Point 3. Cerretanian town planning
The Cerretanian oppidum covered an area of about 6,000 square metres, bounded by the strong southern wall and by the steep slopes on the other sides, where the walls of the houses formed the effective boundary. The houses inside were built with two rooms, an anteroom and a main room at the back. They were laid out next to one another in terraced rows.
So far 15 domestic units have been identified, all of them with a rectangular floor plan and around the edge of the settlement. Extrapolating the number of houses according to the relief on the plateau, and placing them in a radial layout, would indicate that there were about forty houses. Bearing in mind that each domestic unit housed 4 or 5 people, this would give an estimated population of between 150 and 200 inhabitants.
The properties are all fairly similar in their structure, and there does not seem to be much detectable variation revealing social or economic differences between them, though those in the southern part are slightly larger than those in the eastern part. A special case is the house just beside the Cerretanian gate, made up of three rooms, where remains and materials have been found which might be related to ritual-type ceremonies.
As regards the central part, this is laid out as a ring of homes around a large square, and there would also have been some features of a communal nature here. The western part would be set aside for a large granary for storing cereals, especially from the 3rd century BC onwards. There must also have been a water tank, pits to catch water and perhaps animal stalls. At the same time, it is also true that the large size of the public square leads one to think that some part of it might have had a small network of streets built on it, with small blocks of homes.
