From April 17 to October 19, 1958, Brussels, Belgium hosted one of the largest World’s Fairs of the 20th century. Known as Expo 58, the event drew over 41 million visitors from across the globe. Its official theme was “A World on the Move,” a nod to the rapid technological progress reshaping everyday life in the post-World War II era. The fair ran at the height of the Cold War, and that tension shaped nearly every corner of it.
Advertisements for the fair were everywhere. Posters and promotional materials blanketed Europe and beyond, promising a glimpse of the future. The marketing campaign reflected the fair’s ambition — this was not just a trade show. It was a statement about where the world was headed and which nations were leading the way.
No structure defined Expo 58 more than the Atomium. Built as the fair’s central symbol, it was a model of an iron crystal magnified 165 billion times its actual size. Its nine steel spheres, connected by tubes large enough to walk through, rose dramatically above the fairgrounds. It was unlike anything visitors had ever seen.
The fair featured pavilions from 58 countries, each designed to show off national achievements in culture, industry, and technology. Architects of international standing contributed to the designs, including Le Corbusier and Jean Prouvé. The result was a fairground full of bold, experimental structures that pushed the boundaries of modern design.
The United Kingdom brought a slice of home to Brussels. The British pavilion included a functioning pub called the Britannia, where visitors could sit down for a proper drink amid the spectacle of an international fair. It was a deliberate cultural statement — Britain was showcasing its way of life, not just its industry.
The American Pavilion, designed by architect Wallace Harrison, was a towering steel and glass structure built to project the power and prosperity of the United States. Inside, visitors encountered an early computer and a large-scale model of the Polaris missile system. The message was clear: America was technologically dominant and militarily prepared.
The Soviet Union answered with its own pavilion, designed to put communist achievements on full display. A large statue of Lenin greeted visitors, and a replica of the Sputnik satellite — the first man-made object to orbit Earth, launched just months earlier in October 1957 — hung prominently inside. The USSR also demonstrated color television technology, drawing crowds eager to see the cutting-edge medium.
Beyond the superpower showdown, smaller nations also made their mark. France presented a sleek, modern pavilion that highlighted its design and engineering prowess. The Grand Duchy of Luxembourg, Siam, Austria, and even the Holy See each maintained a presence at the fair. The Belgian Congo pavilion reflected Belgium’s colonial holdings of the time, a dimension of the fair tied directly to the political realities of 1958.
The Philips Pavilion stood out for a different reason. Designed by the composer Iannis Xenakis under Le Corbusier’s direction, it hosted an audio-visual experience called “Poème électronique” — a multimedia composition by Edgard Varèse played through hundreds of speakers. It was one of the most avant-garde moments of the entire fair.
Entertainment ran alongside the exhibitions throughout the fair’s six-month run. Concerts, theatrical performances, and film screenings kept visitors engaged beyond the pavilions. The Tivoli amusement park, modeled after the famous Tivoli Gardens in Copenhagen, provided rides and games for families. It became one of the most visited spots on the entire fairground.
