On the weekend of September 13 and 14, 2025, the Mainz Science Market will once again be inviting visitors to discover, try out and marvel - for the first time on the Platz der Mainzer Republik in front of the Rhineland-Palatinate state parliament. Admission is free. You're warmly invited to our booth: together with four other Leibniz Institutes from Rhineland-Palatinate, IEG will showcase its latest research projects. Discover what we study, the questions that drive us, and why historical research is more relevant than ever. Ask our scientists your questions and explore new perspectives in history with us. While we explore IEG's research together, young guests can discover history in their own creative way through painting and crafting. We look forward to welcoming you! Platz der Mainzer Republik, 55116 Mainz Saturday, September 13 from 10 a.m. to 6 p.m. Sunday, September 14 from 12 p.m. to 6 p.m.
