Culturespaces, the company that manages the ancient monuments of Nîmes, is faced with a thorny problem: how to successfully reconcile the cultural and heritage aspect with the leisure aspect in its communication? Culturespaces is obliged to communicate in a conventional way because of the monuments it manages, but it must also respond to a marketing strategy in order to succeed as a commercial and leisure company. It must therefore succeed in integrating the heritage dimension without overdoing it or falling into the "Disneyland" effect. This explosive mix shows us that the greatest seriousness is necessary in the communicative treatment of historical monuments. Finally, we evoke the appeal of "living history" to illustrate this demand for renewal in classical culture through the examples of Caesar's Camp and experimental archaeology. Thus, we wish to show by example how Culturespaces succeeds more or less well in combining culture and leisure, heritage and entertainment, history and games in its communication as well as in its media treatment of historical monuments and the events organized there.
