This season, work took place in two main sectors of the proto-historic settlement of Bostel di Rotzo. The excavations of sector D continued, the only sector where both occupation phases of the plateau are present. The plateau was probably sporadically occupied from the 11th century B.C. onwards and permanently settled from the 6th to the 1st century B.C. The second area of investigation was sector G, identified in 2017 during a campaign of Remote Sensing but only investigated in 2018. In sector D, an additional room was discovered to the north-west of the dwelling present in this sector. The obliteration sequence for this room was very different to that seen in the interior of the dwelling suggesting that it had already gone out of use in antiquity.

The north edge of the structure in the area adjacent to the new room was identified. In this zone the walls were preserved to a height of at least seven stone courses although at present the ancient floor surface has not been reached. Along the south-western side of the sector the excavation continued of a structure built of small overlying slabs of biancone stone, which is difficult to interpret. In fact, the south-western part of the structure was partially compromised. Two large lead ingots were discovered up against the slabs, probably to be associated with a phase when the structure went out of use.

The excavations in sector G were extended and deepened, revealing a structure with two rooms separated by a substantial internal wall. The primary collapse of the walls and a very charcoally matrix were present inside the north room. In contrast, the south room contained few charcoal traces and the obliteration was more homogeneous and uniform, suggesting a rebuild in antiquity that saw the first room go out of use. Among the most interesting finds was an imitation Massalian silver drachma that makes it possible to date the structure to around the 2nd century B.C.
