During the late republican period a magnificent residential complex was bulit on the hillside facing Sorrento. In its heyday, this villa covered an area of approximately 9 hectares including gardens, a theater, baths, vines and finds ponds. Historical sources cite the Roman knight Publio Vedio Pollione, a rich freed man originally form Benevento, as the first owner of a large villa built on the site which he called Pausilypon (meaning respite from pain in Greek) a modified version of which came to refer to the whole hill once the Greek name had been given to a villa, Villa Posilipi, a hill, Mons Posilipensis, and a hamlet; Casale Posilipi. Posillipo was the name finally given to the area.
The theater unfortunately can't be seen from the place I was standing. A long walk to the entrance just fueled my frustration about the inertion in this country.
