Created in 1991, CReAAH is an interdisciplinary research unit at the intersection of social sciences, environmental sciences and physical and chemical sciences. Under the supervision of the French National Centre for Scientific Research (CNRS), the universities of Rennes 1, Rennes 2, Nantes and Le Mans, the French Ministry of Culture, and with the French National Institute for Preventive Archaeological Research (INRAP) as a partner institution, CReAAH is characterized by its structuring and unifying position in a large north-western quarter of France. Its field of activity revolves around the study of changes in human societies over the very long term, from ancient prehistory to the early modern period, and covers a very broad geographical area. For France, this mostly involves the Atlantic Coast. CReAAH holds a prominent position in the national archaeological and archaeological sciences research landscape.

The Methodological research platform is a place for formulating ideas in the fields of experimentation, setting up repositories and databases, development, application and optimization of analytical methods, and modeling.
In terms of international cooperation, major research programs are being developed in Europe, North and South America, Middle East, Asia and Africa.
