Historical context
The Atomium is a 102-meter-high steel monument built in Brussels for the Expo 58 World Exhibition. The structure, designed by architect André Waterken and engineers René Sasportas and Jean and André Polak, is a model of the unit cell of the iron crystal lattice 165 billion times larger. Nine spheres connected by tubes symbolize the peaceful use of atomic energy, an important theme of the post-war era. After Expo 58, the Atomium, which was originally intended to be temporary, became a permanent symbol of Brussels. In 2004–2006, the monument underwent a complete restoration costing over 26 million euros, replacing the aluminum covering of the spheres with stainless steel and updating the interiors. The coin commemorates this renovation.
