Between 1985 and 1990, excavations in the locality of Poggiarello Renzetti uncovered a new atrium house (with structural analogies to coeval Pompeian houses such as the _ Domus Stalli Erotis_, the House of Parnassus) of the type known from the Falchi excavations 1895-1896. The occupation phases dated to between the beginning of the 2nd and mid 1st centuries B.C. when the structure was abandoned, probably due to a fire. A fragment from a figured architectural plaque was discovered below the atrium roof collapse. It was part of the series already found in the same place by Falchi and generally ascribed to the decoration of a _naiskos_, a find showing that these plaques were also used in private structures. The plaques have also suggested a new mythological interpretation of the figures (Medea at Corinth). The vivacity of commercial exchange in this period was documented by the presence among the finds of Rhodian amphorae, Spanish pottery, and Sardinian-Punic coins, not previously known at Vetulonia.

The 2017 campaign concentrated on the front part of the residential structure denominated _Domus_ _dei_ _Dolia_ situated in the centre of the Etrusco-Roman urban quarter partially excavated by Isidoro Falchi in the late 1800s in the locality of Poggiarello Renzetti. The rear part of the structure was built up against the hill and therefore a substantial part of the walls was preserved. However, the front of the _domus_ is on a flat area later used for agricultural purposes and has been badly damaged by the construction of a terrace wall that has “cut” the entire house in two, and by ploughing and the creation of an olive grove. The excavations investigated three crucial points in the front part of the building. These were constituted, from east to west, by the continuation of the paved road that emerged between the _Domus_ _dei_ _Dolia_ and the adjacent _Domus_ “with cistern”, the arrangement of rooms along the facade and the alignment of the latter’s perimeter, the identification of which was important for finding the entrance to the house and the basalt road onto which it faced. In the first area (area O), the excavations uncovered the original make-up for the basalt road to the east of the house and the original drainage channels on either side of it. The investigation here further clarified the chronological relationship between the creation of the road and its channels, and the cut made on the paved surface for the creation of a deep drainage channel along the perimeter wall of the _domus_. The materials recovered during the excavation of the channel’s east parapet provided a useful _terminus_ _post_ _quem_ for the construction of the channel and of the _domus_, in what appears to be is definitive monumental layout, sometime after the end of the 4th century B.C. In the second area (area P), situated in the eastern part of the house front, the excavations revealed the presence of a new room delimited to the south-west by walls forming a right angle, on the same alignment as the walls forming the sequence of rooms along the rear of the _domus_, representing the final occupation phase. The remains of an _opus_ _signinum_ floor emerged in the room in area P, in which there were two Roman asses of the prow series and a silver fourrée with the head of _Juno_ _Sospita on the obverse and a bull and the legend attributing its emission to the _triumvir _ _monetalis_ _Lucius_ _Thorius_ _Balbus_ on the reverse. This provides a date within the first decades of the 1st century B.C. that is coherent with that of the probable destruction of the _domus_ and the entire residential quarter of Poggiarello Renzetti in the Sullan period as part of the reprisals undertaken by the Roman consul following his victory over Marius and his allies. In the third area (area Q) the excavation concentrated on identifying the north perimeter wall of the _domus_. The wall was found a short distance from the new room in area P. The basalt road denominated Via dei Ciclopi must have run north of this wall and parted at a right angle from the Via decumana to run parallel to the Via Ripida in the direction of the basalt road between the _Domus_ _dei_ _Dolia_ and the _Domus_ “with cistern”. Together these roads formed the urban grid within which the Hellenistic residential quarters of Poggiarello Renzetti were situated.

Following the line of investigation dictated by the results of the 2017 excavations, the 2018 campaign focused on the northern half of the residential structure known as the _Domus_ _dei_ _Dolia_. The structure is situated in the locality of Poggiarello Renzetti within the Etrusco-Roman urban quarter excavated in the late 1800s, and dated by Falchi to between the early 3rd century and first decades of the 1st century B.C. In 2018, the excavations concentrated on the northern part of the structure, in particular the front along the continuation of the so-called via dei Ciclopi and the north-eastern and north-western sectors, primarily continuing the investigation of the three crucial areas identified during the previous season: area O (on the same axis as the basalt road Us 3 to the north-east), P (the new room identified in the northern part in 2017), and Q (adjacent to area P and corresponding with the façade of the _domus_ facing onto via dei Ciclopi. At the same time, trench I was extended to the west of area O and north of room B, and in the new area K (in the north-western corner of the _domus_). Proceeding from east to west, the removal of the spoil heap from area O revealed new portions of the original paving of the road US 3 – and a section of the associated drainage channel – in the northern stretch of its continuation in the direction of via dei Ciclopi, to which it must have joined at a right angle, forming the north-eastern corner of the _insula_ between the so-called via Ripida and the via dei Ciclopi, entirely occupied by the large _Domus_ _dei_ _Dolia_. In the overall layout of the quarter, the latter assumes the physiognomy of an imposing corner construction. Another short stretch of road may have branched-off from basalt road US 3 at a right angle, as suggested by a small concentration of medium to large stones arranged to form a surface (US 299) uncovered in the new trench I (adjacent to area O). The latter can be interpreted as one of the entrances to the _domus_, which was also directly accessible from the road US 3. The opening of trench I, adjacent to area O, led to the identification in the northern part of the continuation towards the east of wall US 215, which closed room P (partially investigated in 2017) to the south, and revealed almost completely revealed the room’s plan. Further exploration in this room uncovered important structures. Firstly, the _in_ _situ_ continuation of wall US 235, which delimited room P to the north and at the same time formed the north side of the house, the stone threshold US 281 which, flanked by a stone semi-circular base (of a column?) US 282, seemed to represent the main entrance to the _domus_ from the via dei Ciclopi. The entrance appeared to remain the main entrance to the _domus_ until the end of its use, as seems to be indicated by the discovery still _in_ _situ_ close to the threshold of the iron fixings from the original door (probably timber) and, immediately outside the threshold, of a silver plated coin bearing the name Caius Licinius Macer on the reverse indicating 84 B.C. as the possible date of issue. This chronology would be coherent with that of the final phase of the house, attributed to the years dominated by the military reprisals carried out by the armies of the Sullan faction. Significant and unexpected results, due to the badly compromised condition of the structures, came from the new trench K opened in the north-western part of the _domus_. Adjacent to room P, area K appeared to be a quadrangular space closed to the north by the house’s northern perimeter wall parallel to via dei Ciclopi. The centre of the space was occupied by a sub-rectangular structure (only partially excavated), which suggests this was possibly a space with an _impluvium_ similar to a peristyle.
