Around the Hannibal’s Wall: apprehending a “tactical mapping” of the first century BC in the Poenines Alps (Valais, Switzerland and Aosta Valley, Italy)

Sites occupied by Roman soldiers during the second half of first century BC have been found between 2300 and 3100 m altitude in the Poenine Alps. After an introduction to the research program on these positions, a catalog presents the results of the investigations on the Valais sites. The confrontation of these discoveries with historical sources and, more particularly, with the events that led to the establishment of Roman hegemony over this region, as well as the reminder of the methodological reservations inherent to this exercise, serve as a conclusion. All this cast a new light over the late-republican period in this part of the Alps and presents a state of this ongoing research.
