The 2016 campaign in the area next to the complex of Valva concentrated on areas A, C and F, outlined during previous seasons. A second bell-making pit, identified in 2015, was excavated in area A, which contained several fragments of the plaster bell, attesting the use of the lost-wax casting technique. In the western part of the area, a stretch of the road surface delimiting the late antique fortification was investigated. This represented the last time the road surface was raised and comprised a make-up and surface of limestone pieces of various sizes that were laid flat. The road ran north-west/south-east on a straight line. Close to the southern edge of the excavation area, a patch of what must have been the floor of the early medieval palatium was discovered. It had been used in the Romanesque construction site as a surface on which metalworking activities took place. The floor was made of medium sized stone slabs arranged in rows, bedded on a make-up of mortar mixed with earth and ash.

In area C, situated next to the southern perimeter wall of the oratory of S. Alessandro, the excavations investigated a complex stratigraphy below that associated with the Romanesque building site. The finds suggest a chronological horizon between the 7th and 8th century A.D. Several postholes were identified, which at present cannot be related to each other in plan. Among the residual material were lamp fragments and coins dating to the 4th-5th century A.D. relating to the dismantling of a late antique funerary area that must have existed in the area and of which several terracotta fragments from the bottom of burials were found. The most interesting elements found this season came from the continuation of work in area F close to the apse of the church of S. Pelino. A sector of the western perimeter wall belonging to the Roman campus had already been uncovered in 2015. This season, a limekiln was found up against its east wall, robbed in antiquity of its opus reticulatum facing. The material from the fill indicates that the limekiln functioned between the late 11th and early 12th century.

On the opposite side of the wall, towards the west, the foundations of a monumental gate were discovered, which must have linked the area of the late antique fortification to the campus, and through which the road uncovered in previous campaigns crossing the area from north-east to south-west must have run.
