ARCHEST project aims at connecting four ancient Roman towns in Italy, Slovenia and Serbia: Aquileia, Emona (Ljubljana) Sirmium (Sremska Mitrovica) and Viminacium (Kostolac). During the Roman Empire, a route linked Aquileia to the Black Sea through Emona, Sirmium and Viminacium. These four archaeological sites will work together for promoting the route and developing archaeological audience. The project is composed of three sections: we start with a historiographic analysis of the sites that will be used for 3D reconstructions aimed at developing archaeological audiences. In fact, it is fundamental to use ICT technologies for sites characterised by the lack of easily understandable remains. All the 3D outputs will be made available for free on the project website, social network, app stores and YouTube channel. They will also uplodaded on the tablets used for guided tours that will change the attitude people have towards archaeology and history, being considered something boring or only for educated people.The second section is centred on ARCHAEOBUS, a touring event gathering archaeologists and journalists from Italy, Slovenia and Serbia. They will travel along the route and it will represent a great opportunity for networking, exchange of best practices and sharing of know-how. Journalists will learn more about the route and archaeology and will disseminate information on the sites in the most important reviews. The third part is ARCHAEOPENDAY. Each partner will organise a 2-days event/fair/workshop involving archaeologists and professionals in archaeology-related sectors. Students and general public will take part to these event. Workshops on how to internationalise and strengthen the sectors will be organised.
