In trench H, the area west of the facade of the medieval church, revealing a small terracotta channel overlying burials in earth graves. The excavation of the foundation of the facade wall was completed, and the construction technique was seen to be the same as that used for the east wall. As regards the Roman period, the excavations uncovered a mosaic floor in room 13.

The excavation of trench H-W involved two extensions to the north and south of areas investigated in 2016-2017. On the south front, the perimeters of rooms 15 and 20 were completely defined and a new room situated to the east, denominated room 21, was identified. The area investigated towards the north gave a more complete picture of room 8; however, the north side has yet to be reached.

Following the removal of the early medieval and Roman levels, in trench N-T part of an Etruscan building excavated in 2016 was revealed. It had foundations of tufa blocks similar in proportions and construction technique to those of temple C, but on a different alignment.
In trench R, the tepidarium of the Hadrianic bath complex was uncovered. In the second half of the 4th century A.D., shortly before the complex was abandoned, it was converted into a caldarium.

In the south area, a second circular kiln, smaller than the first, was identified. The two kilns, in addition to having the same morphology were also on the same alignment, with the mouth facing north-south and opening to the north.
