The operation concerns the historical site of the caves of Saint-Christophe-la-Grotto, a geological, natural and prehistoric heritage, where a variety of cultural and tourist activities are offered, free and paid, accessible year-round for some and from March to November for others (linked directly to the visit of the caves). The Commune of Saint Christophe has decided to carry out a global operation in order to requalify the site based on a better knowledge and a reinforced valorization of the natural and historical characteristics of the site. For this, two phases of studies and work have been defined. The ERDF supports the second phase, which consists of improving the customer experience (quality of reception, services, information and signage) and updating the interpretation offer associated with these heritage assets.
