« Since brotherhood must unite all men, it must also extend to the wounded, whatever their nation. »— Henri Dunant, A Memory of Solferino, 1862
Your quest begins in Place du Bourg-de-Four, the historic heart of Geneva. This location, once a Roman forum and then a medieval market, has witnessed centuries of exchanges and debates. It was here, in the bustling Geneva of the 19th century, that Henri Dunant drew inspiration for his revolutionary ideas. In 1859, after witnessing the horrors of the Battle of Solferino in Italy, Dunant returned to Geneva and began to outline the principles of a neutral organization to aid the wounded in war. The square, with its fountains and ancient buildings, immerses you in the atmosphere where the vision of the future Red Cross founder was born.
The Hôtel de Ville de Genève, built from the 15th century onwards, is a monument of power and decision-making. It was within its walls that the first Geneva Convention was signed in 1864, a crucial milestone for humanity, establishing the protection of wounded military personnel and medical staff on battlefields. This treaty, the result of the tireless efforts of Henri Dunant and his collaborators from the International Committee of the Red Cross, transformed the laws of war. By exploring this historic site, you connect directly with the foundations of international humanitarian law, a legacy that has endured and developed for over 150 years in Geneva.
Rue Jean-Calvin 12, though unassuming, is a key location in Geneva's history. It houses the site of the Academy of Geneva, founded in 1559 by John Calvin. This institution was a major intellectual center of the Reformation and trained generations of thinkers and leaders. The spirit of rigor and civic engagement that marked this institution undoubtedly influenced the environment in which Henri Dunant evolved. The perseverance and strength of the ideas that germinated here are a distant echo of Dunant's determination to gain acceptance for his proposals to alleviate human suffering, a century later, in the same city of Geneva.
The Mur des Réformateurs (Reformation Wall), erected in 1909, is a monumental tribute to the emblematic figures of the Protestant Reformation, including John Calvin, Guillaume Farel, Théodore de Bèze, and John Knox. This wall recalls Geneva's tradition as a refuge and a promoter of new ideas. Although Dunant worked in a secular context, this edifice illustrates Geneva's capacity to be fertile ground for intellectual movements and world-changing initiatives. The date of its inauguration, a few years after Henri Dunant's Nobel Prize, underscores the continuity of the philanthropic and visionary spirit that animates the city, affirming its role as a capital of human rights and peace.
Your journey concludes at the Monument Brunswick, erected in 1879 in honor of Duke Charles II of Brunswick, who bequeathed his fortune to the city of Geneva. This neo-Gothic mausoleum, inspired by the Scaliger tombs of Verona, symbolizes generosity and philanthropy, values dear to Henri Dunant. The wealth from this donation allowed Geneva to develop its infrastructure and institutions, strengthening its status as an international city. By contemplating this monument, you measure the lasting impact of individual actions on collective destiny, a powerful message that resonates with the life and work of Henri Dunant, the man who, by his sole will, founded one of the world's largest humanitarian organizations, and whose legacy continues to inspire modern Geneva.
