A. Depalmas, F. di Gennaro, Dove e come costruire casa nella protostoria delle due sponde del Tirreno

The paper analyzes in diachronic perspective the characteristics and developments of the houses and their forms of aggregation on the Tyrrhenian side of the peninsula and in Sardinia during protohistoric times. In the peninsula, dwellings tended to cluster on the "defended areas", which in the Late Bronze Age prevailed over "open" settlement positions. The Sardinian settlements developed starting from the Middle Bronze Age, frequently close to the Nuragic towers, with the placing of rectangular and then circular structures, forming scattered and disjointed clusters. Even in the Middle Bronze Age 2-3 the process of aggregation of circular and quadrangular structures began according to a scheme that would tend to the centripetal development of housing complexes. In the early Iron Age, when in the continental territory the settlement categories differed according to the hierarchy determined by the rising States, with houses that tended to standardize the shape according to previous experiences, in the island the central courtyard building achieved a precise aspect characterized by a unitary structure of mainly circular shape within which the rooms are arranged radially around the courtyard. Later, but still in the early Iron Age, there was a tendency to disarticulation of the isolates with the presence of a greater number of rooms - especially small ones - not strictly revolving around the courtyard.
