The work "The Past in His Place. Archaeological heritage, development and tourism” collects contributions from the Third Debate Days of the Museum of Prehistory of Valencia (Spain). The main objective of the conferences was to reflect on the possibilities offered by sustainable tourism management of the archaeological heritage and its impact on the territory. It is intended to reflect on the extent to which heritage projects can find in tourism a way of preserving and profiting culturally, socially and economically and the role of each of the actors in this system of relations.
