New excavations were undertaken in the area in front of the Temple of Augustus in order to document the structure in view of the creation of a project for its restoration. New data came to light regarding the complex building history of the urban quarter around the ancient temple, later a cathedral, where between the 16th and 17th centuries profound and complex transformations took place. As well as adding to knowledge of the material culture of this period, the excavated levels produced numerous finely made Roman architectural and figured marbles. The latter comprised a male portrait, another fragment of a head with a thin fillet around the neck, a female head perhaps of a caryatid. There were also three fragments of a marble inscription mentioning an act of euergetism carried out in teatro by several Augustales in 11 A.D. The inscription is further confirmation of the presence of a theatre at Puteoli, to date unidentified on the ground but represented on the known flask incised by Odemira.

The most important piece of topographical data for the Roman period was the presence, in front of the temple, of a large square which may have acted as a forum until the 1st century A.D. It was paved with limestone slabs and supported by a series of cisterns, cut into the tufa bed rock in the Republican period. Once freed of the post-antique structures the access stairway on the west side, with white marble steps, came to light together with the remains of the enclosure that delimited the sacred area. As to the east, this comprised a wall with rectangular niches framed by pilasters and brick half-columns.
