The proposed action involves intensified cultural and educational interaction through close cooperation of students and teachers of the Polytechnic School in Subotica and the Vedres Istvan School of Architecture in Szeged that have similar fields of activities in the area of education and architecture. Project activities such as the joint development of a course programme History of Architecture – regional heritage that involves study visits, students' and teachers' exchange programmes as well as the participation of the wider professional public contribute to the overall aim of the Programme, that is the development of a harmonic and cooperating region with a sustainable and safe environment, successfully managing the common cultural heritage. The project will take place in Szeged and Subotica cities, at the participating schools' premisses and at public buildings of significance from the point of view of common cultural heritage. Students, teachers and professionals will explore the parallels of the development of the two cities together – mainly from architectural point of view, not considering them as two separate entities but as two elements of the same puzzle, the very same region. We expect to achieve strengthened cooperation between the project parters, new contacts and cooperation among educational and cultural institutions in the region as well as improved interpersonal relationships achieved through jointly developed course material, jointly developed historical study paths of both cities to be published on a map, jointly developed and implemented modelling course for students, multilingual project events, students' camps, exhibitions with multimedia presentation of the project products (models and handicrafts, photographs, publications, film, blueprints and other material collected or produced), interactive educational software to be made of the materials accumulated. Achievements: The similarities between the architecture of Szeged and Subotica are conspicuous, thus, it is no wonder that the two cities are called twin cities. This resemblance was the base of the cross-border cooperation of the Polytechnic School in Subotica and the Vedres István School of Architecture in Szeged. Within the project the two schools were able to strengthen their educational partnership, students and teachers explored the parallels of the development of these two cities from the middle ages to the Art Nouveau era, not considering them as two separate entities but as two elements of the same architectural puzzle. With this project both schools seized an opportunity to fully realise the dedication to minimizing the ex-catedra teaching method and promote learning through hands-on, proactive and practical engagement of pupils. This has proven to be the ideal way of instilling reverence for cultural heritage in future architects, engineers and builders. The project partnership arranged a very rich and diverse series of programmes in both cities. Firstly, Photo Days in Szeged and Subotica engaged the students in walk-tours during which they had the opportunity to identify the buildings of interest for their study and research. Yet, the proactive and practical approach to study and research did not stop there. The pupils took photos of the architectural heritage. As the two schools adopted an integrated and inclusive approach in (co-)creating teaching tools, the input of the pupils was regarded as a starting point for further work. Thus, on the basis of the pupils’ photographs the teachers and experts in education and architecture developed the teaching materials. During a study week and modelling workshops, the cross-border student teams prepared the model of the Subotica Fort and of the Orthodox Church in Subotica. On the handicraft workshops the pupils improved their skills in working with clay, wood, glass and enamel. As a crowning event a well-visited exhibition was arranged from the works. One of the greatest achievements of the project was the smooth professional cooperation and the established personal contacts among the teachers and students. Pro-active and inclusive approach to teaching architecture through active participation of pupils in the development of the teaching materials, architectural modelling and practising handicrafts increased the awareness of similarities between the twin cities bringing people from both sides of the border closer to each other.
