Built for the 1958 Brussels World's Fair (Expo '58), the 103-meter (335-foot) tall Atomium monument represents a unit cell of an iron crystal (body-centered cubic), magnified 165 billion times, with vertical body diagonal, with tubes along the 12 edges of the cube and from all 8 vertices to the center.
Nine steel spheres 18 meters in diameter connect via tubes with escalators as long as 35 m, among the longest in Europe. Windows in the top sphere provide a panoramic view of Brussels. Other spheres have 1950s exhibitions. Three upper spheres lacking vertical support are not open to the public for safety reasons.
One of the original ideas for Expo '58 was to build an upside-down Eiffel tower. The architect Waterkeyn didn't like that idea and decided to create something more symbolic of the era.
According to some sources, it is illegal to publish (even self made) pictures of the Atomium, as the copyright is actively enforced by SABAM. **
The Atomium features in the music video for "Headhunter," by Belgian EBM group Front 242.
