The Atomium

The Atomium

The Atomium is a giant steel monument in Heysel Park, Brussels, Belgium, consisting of nine spheres that represent the body-centered cubic structure of an iron crystal magnified 150 billion times. Designed by the architect André Waterkeyn and built for the 1958 World's Fair, the 103-m-high edifice was originally meant to stand for only 6 months. It may be the world's largest cube. Each of its spheres have a diameter of 18 m and are connected by escalators. Three of the upper spheres have no vertical support, and do for safety reasons are not open to the public. However, the top sphere offers a panoramic view of Brussels through its windows, and the lower spheres contain various exhibitions.
