The paper, published in the Journal of Roman Archaeology 33 (2020), discusses the most important results of Duke’s new fieldwork project at Renieblas, set up in 2015 by Prof. Alicia Jiménez. It reviews the excavations of four sectors of Camps I, II and III between 2015 and 2017, the study of artifacts in archaeological context, radiocarbon dates, faunal and viewshed analyses, as well as the topographic and archaeological surveys conducted by our team in 2018 and 2019. The long term goals of the project include an analysis the rôle of the army in the creation of the earliest provinces, the complex supply-system to Rome’s first campaigns abroad, and living conditions in the camps.
