§ From Fairground to Purpose-Built Ground
The Palais des Expositions at the Porte de Versailles began as a conscious attempt to give Paris a permanent, purpose-built trade fair site — something distinct from the grand Universelles with their one-off monuments and their temporary iron halls. The first structures on the site, in the 15th arrondissement on the city's southwestern edge, opened in 1923 alongside the nascent Foire de Paris, which had been searching for a stable home since its founding in 1904. That fair had moved between improvised locations — the Tuileries gardens, the Champ de Mars — before the decision was taken to build for it rather than around it.
The interwar decades saw a first round of construction that established the characteristic ambition of the site: covered halls of considerable floor area, built to a utilitarian standard rather than an architectural one. These were not the vaulted iron-and-glass cathedrals of the 1889 or 1900 Expositions Universelles; they were working sheds scaled to exhibitors. By the late 1920s the site covered roughly 40 hectares of the former fortification zone along the Boulevard Périphérique, land cleared when the Thiers fortifications were demolished after the First World War. The choice of location was pragmatic — the city needed to do something with a decommissioned military perimeter, and the trade fair needed ground.
§ Hall by Hall: The Phases of Expansion
The postwar period forced the real decisions. The Salon de l'Automobile, which had debuted at the Tuileries in 1898, arrived at the Porte de Versailles site as its volumes grew beyond any rival indoor address in Paris. Each new generation of cars, and each increase in attendance, translated into a demand for more covered square metres. The Salon International de l'Agriculture, in its modern form from 1964, brought a different pressure: livestock, machinery, soil samples and refrigerated food halls cannot share their requirements easily with a motor show, which itself cannot easily share with a boat fair. The Salon Nautique, arriving from the 1960s onward, added further incompatible demands for water tanks and heavy rigging. Three major fairs with genuinely different technical requirements, all anchored to the same site, produced expansion by necessity rather than by plan.

The ground grew in numbered pavilions. The current configuration comprises eight halls — designated Halls 1 through 8 — with a total covered exhibition area of approximately 230,000 square metres, making it the largest indoor exhibition space in France by covered floor area. Hall 1, the oldest portion of the fabric, dates in structure to the interwar phase; Halls 4 and 5 were added in postwar expansions driven directly by the Salon de l'Automobile's attendance growth. The most recent major addition was Hall 8, designed by the architect Patrick Berger and completed in 2017: a sweeping canopy of folded steel and glass that registers, for the first time on the site, an architectural ambition comparable to those of the great fair buildings elsewhere in Paris. Its construction displaced a section of the raised Périphérique ring road, a negotiation between the city and the site operator that took years.
§ The Site as Infrastructure
What the Porte de Versailles became — gradually, without a founding master plan — was an infrastructure rather than a monument. The Bureau International des Expositions classifies world expositions as distinct events with fixed international rules; the Porte de Versailles hosts something different: annual, specialist, commercially organised shows that run on their own calendars. The Foire de Paris, the Mondial de l'Auto, the Salon de l'Agriculture, the Salon Nautique and dozens of professional trade fairs rotate through the halls on a cycle that keeps the ground occupied for most of the year. No single exposition built these halls; each hall was built because a particular fair grew past what the previous hall could hold. That is a different logic from the Exposition Universelle — accumulative and market-driven rather than sovereign and celebratory — and it produced a different kind of place: anonymous from outside, indispensable within, a machine for showing things that nobody ever thought to photograph.
