The Project ARCHEST was designed to improve the presentation of the site and to, consequently, attract new visitors. The main objectives were support- ing the archaeology-related creative sectors to operate transnationally and to increase the knowledge of common Roman history through the most important archaeological sites. Additionally, there was an objective to increase the audience with an integrated approach and modern technology, transforming a non-audience into a new audience and changing the opinion that archaeology is something boring or too elitist. The results of the project have a huge appeal to ordinary audiences and support a better understanding and acceptance of Roman civilization through clear images which, at the same time, do not contradict the scientific concept but, rather, aim to support it. keyWords: 3d reConstruCtIon, VIRTUAL reaLIty, VIMInaCIuM, arCHest.
