The project “Anamorphose. Le patrimoine sous le territoire, le territoire sous le patrimoine” continues the pioneering work carried out in historical ecology within the UMR EdySan to question the heritage through its traces and to reflect on the consequences, in the present environment, of certain heritages. Far from starting with an a priori definition of “heritage”, “Anamorphosis” project invites a change of reference : the aim is to bring together academic studies devoted by various disciplines to the processes of building, restoring or conserving heritages and to study the articulation between the definition of heritage and the definition or representation of territories. “Anamorphosis” will host operations to apprehend and restore heritage that is little or difficult to see, or even heritage that has been rendered invisible.
