The last fifteen years have seen in France a rapid increase of Iron-Age archaeological studies, both as part of the development of ‘National Archaeology’ and of political changes. This neo-structural analysis aims to make Iron-Age archaeological studies objective. It underlines how the need for a national identity influences Iron-Age archaeological constructions and strategies. After describing the ‘total’ context of French archaeology, the analysis unveils the symbols underlying Iron-Age studies in France which fit familiar archetypes – including a common ancestor – contained in the collective memory, and enables one to apprehend how the permanence of archetypes may contaminate archaeological constructions, thereby reinforcing the original ideological/archaeological strategy.
