The Late Iron Age (fourth–first centuries BC) district of Carpetania in the Central Iberian Peninsula is traditionally cast as a marginal territory, where cultural development is primarily attributed to acculturation, diffusionism and imitation. Here, the authors critically re-evaluate published evidence from the site of El Cerrón, Illescas, focusing on a decorated terracotta relief with a ‘Mediterraneanising’ style to argue that the local elite was not a passive actor in history. Instead, the community at El Cerrón actively engaged in the cultural dynamics that shaped not only the Iberian Peninsula but also the wider Mediterranean basin during this crucial period.

The phenomenon of Iron Age vitrified ramparts has become increasingly recognisable in the last twenty years in the Iberian Peninsula. After the first walls with vitrified stones were discovered in southern Portugal, there have been several findings scattered throughout western Iberia. A chronological sequence from the Late Bronze Age to the Late Iron Age can be established on the basis of the archaeological remains, with reference to different historical and functional conditions. This article reviews the data obtained from the various sites, in order to understand the context in which the stone structures became vitrified. Furthermore, we have analysed samples of stones and mud bricks that have been altered by fire from these sites, which has allowed us to explain the variability in the archaeological record in relation to different historical processes. With all these data, we aim to contribute to our knowledge of a phenomenon that is widespread in Iron Age Europe.
