The Opus Siliceum and the Villa Rustica of Alvito: A Treasure from the Late Republican Age
The archaeological site located in the territory of Alvito offers an extraordinary testimony to Roman engineering and agrarian organisation between the 2nd and 1st centuries BC. At the centre of interest is an imposing artefact made of opus siliceum, an archaic masonry technique involving the use of large polygonal stone blocks, carefully laid dry without the use of binders.
The Structure: Terrace or Temple?
The artefact originally served as terracing for a rustic Roman villa (technically called basis villae). The polygonal retaining wall was a necessary architectural solution to regularise the sloping ground and create a stable platform for the building above.
Although the prevailing identification is that of a villa, there is an open debate among scholars: according to some interpretations, the majesty of the structure might not refer to an agricultural residence, but to a temple.
The Geographical and Historical Context: Pescarola and the Alvito Plain
The settlement is strategically located a few hundred metres from the Pre-Roman sanctuary of Pescarola. The choice of the site was not accidental: it is located on the edge of the plain of Alvito, an area that was systematically exploited for agricultural purposes from the earliest days of the Roman occupation of the territory, which took place in the 3rd century BC.
The Evolution of the Villa Rustica: From Farm to Shopping Centre
The function and size of these structures changed dramatically as Rome's influence expanded:
-
Origins: Initially, the rustic villa represented the nucleus of a’family-run farm. At this stage, production was limited to the mere sustenance of the owners.
-
Expansion: With the growth of Roman power and the massive influx of slaves, these units became real commercial companies.
-
Dimensions: The villas reached an average size of about 200 hectares, becoming capable of exporting and marketing their products in ever larger geographical areas.
Roman Farm Architecture and Production
The architectural typology of the rustic villa was strictly functional and provided for a clear distinction between spaces:
-
Residential Part: Destined to the owner or farmer (vilicus).
-
Productive Part: An operational area equipped with stables, wagon sheds and cellars for storing products.
-
Servile Zone: Environments intended to house servants and slave labour.
Crop Diversification
This villa model was particularly widespread in the late Republic and Empire, characterising the landscape of the’Central Italy, from Campania to Etruria. Production was varied and intensive, aimed at maximising the yield of the land:
-
Plantations: Mainly olive groves and vineyards.
-
Cereals: The basis of Roman diet and trade.
-
Other: Intensive cultivation, specialised gardens and pasture areas.
