Here is an unusual and huge structure made of steel which is a 3-D representation of an iron crystal magnified 165 billion times.
Known as Atomium, it was designed by André Waterkeyn for the 1958 Brussels World's Fair. The structure officially billed as a monument and is 102 metres (335 ft) tall. Its nine spheres, each of 18 metres diameter, are interconnected by tubes which have escalators within them. The uppermost sphere provides a panoramic view of Brussels.
