The "Institute for the Danube Region and Middle Europe" (idm.at) (Austria) discovered that the people in countries in the Danube Region, especially eastward, do not know much about the cultures of their neighbours, and their young people seem generally not interested to travel to visit each other – in contrast to their dedicated wish to visit the more “Western” countries. To start to change this, we decided to invite young people, "teens", to start early before prejudices develop. We created the idea to organize “International Danube-Camps” to connect the teens from these countries to become more curious about the cultures of their “neighbours”, not "contaminated" with prejudices and generally more relaxed toward other countries. Danube-Camp's aim is to decrease the threshold to enter communication between cultures, nations, and regions, so that it becomes easier to get in touch with each other. It’s about doing the first steps to even get to know each other and then to learn whatever there is to learn on an individual base, comprehending that though those people speak different languages, wear other clothes, or eat strange meals, they are in essence not so much different to the people at home. As it is already often complicated to WORK with people (and not just talk) you know in a culture you are familiar with, it is just natural to expect even more troubles when working with people from other countries. Still, we want to encourage our teens not to be scared by anything unexpected or difficult, and to find solutions to overcome these situations, broaden the horizon and get - or stay – open minded. And we realized in the end that it was not only worth the effort but also a rewarding experience during the first Danube-Camp 2019 in Tulln, Austria. Besides the actual activities, the "Danube-Camp" wants to show that youth workers, teachers or teens themselves have all they need on their hands to start working on exchanging with other coun-tries or cultures almost immediately. >FIRST INTERNATIONAL DANUBE-CAMP 2019: To gain practical experiences, a first "International Danube-Camp" as a sort of pilot project was organised in Tulln, about 60 km from Vienna, with teens from 4 different cultures: Austria, Bulgaria, Hungary, Serbia, aged 13 to 14 years: They were able to speak some English, handle smart phones, and could develop new paradigms and attitudes - and were curious and motivated to find new friends. The teens at this Danube-Camps worked in GROUPS of 6 teens from 2 TEAMS from different countries on 31 mostly culturally relevant “MISSIONS” and activities e.g., showing how to cook typical meals, exchanging experiences of results, discovering the envi-ronment, interview each other about their situation in school, showing how festivities (e.g., marriage) are performed, but also learning how to program together a robot or how to design a piece for the 3D-printer. We issued daily newsletters, here their link: https://drive.google.com/drive/folders/16WH24Wg0IExnm3hyKrOpkilIzcxWzZlF?usp=sharing To enhance the communication between the teens from different countries, the following structure was applied: A "TEAM" of 3 teens from one country is formed to stay together for the whole Danube-Camp. Two of these "TEAMS" from different countries form a "GROUPS" (of 6 teens); every day different combination of TEAMS! This way, the teens did not only "play" and "talk" with each other but learn to WORK together to fulfil the tasks of the daily one or two MISSIONS. An anonymous survey showed that all participating teens wish that this structure continues. The survey also showed that all teens would like to participate again in a Danube-Camp - and that all made more than 3 friends from another country. >NOW: SECOND INTERNATIONAL DANUBE-CAMP 2020/2021. The 2nd version of the International Danube-Camp took place in Viminacium, a Roman excavation site, about 90 km East of Belgrade. One idea was to work out how to transfer the knowledge from the 1st Danube-Camp to another organisation, including improvements from what we learned. Five Participating countries: Austria, Bulgaria, Romania, Serbia, and the Ukraine. There are several reasons, why we applied in Austria for a "Danube-Camp" in Serbia: 1. This would start a process of transferring this knowledge to another country. This should test, how Danube-Camps could be continued more or less from organisations in other countries by themselves. 2. All organisations which participated in the first Danube-Camp wanted that the Serbian partner takes over for the 2nd version of the Danube-Camp, but under the main guidance and coordination of "International Cultural Communication." 3. ERASMUS+ is very new in Serbia, with currently very few funds. 4. The new location is more central to the Eastern part of the Danube-Region with on average less travel costs.
