Area 8300 is situated in a vast architectural complex that extends to the north of the Basilica of Bisarcio and which is now a large fortified courtyard. A complex sequence of construction site activity and fills in the area dating from the late 17th century until the mid 19th century covered an occupation phase that the material finds show was of a very different date to the preceding one. In fact, two layers were identified that obliterated a construction site phase, which however no longer related to the demolition of structures but the construction or restoration of the fortified curtain wall. The pottery provided a terminus post quem of the late 14th century.

This evidence consisted of traces of the scaffolding used during 14th-century restoration, which stood directly on the levels of a domestic midden. The latter contained numerous layers of ash within which there were abundant food remains. Below the midden there was a phase relating to the filling of the area. When the porticoed space had gone completely out of use, the area, where by this time the fortified structure was being built, was used as a rubbish dump, mainly of ash and charcoal, evidence of the builders’ intense work on the site at the end of the 14th century.

The excavations in area 5100 provided new data regarding the stratified deposit situated east of the enclosure surrounding the monumental basilica of Bisarcio, close to the north side of the cathedral.

Thus far, stratigraphic contexts dating to between the first millennium B.C. and the first decades of the 21st century have been identified.
An imposing wall was uncovered in correspondence with a large deep hole dug in the 17th century, which cut it. The excavation of the fill was completed during this campaign. An area used as a midden for domestic waste was identified, which contained abundant faunal remains and cooking vessels with a low amount of fragmentation and sporadic wall sherds from transport containers. Based on a preliminary analysis, this activity dates to the Iron Age.
An extension of the excavations in the western part of the sector produced evidence that provided a better understanding of another structure pre-dating the creation of the medieval cemetery of Bisarcio.

In an adjacent area, traces of iron working were identified, attested by the presence of abundant iron slag mixed with ash and charcoal found in situ. In the absence of ceramic finds, the presence of a coin minted by the Republic of Genoa (1138-1339) could date this activity to the medieval period.

During this campaign, the complete sequence for the late medieval cemetery, situated in the western part of the area, was documented with the discovery of two more burials.
