The Invisible Memories project aims to prevent and present alternatives to the radicalization of young people in vulnerable situations from suburbian, rural, and urban areas through the recovery of the historical memory of their local communities in a unique exchange with 30 young people from countries in Eastern and Western Europe. The goal of working with young people is to promote empathy and respect for intercultural differences, reflection on historical memory processes, and community development that helps to generate safe, respectful, and healthy spaces. Throughout the exchange, the three central axes of the project—historical memory (1), creativity, art, and non-formal education (2), and rural and urban environments in vulnerable situations (3)—form the backbone of the daily activities that train the participating young people. At all times, the design of these axes aims to offer tools and spaces for reflection, which can serve as "life-saving experiences" to protect these young people from potential radicalization in their surroundings. At the same time, the project offers the possibility of artistic training to people from disadvantaged contexts, both rural and urban, where access to culture is limited, thus enriching and increasing the range of personal and professional possibilities in the future. The project will involve local and external entities and organizations, such as the Amical de Mauthausen and the Rutas al Exilio, which are committed to disseminating and preserving historical memory among young people. These entities will not only complete the course activities but also serve as a source of inspiration and guidance for the young participants. The project will culminate with the co-creation of an artistic piece based on the different tools and artistic languages explored during the exchange, depending on the core interests that these young people may have. This process will reflect and enhance the individual and collective creativity acquired during the course, encouraging teamwork, collaboration, and constructive dialogue between participants. On the last day, we will open the different artistic pieces we created and share them with the local community. This way, we will provide a unique opportunity that will foster cultural enrichment and social cohesion. In short, Invisible Memories seeks to offer young people from Eastern and Western Europe an experience that evokes the living memories of those who have preceded us and gives voice to the silenced stories that shape our present through theater and the arts in a safe, healthy, and respectful environment. We want to spark the curiosity of participants about their own history and the history of their territories, while providing them with artistic tools through which to share and give voice to them, fostering an understanding of our past as a way of preventing future radicalization of the discourses of these young people. The creation of promotional content, as well as its dissemination through support networks among young people, will be critical elements in ensuring the sustainability and expansion of the impact beyond the project's immediate boundaries.
