The Atomium is one of the most original and striking buildings in modern architecture. Designed by André Waterkeyn for the 1958 World Fair in Brussels, this structure is made of 9 interconnected steel spheres connected in a crystal-like lattice modeled after the atomic crystal structure of iron (hence the name Atomium).
The Atomium is 102 meters tall (335 feet) and large enough to accommodate a restaurant and observation platforms and to provide roomy escalators and staircases inside its tubes for visitors to traverse from one sphere to the next.
It is amazing to think that the Atomium was originally built merely as a temporary novelty feature for the World Fair, and was supposed to be dismantled afterwards. Fortunately, it was highly popular and quickly attained iconic status and was spared and is still standing proud after more than 50 years. It exudes unique retro-futuristic charm both inside and out that makes it a delight to visit.
