Excavation and restoration continued at villa Pausilypon, built by the equestrian Publius Vedius Pollione from Benevento and left by him to Augustus. The investigation looked at the odeion, completely uncovered in the first excavations of the 19th century by Mons. Di Pietro. Facing the theatre and abutting a hill directly above the sea, the building faced onto a garden with a long portico of brick built columns faced with plaster. The odeion built in the early Augustan period and inserted into a large rectangular hall with opus reticulatum walls, comprised a small cavea of six tiers and a low rectilinear stage. Perhaps during the Neronian period the structure was monumentalized by the addition at the centre of the scaena of an apse with four large niches and of an imperial aula above the summa cavea.
At the centre of the aula an apse in opus latericius housed a statue of the emperor, of which part of the masonry base was preserved. The hall was entered from the side via ramps, necessary for the transit of the princeps’ litter and perhaps for sacrificial animals. A heightening of the stage dated to a subsequent phase (still within the 1st century A.D.). The stage was given a frons prosceni with semicircular and rectangular niches, and the final three tiers of the cavea were built. Perhaps damaged by an earthquake, the theatre building was not restored. It finally collapsed at the end of the 1st century A.D. or shortly afterwards.

Exploration of the surrounding area concentrated on the main entrance to the odeion, a large quadrangular hall (circa 15 m long) and a beautiful opus sectile floor (African, giallo antico, portasanta and pavonazzetto marbles). The lower parts of the walls were veneered with marble, the upper parts decorated with plaster and frescoes. Fragments of the statues and their bases that adorned the adjacent garden were found.
