T-PAS project aims at connecting three ancient Roman towns in Italy, Slovenia and Serbia that is Aquileia, Emona (the ancient Ljubljana) and Viminacium (Kostolac, close to Belgrade). During the Roman Empire, a route linked Aquileia to the Black Sea through Emona and Viminacium. These three archaeological sites will work together for a joint promotion of the route and of the sites along it. This project will lead to the realization of the first concrete foundation of a European Network of Archaeological Sites. The project is composed of three sections: we start with a socio-economic analysis aimed at benchmarking the state-of-the-art and the tourism demand and supply in order to develop innovative transnational approaches for increasing employment and business attractiveness. It will be realised involving the population and bearing in mind AGENDA 21 for Culture. The second part is the promotion of the Roman route: we intend to create tourist packages, work with primary schools organising laboratories and deepen the knowledge of the road. The last section of the project consist in three study visits for cultural operators in each of the archaeological sites concerned. It will foster both the exchange of best practices and the transnational mobility.
