Built around living trees in 1926, this Beaux-Arts lakeside palace was Geneva's first purpose-built international organization HQ — now home to the WTO.

Every tariff on every product crossing every border on Earth traces back to negotiations inside this lakeside building. Centre William Rappard, on Geneva's southern shore in Switzerland, has housed the machinery of global trade since 1947 — first as the secretariat of GATT, then its successor, the World Trade Organization. The neoclassical facade could pass for a Florentine villa on holiday by Lake Geneva, but behind it, delegates from 164 nations argue over decimal points that determine whether your coffee costs three dollars or five.
The building opened on 6 June 1926 — the first structure in Geneva purpose-built for an international organization. Swiss architect George Epitaux won the commission over 67 competitors with an unusual constraint: preserve the existing lakeside trees. He bent his floor plan around them, and a century later, those same trees still frame the entrance.
Inside, the corridors double as a gallery of interwar idealism. Portuguese azulejo tiles by Jorge Colaço date to 1928, Maurice Denis contributed a mural called "The Dignity of Labour" in 1931, and Gustave-Louis Jaulmes painted the Salle des Pas Perdus in 1940 — each one the work of a world trying to talk its way to peace. Give or take, that's still the project underway upstairs.
You won't stumble across it by accident. The building sits on Rue de Lausanne behind security that reflects its current tenant, but the grounds and periodic open days reveal a place where the twentieth century's faith in institutions remains visible in the stonework, the murals, and the oak-paneled rooms where disputes worth billions are settled over bad coffee.
History
Since 1926, Centre William Rappard has done exactly one thing: given nations a room in which to sit across from each other. The occupants changed — the ILO gave way to GATT in 1947, which gave way to the WTO in 1995 — but the function never did. For a full century, diplomats have walked the same corridors to argue over rules that bind sovereign states, while the lakeside trees Epitaux was ordered to preserve still shade the windows.
Geneva's international quarter has grown enormously since the 1920s, sprouting glass towers and modernist campuses. Centre William Rappard remains neoclassical, deliberately rooted, its stone facade a quiet argument that the institutions inside are meant to outlast their occupants.
The turning point
William Rappard was born in New York in 1883 to Swiss parents — though the WTO's own website lists his birth year as 1887, a discrepancy no one has publicly reconciled. He returned to Switzerland at seventeen, earned his degree at Harvard by 1908, and became what historian Susan Pedersen described as a man who "looked like a Swiss farmer" but moved through diplomatic circles in three languages without breaking stride.
In 1920, Rappard faced the task that would define both his career and his city: persuading Woodrow Wilson to choose Geneva as the seat of the League of Nations. Brussels, The Hague, and several Swiss cities lobbied hard, but Rappard argued that Geneva's neutrality and compactness made it the natural home for a body meant to prevent another war. Wilson agreed — and that single decision transformed Geneva from a prosperous lakeside city into the capital of international cooperation.
Rappard co-founded the Graduate Institute of International Studies in 1927 and delivered the opening address at the 1947 Mont Pelerin Conference, the gathering that launched modern free-market economic thought. When the ILO vacated the building in 1975, there was only one serious candidate for its new name. A park and a road in Geneva also bear it, but the building is the monument that matters.
Not freely — the building is the World Trade Organization headquarters, so public access is restricted. Guided tours are occasionally offered during events like Geneva's Journées du Patrimoine (Heritage Days), and the WTO sometimes arranges group visits by request. The lakeside grounds and exterior, however, are visible from Quai Wilson and the surrounding public paths.
It serves as the headquarters of the World Trade Organization, the body that replaced GATT in 1995. The building has housed international organizations since its inauguration in 1926, when it opened as the first purpose-built home for an international body in Geneva — originally the International Labour Office. A 2008–2013 renovation costing CHF 130 million expanded it with modern conference facilities designed by Group8 and Jens Wittfoht.
A Swiss-born academic and diplomat who convinced Woodrow Wilson to pick Geneva as the League of Nations seat in 1920. Born in New York in 1883 to Swiss parents, he studied at Harvard, spoke three languages without apparent effort, and co-founded the Graduate Institute of International Studies in 1927. He also opened the 1947 Mont Pelerin Conference — the meeting that launched modern free-market economic thought.
Walk along the right bank of Lake Geneva toward the Pâquis district — it takes about 15 minutes from Gare Cornavin. The building sits at 154 Rue de Lausanne, near the Jardin Botanique. Bus lines 1 and 25 stop nearby, and the lakefront promenade from the Bains des Pâquis makes it a pleasant approach on foot.
The building holds several works commissioned across its first two decades. Portuguese artist Jorge Colaço installed elaborate tile panels in 1928, and Maurice Denis added his mural "The Dignity of Labour" in 1931. Gustave-Louis Jaulmes painted murals in the Salle des Pas Perdus in 1940. One painting, "In GATT We Trust," was permanently removed in October 2019 after staff objections over its imagery.
It was the first building in Geneva designed and constructed specifically for an international organization — a fact that still surprises people who assume the Palais des Nations holds that distinction. Inaugurated on 6 June 1926 for the International Labour Office, the neoclassical structure by Swiss architect George Epitaux predates the Palais by over a decade. Its design brief required preserving the lakeside trees, so the building was shaped around them rather than the other way round.
A major renovation and extension ran from 2008 to 2013 at a cost of CHF 130 million — roughly the price of a mid-range Premier League footballer. The Swiss Confederation covered CHF 70 million outright; the remaining 60 million came as a 50-year interest-free loan from FIPOI, the Swiss-Genevan foundation that manages the property. Geneva voters approved the WTO expansion in a 2009 cantonal referendum with 61.8% in favor.
