Archaeological Area of Poggio del Molino

The Archaeological Area of Poggio del Molino is an archaeological site in Piombino, Province of Livorno, Italy, situated on a headland that separates the beach of Rimigliano to the north from the Gulf of Baratti to the south. The site occupies a plateau approximately 20 metres above sea level with commanding views westward across the sea between San Vincenzo and Elba, and eastward toward the metalliferous hills and the Campiglia lagoon plains. Its significance lies in the remarkably continuous sequence of human occupation, from Paleolithic stone tools through a Bronze Age village and necropolis, to an extensive Roman settlement that evolved from an industrial and defensive complex into a luxury villa, and finally into a refuge during the early medieval period. The site provides exceptional evidence for the economic and social transformation of coastal Etruria across more than two millennia.

The name Poggio del Molino derives from a mill associated with Torre Nuova, a coastal defence and lookout tower built in the early sixteenth century by Cosimo I de' Medici on the slopes of the promontory, as documented in the sixteenth-century 'Bandita di Porto Baratti' and archival sources. Systematic archaeological research began only in the early 1970s, when volunteers from the Archaeological Association of Piombino conducted the first surveys, clarifying the site's dimensions and documenting repeated looting. Between 1984 and 1988, Professor Vincenzo Saladino led a team from the University of Florence in the first systematic excavation of the villa. Excavations have continued since, revealing the site's complex stratigraphy and multiple phases of occupation and transformation.

The archaeological record at Poggio del Molino encompasses material spanning from the Middle and Upper Paleolithic through the Bronze Age, the Roman Republican and Imperial periods, Late Antiquity, and the early medieval era. The Roman phases are particularly well represented, with evidence for iron metallurgy, fish processing and garum production, and eventually luxury residential architecture. The finds include stone tools, globular and biconical urns from a proto-Villanovan necropolis, black slip pottery, a silver coin of Calpurnius Piso, African terra sigillata, kitchenware, oil lamps, wall paintings, floor mosaics, and architectural elements of baths and hydraulic installations. The site's collection is not a museum assemblage but rather an in situ archaeological deposit, with artefacts contextualised within their stratigraphic and architectural settings.

Among the most significant discoveries are the remains of a Late Bronze Age village and associated necropolis, from which approximately fifty globular or biconical urns of proto-Villanovan type were recovered. The Roman period has yielded substantial metallurgical deposits, including sequences of layers rich in hematite, coal, ore, iron slag, and burned clay floors, dated by black slip pottery and a silver coin of Calpurnius Piso to the 1st century BCE. The later Roman luxury villa, constructed at the end of the 2nd century CE, features residential rooms with wall paintings and floor mosaics, including two cubicula separated by a triclinium interpreted as hospitalia. The bath complex includes a tepidarium and caldarium, also decorated with paintings and mosaics, supplied by a raised tank fed by a well probably connected to a wheel-operated system. A belvedere corridor with basins and fountains joined the baths to the residential quarters along the escarpment overlooking the sea. Rectangular basins with hydraulic mortar (cocciopesto) interpreted as cetariae for fish salting and garum production represent important evidence for Mediterranean-wide food processing practices.

The archaeological structures are distributed across the northern and eastern slopes of the promontory, with the Roman buildings situated on a high plateau. The earliest Roman phase was defined by a massive stone and mortar wall enclosing an almost square area, at least partially used as an iron smelting workshop. This defensive-industrial complex was later transformed into a luxury villa, with a large open court perhaps garden with peristyle, around which the residential and bath quarters were arranged. The villa's belvedere exploited the dramatic coastal position. In the 4th century, impoverished reoccupation saw crude structures erected over the collapsed baths and ruined hospitalia. By the 7th century, the ruins provided shelter for isolated pastoralist groups and refugees during the Longobard conquest. The summit of the hill is occupied by the Villa del Barone, built in 1923 by Baron Luigi De Stefano and Assunta Vanni Desideri, daughter of Count Eugenio Vanni Desideri, which overlays and partially disturbs the earlier archaeological remains.

The Archaeological Area of Poggio del Molino is located on the northern border of Piombino's administrative territory in the Province of Livorno, Tuscany, Italy. The site lies on the watershed between Rimigliano beach and the Gulf of Baratti, accessible from the coastal area between San Vincenzo and Elba. The property includes the plateau with its Roman remains and the Villa del Barone on the hilltop. As an active excavation site with ongoing research, access conditions and visiting arrangements are subject to the protocols of Italian archaeological heritage management. The area falls within the jurisdiction of the city of Piombino and represents an important component of the region's archaeological tourism and research infrastructure, complementing the better-known Etruscan and Roman sites of the Gulf of Baratti and Populonia area.
