The Etar Regional Ethnographic Museum (REMO “Etar”) has the status of immovable cultural property of the category “national importance”. Remo “Etar” is the first open-air ethnographic museum in Bulgaria and opened its doors on September 7, 1964. REMO “Etar” is a group tourist site characterised by diversity, uniqueness and authenticity as a result of the individual sites covered by it. This project covers a complex of investment and marketing activities aimed at the development of REMO “Etar”, diversification of the tourist product and its transformation into a living museum, providing the opportunity for exercise of non-seasonal but permanent active cultural tourism. All activities planned in the framework of the project implementation are aimed directly at overcoming the challenges to the sustainable development of REMO “Etar”, related to the need for conservation, conservation and restoration of the sites covered within the museum complex, as well as due to inefficient utilisation of their areas, the lack of modern conditions and equipment for the purpose of diversification of the tourist product, the lack of effective interactive information tools and programs with the potential to attract more and more diverse audiences, the project covers a comprehensive solution, both for the conservation and preservation of REMO “Etar”, as a group tourist site, and for the effective promotion of the museum.
