The museum at the Villa Loupian site was built at a cost of €2.3 million. It was the product of local initiative that brought together elected officials and a team of researchers, with support from the Regional Cultural Affairs Directorate and assemblies at both département and regional levels. It opened in 2000 and welcomes 18,000 visitors annually, thanks to a location in one of the most intensive tourist areas in the south of France, as well as its school outreach policy.
In 2003, management of the site was transferred to the Communauté de Communes du Nord du Bassin de Thau. Since then, the running of the museum, under director Sélim Benalioua, is the responsibility of the Communauté's Heritage and Archaeology Bureau, led by Katia Turrel. Its many missions include the organisation of events for the general public (Les Augustales, Roman-themed days). With the approval of the Minister of Culture and Communication in 2006, rescue archaeology sites entrusted to Ronan Bourgaut offer opportunities for development.
After ten years of activity, ties with the Regional Cultural Affairs Directorate are still critical for the structure. Iouri Bermond (Regional Archaeology Department) schedules archaeology and rescue archaeology projects, and conferences are held in partnership with the Unité Mixte de Recherche 5140 Archéologie des Sociétés Méditerranéennes (Lattes-Montpellier).
