Gli scavi alla Terramara di Pragatto (BO): dai primi dati al progetto di ricerca

The work aims to present the first results of the excavation conducted at the Terramara of Pragatto and illustrate the related research project. The area under investigation encompassed a wide strip of about 7,000 square meters corresponding to the southern portion of the settlement. The explorations, conducted by the Archeosistemi AR/S Cooperative, began in May 2016 and are currently being finalized. Excavation reached the settlement’s limits toward both east and west. In the western area, the archaeological stratigraphy resulted progressively decreasing and the presence of a natural slope suggested the existence, already in the Bronze Age, of a watercourse coinciding with the present-day Rio Carpineta. A more complex and articulated system of perimetric delimitation was instead defined in the eastern side, which included a moat, the edges of the embankment’s colluvium, and traces of a palisade and wooden gabions towards the inhabited area. Both structures, the palisade and the gabions, present a gap in correspondence with what could be interpreted as one of the accesses to the village and, although preserved only at the basal level, they appear strictly comparable with those discovered by Pigorini at Castione Marchesi. For what concerns the stratigraphy of the settlement, the materials collected on the surface after that agricultural works have removed the upper levels of the archaeological deposit, date the last occupation to the recent phases of the Bronze Age. The underneath deposit is fully preserved starting from levels dating to the Middle Bronze Age 3 – early Late Bronze Age and it has two distinct phases of well-characterized and regularly spaced heaped dumps. The basal level revealed the existence of a first settlement phase which, in the explored area, seems having included no dwellings, while long palisades delimitating empty areas, as well as holes and stumps, have instead been found. In parallel with the beginning of the excavations, a team was set up to address the research questions related to the geoarchaeological, palaeobotanical, palynological, and zooarchaeological data, as well as to explore potential analyses of metals, objects in animal hard tissues, and macro-lithic tools. The constitution of this team aimed not only at conducting laboratory analyses but also at supporting archaeologists during field investigations. Therefore, in addition to defining proactive protocols for the correct sampling and treatment of artifacts and samples, targeted interventions have been carried out during excavations in response of specific needs emerged during the progress of exploration.
