During the 2013 campaign, the research undertaken by the Centre Jean Bérard concentrated in the area in front of the Porta Mediana, along the east side of the basalt-paved area and in the sector north of the latter, along the first stretch of the north-south road.

In the area immediately north-east of the gate, the excavations revealed at least four large scale building phases. In the second half of the 2nd century B.C., underground or semi-interred funerary monuments were built along the north-south road (e.g. the chamber tomb D46 with barrel vaulted roof, investigated in 2012). Later, several small tombs with underground chambers were built, identified in two trenches dug to the west of tomb D46. A third phase, relating to the construction of the via Domitiana in 95 A.D. and the monumentalisation of the area in front of the gate through the creation of the basalt-paved area, saw a radical transformation of this zone. Monument D85 was built with its exterior in opus reticulatum and tufa brick quoining and the interior in opus vittatum and a cross vault ceiling. The columbarium D59 abutting the fortifications and the small mausoleum MSL46312 also date to this phase. The latter was originally destined to house one or more a bauletto burials but was then gradually taken over by a series of burials in tufa brick coffins.

Over the last few years excavations have examined the monuments situated at the crossroads between the road leading west and the north-south road, in particular along the latter’s western edge. The excavations exposed a series of funerary monuments mainly of the “house-tomb” type (A41, A40 and A55) destined to house burials in formae. The tombs now visible all date to the final construction phase of the necropolis, which occurred just after the construction of the via Domitiana and the monumentalisation of the area in front of the gate. The excavations also documented the presence of a series of buildings below the funerary structures.

A third intervention concentrated on an area situated along the eastern edge of the north-south road, at about one hundred metres north of the Porta Meridiana. This year’s intervention completed the excavation of the small dice-shaped monuments exploring the funerary cells and further documenting the stratigraphic sequence through the excavation of a monument dating to the second half of the 2nd century B.C. The mausoleum, a semi-interred chamber with a barrel vault, was built with large blocks of yellow tufa without mortar. The funerary chamber had three cassone shaped beds. The interior was faced with white plaster while the cassoni were painted to represent marble. A stele representing a female individual rested on the summit blocks of the facade.
