Achievements: The Hungarian–Serbian border region shares a common culture and heritage. This project explores the potential for cooperation which the common heritage offers. The Thorma Museum in Kiskunhalas and the Municipal Museum in Subotica jointly promoted the necessity of common heritage management through a variety of well-targeted events, well-attended exhibitions and informative and interesting promotional materials. The project partner institutions, two museums located on each side of the border, realised that common responsibility for shared natural and cultural values as well as traditions can be a solid foundation for the development of tourism in the region. The partners organised an exhibition of architectural and cultural heritage of the towns in the plain – The Cultural Treasures of the Kiskunhalas District and North Bačka. They edited and distributed a well-researched and interesting exhibition catalogue in four languages for various local and international audiences and visitors. In this project, the younger generation and children also had the opportunity to learn about common heritage. The two museums coupled the exhibition with interesting educational and fun activities, for example Game Days for nursery children and schoolchildren. From this material they also arranged joint travelling exhibitions in Hungary and Serbia. The projects enduring result is the cultural thematic route of architectural heritage from Pirtó to Kelebia. They also held a successful conference about Art Nouveau in Subotica, organised lectures about the exhibitions and the thematic route, workshops with the representatives of touristic and cultural organisations. The cross-border project partners found a viable and sustainable way of coupling the regular museum activities, preservation of shared cultural and architectural heritage, with improvement of the touristic attraction of the region. They collected information about interesting and important sites, compiled it into an interesting educational and promotional message, and attracted tourist with it. By highlighting the cultural values the project contributed to increasing income from tourism in the border area.
