horti existed.
They were then divided into different properties, were partly reunited under Gallienus in the mid 3rd century, but began to split again, in late antiquity being centred round the residence of Vettio Agorio Protested as the Horti Vettiani.
From this area come numerous attributable sculptures from the Gardens's different phases : statues of deities, decorative reliefs, two large marble craters and three splendid portraits of Hadrian, Vibia Sabina and Salonia Matidia.
[8] Since the 17th century the nymphaeum has frequently been wrongly identified with the Temple of Minerva Medica mentioned in literary sources, on account of the erroneous impression that the Athena Giustiniani had been found in its ruins.
The Caffarella Valley (now the park) is bordered on its northern side by the Via Latina and on its southern by the Appian Way, and extending lengthways from Aurelian's Wall up to via dell'Almone.
The park is in the northwest area of the city of Rome, in Municipio XIX, shared between the districts of Aurelio, Primavalle, and Trionfale.
