The Atomium is a working in Brussels initially developed for Expo 58, the 1958 Brussels World's Fair. Outlined by the designer André Waterkeyn and draftsmen André and Jean Polak, it stands 102 m (335 ft) tall. Its nine 18 m (60 ft) measurement stainless steel clad circles are associated so the entire structures the state of a unit cell of an iron precious stone amplified 165 billion times. It is currently an exhibition hall.

Containers of 3 m (10 ft) breadth interface the circles along the 12 edges of the solid shape and every one of the eight vertices to the inside. They encase stairs, elevators and a lift (in the focal, vertical tube) to enable access to the five livable circles which contain show corridors and other open spaces. The best circle incorporates an eatery which has an all encompassing perspective of Brussels.
