Published on 09/16/2026 at 18:31 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Atomium in Brussels takes the abstract idea of an iron crystal and turns it into a walk-in landmark, with gleaming spheres joined by tubes above the Heysel plateau. Built as the centrepiece of Expo 58, the Brussels World’s Fair in 1958, it has long outlived the event and now serves as a combined viewpoint, museum and exhibition space.
An iron crystal magnified into architecture
Atomium represents a unit cell of an iron crystal, enlarged on an extraordinary scale so that each atom becomes a sphere and each bond a connecting tube. The structure rises to about 102 m (335 ft), making the model as tall as a multi-storey tower and visible from across northern Brussels.giant model of an iron crystal The nine spheres stand for nine iron atoms, arranged in a cubic pattern and linked by tubes that visitors can move through.
The building was designed by engineer André Waterkeyn with architects André and Jean Polak, giving it a clear signature in mid-twentieth-century Belgian modernism.André Waterkeyn and the Polak brothers Completed for the 1958 Brussels World’s Fair, known as Expo 58, it was conceived as the fair’s flagship building and emblem, projecting the optimism of the atomic age in built form.designed and built for the Brussels World’s Fair
Spheres, tubes and what visitors find inside
From the outside, Atomium is a composition of nine metallic spheres connected by twenty tubes, resting on three main supports that carry the entire structure.nine spheres connected by tubes The spheres are clad in aluminium, covering steel shells that give them their structural strength.aluminium-coated steel spheres Inside, several of these spheres are arranged as exhibition spaces, circulation hubs and viewpoints linked by stairs and escalators.
The lowest sphere contains a permanent exhibition on the origins of Atomium and the story of Expo 58, situating the building in its post-war context.permanent exhibition on Expo 58 Other spheres host temporary shows on design, architecture and visual culture, while the top sphere offers a panoramic view over Laeken, the exhibition grounds and the wider Brussels skyline. Long escalators run inside some of the tubes, turning the movement between levels into part of the spatial experience without needing to describe how it feels.
