Excavations undertaken in the south-eastern part of the forum where, on the Masseria del Gigante property, a temple of imperial date had been uncovered, confirmed the typology of the complex. This closed rectangular courtyard and portico with a temple on a high podium was situated in the middle of the short side of the forum. The temple had very close parallels with the so-called “temple with portico” in the same town. Amongst the finds was a large fragment of a draped female statue in Italian marble, reproducing a 4th century B.C. type. It is likely that the statue stood in a semicircular niche in the back wall of the northern side. The chronology probably still falls within the Domitianic period, to the period of the renewal of Cumae following the opening of the new via Domitiana.

Recently, the collapse of another interesting building emerged north of the Masseria del Gigante, in the south-eastern corner of the forum. This was a structure in tufa opus quadratum, the first order of Doric columns, the second order of Ionic columns and the inner faces of the arches decorated with rosettes. This monumental façade was decorated with high relief figured balustrades which seemed to reproduced in architecture the perspectives of II style painting (for example the villa at Oplontis). The opus quasi reticulatum technique used for the walls of the rooms extending behind the façade has a parallel in the so-called “aula of Sulla” in the same town, suggesting the same late Republican dating.
