An iron crystal turned into architecture
Atomium represents the conventional unit cell of an iron crystal, magnified 165 billion times into a walk-through steel structure.conventional unit cell of an iron crystal It was conceived by engineer André Waterkeyn and realised with architects André and Jean Polak for the 1958 Brussels World’s Fair, bringing the language of atomic models into built form.André Waterkeyn and the Polak brothers
The monument stands about 102 m (335 ft) high above the surrounding exhibition grounds, carried on three steel pillars and a lattice of tubes between its spheres.total height 102m Nine spheres, each with a diameter of around 18 m (59 ft), are linked by 20 tubes with a diameter of roughly 3.3 m, forming the outline of the iron crystal’s cubic structure in space.nine spheres and 20 tubes The whole weighs in the order of 2,400 tonnes in its original specification, making Atomium one of the more substantial steel constructions of its era.total mass 2,400 tons
From Expo pavilion to enduring symbol
Atomium was built between 1956 and 1958 as the flagship pavilion for Expo 58, the Brussels World’s Fair that opened in April 1958.built between 1956 and 1958 The site at Heysel had already hosted an international exhibition in 1935, and the new fair turned this northern plateau into a showcase for post-war optimism and technology.Heysel Plateau exhibitions
Where many World’s Fair pavilions are dismantled, Atomium remained on the Heysel plateau and over time became one of the emblems of Brussels alongside the Grand Place and Manneken Pis.symbol of the Belgian capital Its spheres and connecting tubes have housed exhibitions, a restaurant and viewing spaces, turning what began as a temporary Expo structure into a permanent part of the city’s skyline.
Inside the spheres and across the tubes
Visitors encounter Atomium as both sculpture and building: the spheres form rooms on several levels, while the tubes linking them contain stairs and escalators.discover the Atomium The central vertical tube contains an elevator that was among the fastest in Europe at the time of Expo 58, climbing at about 5 m per second to the upper sphere.fastest lift in Europe in 1958
Escalators run through several of the inclined tubes, and the longest of them measures around 35 m, carrying visitors between exhibition levels inside the structure.35 metre escalator Six of the nine spheres are accessible, with the upper sphere offering a panorama over northern Brussels and the surrounding Heysel grounds.
