The main objective of the project is to develop and validate a group archaeological cultural property (GANCC) “Antic town of Heraclea Sintica with adjoining necropolises” as a competitive tourist attraction on the average currents of Struma River, which contributes to the diversification of the tourist product offered by Petrich Municipality. Planned for two development zones — for Cultural Historical Heritage and for socialisation. Through the implementation of engineering, the main activities under the CRC and the construction works will be implemented. In ZONA 1, all the CRCs will be implemented with the aid of the exposed structures, including: ancient fortress wall, residential district, early Christian necropolis, CGC of the ancient town of Heraclea Syntica — forum and adjoining sites, buildings under the Roman forum, shops and sanctuaries, civil basilica, early Christian basilica, etc. There will be a service center with the ticket desk, a room for tour guides, toilets and warehouses, free parking, infrastructure for providing access for disadvantaged people and connecting an alley between individual archaeological sites. In ZONE 2, a visitor centre with an exhibition and virtual hall for the exhibition of cultural heritage will be built with a grant for free use of children’s aquapark attraction, wide public access area, playgrounds, guarded parking lot. In order to create an integrated tourism product (ITP) with funds from FI, a small-scale income generating investment in a municipal property will be built, where a food and drink area, attraction “Rome Thermi” with swimming pools, accommodation area, children’s camp, camping area will be built. The FI will carry out the activities of promoting the attraction, conducting 3 festivals and information and publicity, auditing, project management (by employees of the municipality). As a result, one ITP for the GANCC will be created, its attractiveness will be increased, the number of visitors will increase. The management and management of the site, after its completion, will be stretched by the Municipality of Petrich.
