Area 8300 is adjacent to Area 7700, a further part of the courtyard investigated between 2014 and 2015 where the excavation revealed a sequence relating to a late construction phase of the rectory, phases that can now be considered to have been fully investigated. The various construction phases and the phases during which the building went out of use and was abandoned have been defined, and date to a period between the first half of the 9th century and at least the second half of the 15th century. At this time, the line of the curtain wall and the remains of the large building were probably very similar to their present appearance and what can still be read in the stratigraphy of the remaining walls. This transformation coincided with a serious political crisis aggravated by the struggle between the Aragonese and the house of the Arborea. So far, five of the site’s six occupation periods have been identified in the area in question.
Area 5100, immediately north of the northern side of the Basilica of Sant’Antioco di Bisarcio, covers a quadrangular area of 100 m2, divided into four squares, Sectors 1, 2, 3, and 4 each 25 m2. The excavations in these sectors were deepened according to the objectives of the various campaigns (fig.13). During the last two seasons, an L-shaped area, sector 5, was opened covering 24 m2 situated along the wall surrounding the bishop’s residence, the western and southern parts of Sector 1. There remains more to investigate in the Period IV cemetery situated below the village of Bisarcio, which probably developed around the apse and along the north side of the church from the 11th-12th century onwards, at the same time as the foundation of the ecclesiastical complex. The excavation of a limited area of this vast cemetery began in 2013, which the diagnostic material has dated to between the first half of the 14th century and the 17th-18th centuries. The cemetery was inserted into the pre-existing landscape constituted by ruined buildings with the distribution of the tombs conforming to the available space. This season the number of burials excavated was substantially increased.

At the end of this season, the excavation in Sector 5 identified a more representative sample of burials for the post-medieval phases. Another part of the pre-existing building was also uncovered on which the wall enclosing the complex was built, although its function and chronology have yet to be defined. During the 2017 campaign, 15 single burials in simple earth graves belonging to 11 juveniles and four adults were identified. They can be dated to the cemetery’s three phases of use. Due to lack of time, only 11 were fully excavated while the other four will be completed next season.
