The emperors would leave Rome for various reasons. Some had greater mobility and travelling was a way to do propaganda and to reveal their ecumenical program: their journeys, besides being frequent, were often directed towards the provinces, and some in particular. The most well known case is that of Hadrianus and his inclination for the eastern area of the empire as for Egypt. Many residences, renowned for their dimension and magnificence, were scattered along the Campanian coast, so rich in archaeological remains. Not a few locations on the Bay of Naples enjoyed considerable importance in being greatly appreciated by many of the most influential senators and the emperors themselves, who went there to enjoy the hospitality of generous hosts. Only the imperial villa at Baia – a special case in the multifaceted landscape of the Campanian coast – was attended from the Julio-Claudians up to the Severi.
