Under the title “ALLEINSAM,” this year’s OPEN OHR Festival—taking place over Pentecost—will explore the social, political, and health-related causes and consequences of loneliness. The Freie Projektgruppe and the City of Mainz’s Office for Youth and Family invite you to come together at the OPEN OHR Festival from May 22 to 25, 2026, and to turn the Mainz Citadel into a place where no one is left alone with their loneliness.
