The founder of the Red Cross and Nobel Peace Prize laureate Henry Dunant spent the last few years of his life in Heiden. A museum devoted to him has been established in the former district hospital.

Dunant's eventful life, his political, social and religious convictions and the consequences and fruits of his tireless work are illustrated by numerous documents displayed in four themed rooms.

The museum also houses special exhibitions devoted to the themes of peacekeeping, international politics, medicine and health as well as social justice.
