The Itálica amphitheater, Santiponce (Seville, Spain), has been the most emblematic figure of the ruins of the Roman city founded by Escipión in the context of the Second Punic War, in 206 BC, becoming also the most representative figure of the Itálica Archaeological Complex at present, although it has not been the most studiedbuilding. In this way, a new recent investigation has been carried out with novel results on its new restitution that we present in these lines, contributing mainly to the architecture of the remains that have disappeared today, thanks to historical, historiographical and archaeological research work, in which we will determine the existence of an intermediate structure between the caveas that we have denominated intermediate body.
