The project „Our Spaces“, which is set up between 6 schools from different countries around the Baltic Sea (DE, EE, FIN, LV, PL, SE) deals with shared spaces in our communities and our schools. We believe that it is a major social responsibility of all citizens to help create well-designed, -maintained, inclusive and safe shared spaces that allow social mixing, civic participation, recreation, and a sense of belonging. Accordingly, we want students to develop concepts for some of these spaces and contribute to making these spaces more attractive for a variety of users and purposes. By exchanging ideas and comparing perceptions with other young people from different countries, diverse ways of designing and using shared spaces can be utilised. There will be two international students meetings (2019: public spaces in the community, 2020 shared spaces at school) and various activities during regular lessons.
