This alien-looking and vast silvery sculpture near the Bruparck was created in 1958 for the Expo 58 and represents a iron molecule magnified 165 billion times. A mesh of nine corridors leading to nine giant spheres, it was destined to be demolished after the exhibition but proved such a hit with the Bruxellois that it was reprieved and has become a national icon.
Reaching up to 335 feet (102 m) the Atomium underwent a much-needed and rigorous facelift in the early 2000s; the spheres were originally made of an aluminum skin but this has been replaced by stainless steel. An elevator shoots up the central column to the five spheres that are currently open to the public; three provide a permanent record of Expo 58 and two host temporary interactive art and science displays.
The highest sphere stands at 300 feet (92 m) above the ground and now has a glass roof, allowing 360° views across the Heysel Plain towards Brussels; on a clear day Antwerp’s cathedral spire can be spotted on the horizon. This level is also home to Atomium Restaurant, which serves brasserie-style dishes with the finest views in Belgium. At night all nine orbs are illuminated with nearly 3,000 twinkling lights.
