The Atomium ( ə-TOH-mee-əm) is a landmark building in Brussels (Belgium), originally constructed for the 1958 Brussels World’s Fair (Expo 58). It is located on the Heysel Plateau, where the exhibition took place. It is now a museum.Designed by the engineer André Waterkeyn and architects André and Jean Polak, it stands 102 m (335 ft) tall. Its nine 18 m (60 ft) diameter stainless steel clad spheres are connected, so that the whole forms the shape of a unit cell of an α-iron (ferrite) crystal magnified 165 billion times. Tubes of 3 m (10 ft) diameter connect the spheres along the 12 edges of the cube and all eight vertices to the centre. They enclose stairs, escalators and a lift (in the central, vertical tube) to allow access to the five habitable spheres, which contain exhibit halls and other public spaces. The top sphere includes a restaurant which has a panoramic view of Brussels. This site is served by Heysel/Heizel metro station on line 6 of the Brussels metro.
