UNESCO World Heritage Day 2026: Working together for peace and understanding

**Sunday, June 7, 2026** The theme of UNESCO World Heritage Day 2026 is "Together for Peace and Understanding," reflecting UNESCO's fundamental principle of working together to preserve humanity's cultural heritage in order to promote understanding and peace between different cultures. The pile dweller "Uhldi," one of the oldest employees of the Unteruhldingen Pile Dwelling Museum, explains how important cooperation was even in the Stone Age and the subsequent Bronze Age. For example, it would have been virtually impossible to transport copper, tin, and even amber thousands of kilometers to the World Heritage Site of the Central European pile dwellings if there had not been people who preferred peaceful exchange to robbery. On this day, Uhldi can be found in the museum's new DISCOVERY TRAIL, where he shares his immense knowledge of prehistory with the audience through practical demonstrations and lively storytelling. Participation in the event is included in the museum admission price.
