In 2013, research continued along the eastern and western margins of the basalt-paved space in front of the Porta mediana. The area immediately north-east of the gate underwent radical restructuring during the Domitianic phase, accompanied by the obliteration of the secondary road that headed east, by the destruction of several funerary monuments and the laying of the basalt paving. During this significant intervention, new structures were built along the edge of the square and there was a substantial rise in the ground surfaces with the creation of a large terrace to the east of the area. A large quadrangular structure was present in the excavated area, interpreted as a threshing floor, in phase with the 18th century masseria of Matteo Scotto di Aniello il Procidiano, situated about 50 m further east.
Below the surface of the threshing floor on its southern side, the excavation revealed a complex stratigraphy made up of levels relating to at least two earlier structures with at least two building phases dating to the 14th-15th centuries. Below the latter lay walls in opus reticulatum that can be attributed to the monumental phase of the Domitianic period.

This season’s excavations also looked at a sector of the necropolis situated at the crossroads between the road travelling west and the north-south road, extending the excavation area to the funerary enclosure (A42) and the passage (A19) that closed the insula to the west. In its final phase of use, the enclosure, smaller than in the preceding phase, was more or less square. It was built in opus reticulatum and the façade was decorated with semicircular niches. The interior was occupied by “a bauletta” tombs and graves with “a cappuccina” coverings. The monument preserved part of the original coloured wall plaster, datable to between the late 1st and early 2nd century A.D.

In 2013, important excavations were undertaken in an area situated along the eastern edge of the south-north road at about 100 m north of the gate. A necropolis dating to between the second half of the 2nd century B.C. and the first half of the 1st century A.D. was investigated. In particular, a mausoleum with semi-hypogean chamber and barrel vault (D34) was uncovered. This season, the Center completed the intervention by digging a trench to the north of the extrados of the tomb’s vault, which confirmed its attribution to the last decades of the 2nd century B.C.

This year, the stratigraphy below the basalt paving of the via Domitiana, in front of the monumental complex known as the “Sphinx” (A63), was checked and confirmed what had been identified in the past. Below the basalt paving the road make-ups were identified in addition to three levels relating to an earlier road on top of which the via Domitiana was built. The levels produced little material; no elements contrasted with the dating of the road towards the end of the 1st century A.D. The presence of the water-table halted any further excavation.
