The Atomium was designed by the engineer André Waterkeyn and built by the architects André and Jean Polak for the 1958 World Exhibition in Brussels, Belgium. Along with the Manneken-Pis and the Grand-Place, it has become a symbol of the Belgian capital. It is a replica of an iron crystal enlarged 165 billion times.
Of the six spheres accessible to the public, the base sphere is reserved for the permanent exhibition devoted to the 1950s, the World Fair and the construction of the Atomium. Another sphere is used for temporary exhibitions, while a third is used for various events, films, concerts, parties and conferences.
In the central sphere, there is a bar and in the upper sphere, in addition to the panorama, there is a restaurant.
