Open-air museums are professional and scientific institutions that are managing specific plots with the purpose of portraying different ways of settlements, buildings, and the way of life of a certain culture.With innovative solutions based on cooperation regarding business processes, the project tackles common challenges of the program area in the field of development strategies, operational procedures and promotion in the filed of open-air museums. The project also addresses the lack of interlinkage between open-air museums, cultural tourism, and other related activities, with the goal to improve the situation of already existing open-air museums and to identify appropriated measures of newly established museums. The lack of poroper conditions will be addressed through the project’s long-term approach and interdisciplinary cooperation, which will involve various participating stakeholders who will contribute to better capacity building. The main objective is the achievement of higher cooperation levels between both partners and other interested organisations involving the development of a modular long-term strategic partnership. This goal will be achieved through institutional cooperation of both partners and other interested organizations in the field of open-air museums and cultural tourism. Regarding the work area defined within the project, both partners have developed different skills and gathered various experiences.The Hungarian partner is an established administrator of a first-rate open-air museum and the Slovenian partner is currently in the first stages of establishing an open-air museum, thus both PPs will complement each other during project’s development. Moreover, their existing and newly formed networks will increase the potential of achieved results.The project envisions staff exchange activities, staff meetings, meetings involving other stakeholders, educational and promotional tours, experiential workshops, and a published e-reference book.
