The assessment of the important changes that occurred in late third and second millennia societies across Europe often emphasizes changes in technology and the emergence of associated objects and art forms, changes in burial rites, and developments in economic practices. Notions relating to the evolution of homo economicus dominate many of the discourses, and the evidence for increased long-distance trade / contact across Europe is used to bolster this assessment. These themes are underpinned by an obsession with ever-refined chrono-typological phases. In an attempt to present a more socially embedded perspective, this paper considers the changes that occurred in the uses of the high-altitude, sub-alpine, and alpine zones in the southern French Alps during the third and second millennia BC. From c. 2500 BC onwards, there was a fundamental change in the use of and engagement with this landscape. The first substantial stone-built pastoral structures at high altitude (2000 m and above), appear at this time. This departure in the use and structuring of the alpine space would have included concomitant changes in the nature of mobility, notions of territory, and memories associated with this area.
