Iron Crystal Magnified – The Atomium

Construction of the Atomium, the Belgian pavilion for the World Expo 58 in Brussels, Belgium, 1957. Photo by Dolf Kruger.

Designed by the engineer André Waterkeyn and architects André and Jean Polak, it stands 102 m (335 ft) tall. Its nine 18 m (59 ft) diameter stainless steel clad spheres are connected so that the whole forms the shape of a unit cell of an iron crystal magnified 165 billion times.  – geheugenvannederland.nl
