The villa was built in an area of Rome known as the 'Vigna Vecchia' (which was once against the city walls), lying on the slopes of Monte Parioli, as a 'Villa Suburbana' and a place of repose.
Pope Julius took a direct interest in the villa's design and decor and spent vast amounts of money on enhancing its beauties.
Only a small part of the original property has survived intact, comprising three vineyards which extended down to the Tiber, and to which the pope traveled often by boat.
This three-levelled structure of covered loggias, decorated with marble statuary, reclining river gods in niches, and balustrading, is constructed around a central fountain.
Papal parties embarked on boats at the gates of the Vatican and were transported up the Tiber to the villa's long-gone private landing stage.
It was restored in 1769 on the initiative of Pope Clement XIV, confiscated by the new state of Italy in 1870, and given over to the National Etruscan Museum in the early 20th century.
