Inscription on the Reformation Wall, Parc des Bastions, Geneva (1909)

The story that haunts this land

Your journey begins at Place des Nations, facing the Broken Chair. This monumental 5.5-meter-high sculpture, installed in 1997 by Swiss artist Daniel Berset, not only symbolizes victims of anti-personnel mines. Its intentionally broken leg represents mutilations, an echo of conflicts that have marked Geneva's history and ongoing efforts for peace. It was a gift from the International Campaign to Ban Landmines, and its presence in front of the Palais des Nations sets the tone for your quest: to understand how Geneva, the city of the Reformation, became a global center for diplomacy.

A short walk away, the Palais des Nations stands, imposing. Built between 1929 and 1937 as the seat of the League of Nations, it has housed the UN since 1946. This building, the largest UN structure at 35,000 m², has seen key figures in world diplomacy pass through its doors. As you walk its perimeter, you imagine the debates of the General Assembly and the Human Rights Council, institutions which, like the reformers, sought to define new world orders. The Assembly Hall, with its 2,300 seats, contains the world's largest oil painting, created in 1936, an artistic testament to this quest for consensus.

Your route then leads you to the Parc des Bastions, created in 1886 on the former 16th-century fortified bastions. Here stands the Reformation Wall, inaugurated in 1909. This 100-meter-long, 9-meter-high monument depicts major figures of the Reformation, such as Guillaume Farel (1489-1565), John Calvin (1509-1564), Théodore de Bèze (1519-1605), and John Knox (1514-1572). On the ground, a 1909 sundial marks the passage of time, while the 5-meter-high central flame, lit during commemorative events, symbolizes the persistence of their ideas. The park also hosts Europe's largest outdoor giant chess games, installed in the 1950s, linking the intellectualism of the reformers to popular entertainment.

Continuing your exploration of Geneva, you cross the Pont du Mont-Blanc, the first bridge over the Rhône, built in 1609 by Giovanni Giacomo Billozza and rebuilt in 1901 after floods. Named after the alpine peak visible on clear days, it was the first to be electrically lit in 1890. It connects the left bank to the right bank near the Horloge Fleurie (Flower Clock), a masterpiece of floral clockmaking created in 1955. These two sites, though distinct from the themes of the Reformation and human rights, embody Swiss ingenuity and precision, qualities that Geneva's pioneers often put at the service of their ideals.

Your path concludes at St. Pierre Cathedral, whose main construction was completed around 1284 on a Christian site active since the 4th century. It was here that John Calvin preached daily from 1536 to 1564, making this place an epicenter of the Reformation. Climbing the 73-meter-high south tower, classified as a Swiss historical monument, you embrace a panoramic view of Geneva, from Place du Bourg-de-Four, the city's oldest square, to the lake. Archaeological remains reveal a 5th-century crypt and 6th-century Merovingian mosaics, anchoring Geneva's history in a millennial continuity. This journey will have allowed you to link the past of the Reformation to Geneva's contemporary commitments, a city of "Post Tenebras Lux".
