The Atomium is a symbolic modernist structure, located on the Heysel Plateau, which was originally built for the 1958 World's Fair (Expo '58). It consists of nine steel spheres connected by tubes, and forms a model of an iron crystal (specifically, a unit cell), magnified 165 billion times. The architect A. Waterkeyn devoted the building to science. It is now considered a landmark of Brussels. Next to the Atomium, is Mini-Europe miniature park, with 1:25 scale maquettes of famous buildings from across Europe.
