On November 5, 2026, up to 300 young people between the ages of 13 and 17 will once again have the opportunity to spend a morning developing their own projects for Mainz and engaging in conversation with representatives from city politics and the city administration. Whether it’s leisure, school, public transportation, or sports—the teens decide which topics are important to them and what needs to be improved in Mainz. Following the youth conference, the project groups will have one year to implement their ideas. They’ll be supported in this effort by numerous partners, politicians, and city officials—in keeping with the citizen participation motto “Shaping Mainz Together.”
