Arqueologia de la arquitectura en el oppidum oretano de El Cerro de las Cabezas focuses on the two bastions that make up the south gate of the Iberian oppidum of Cerro de las Cabezas (Valdepenas, Ciudad Real). It comprises two defensive constructions whose internal space fulfilled a socioeconomic function related to the storage of cereal. Primarily archaeoarchitectural, supported by the digitisation and study of the photographic archive of the excavation, the research aims to analyse the construction techniques and materials of both structures, define their successive construction phases within the historical process of the settlement and to evaluate the architectural ensemble within a spatial area of enormous importance within the urban framework. All this allows us to understand the continuous changes and transformations that this space suffered between the 5th and 3rd centuries BC to defend Punic influence and presence in this Iberian oppidum.
